Description

[Technical Field] The present invention relates to a meltability used in a printed wiring board or the like which is required for high-density packaging used in electronic parts and the like. A glass composition for glass fibers excellent in spinnability, a glass fiber formed of the glass composition, and a glass fiber sheet composed of the glass fiber. [Prior Art] With the development of various information and information equipment such as mobile phones or personal digital assistants (PDAs), resistors, capacitors, and integrated circuits A large number of electronic components, in the trend of high-density packaging technology, are packaged on printed wiring boards (also known as printed circuit boards, rigid substrates, and printing) at a high density that was not previously available. There are many cases on the substrate or the printed wiring board. The printed wiring board is a sheet-like composite material in which an appropriate amount of a resin, a glass fiber, a modifying agent, or the like is mixed, and a through hole for mounting various electronic components is provided. An alias such as a module (m〇dule), a board, a unit, or a package is used depending on its function or use. For the glass fiber used for the printed wiring board, a glass composition called e glass which is composed of a nonalkali glass has been previously used. The E glass is excellent in electrical insulating properties, and is excellent in spinnability when the glass fiber is produced in a molten state, and is excellent in workability such as cutting processing. The broken ^ dimension is made of glass. Further, for example, in terms of weight percentage in terms of oxide, the bismuth glass is 52% to 56% & 〇2, 12% 〜16% ΑΙΛ, 5% 〜1%% ho; 16% 〜25 % Ca〇, 〇%~^ of MgO, 0%~2% of alkali metal oxide (r2〇), 〇.〇5%~〇4% Fe203, 0%~1.0% F2 glass material. On the other hand, in recent years, in order to realize the use of printed wiring boards, it is necessary to use high-frequency waves in order to realize high-speed electronic circuits. However, the electrical characteristics of printed wiring boards are emphasized at this time. The transfer speed is inversely proportional to the square root of the dielectric constant (permittiv) • Therefore, it is necessary to have a low dielectric constant in order to increase the transfer speed. Moreover, the dielectric loss is required to be small, so the dielectric dissipation factor must be small. That is, the dielectric constant (ε) of the present invention indicates the number of dimensi〇nless numbers. 'The number of unnecessary causes is the ratio of the dielectric constant of the medium to the dielectric constant of the vacuum. The electrical constant is conventionally expressed as the dielectric constant number (ε). In general, if an alternating current flows into the glass, the glass absorbs energy from the parent current and absorbs it as heat. The absorbed dielectric loss energy is proportional to the dielectric constant and dielectric loss factor determined by the composition and structure of the glass, and is expressed as kfv2x ε tan 5 . Here, 'W denotes dielectric loss energy, k denotes a constant, f denotes a frequency, v2 denotes an electric potential gradient' ε denotes a dielectric constant 'tan5' denotes a dielectric loss factor. From this equation, it is understood that the dielectric constant and the dielectric loss factor are larger, and the higher the frequency, the larger the dielectric loss becomes. Because 201034990 ” w,pi£doc = 'in order to reduce the dielectric loss, it is required to reduce the dielectric constant and dielectric loss. Therefore, the hysteresis and dielectric loss factor are low for the glass fiber used for printed wiring boards. For the glass fiber, the dielectric constant and dielectric for realizing a dielectric constant of 6.7 at a room temperature of 1 MHz and a dielectric loss factor of _Bei 4 = == are disclosed in the η ΓΓΓ ΓΓΓ 831 publication. The loss factor is called the material of the d. For example, the weight percent of the glass in terms of oxide is w〇2, Wa12〇31:=〇m, and the material of the glass has a dielectric constant of about 10 in 丨MHz. ~20x10-4. . ; | 电 电 贝 However, although the electrical properties of D glass are excellent, there are various kinds of printed wiring boards or glass __ process == = = worse than the glare of glass , in the spinning ^ Yi Xi hair break (endbreakage), etc., broken glass

However, as far as the invention disclosed so far is concerned, in order to realize the generation of glass defects having sufficient mechanical properties and easy control of devitrification and the like, a glass material having a low dielectric constant and a low dielectric loss factor is further obtained. For glass fibers with a low dielectric constant and a low dielectric loss factor, there are still problems to be further solved. For example, the glass composition 201034990 of the Japanese Patent Laid-Open Publication No. Hei No. Hei. No. 167759 "uwpif.doc" has problems in reducing the glass fiber_dielectric constant and the dielectric loss factor, but there is a problem in the melting property at the initial stage of glass melting. In the molten glass, air bubbles are likely to remain, and the molten glass is not sufficient. In addition, the printed wiring board is mounted on a large number of electronic devices, and the environment of the electronic device mounted in the surrounding area is various. For example, it is installed in the car. Number 1: A large number of integrated circuits, which are packaged on the printed board in a high-density manner. However, the parts required by the car (4) can be used for reliability from the hot sun in the summer to the road in the north. Moreover, in order to fully secure the passenger space in passenger cars in recent years, the electronic circuit = is placed around the engine room (engine!_) and the engine (four) side, etc., the temperature is higher and the temperature changes more severely than before. There are many cases in the environment. In addition, there is a demand for miniaturization of the size of the mounted substrate. Due to various changes in such conditions, printed wiring boards for automotive use are more demanding than before. Heat resistance and high through-hole reliability. The reason is that it is absolutely necessary to avoid the occurrence of large faults: due to the difference in the coefficient of linear expansion between the printed wiring board and the packaged parts, heat is generated in the solder (can (four) joint) in a high temperature environment. Stress causes solder cracking, which makes it impossible to obtain an electrical connection. H does not allow electronic components used for automotive applications to malfunction in electronic circuits due to large temperature changes, and requires reliable electronic components. Therefore, in order to satisfy such a requirement, it is required to reduce the linear thermal expansion coefficient of the printed wiring board and the packaged component used in the environment for vehicle use, and therefore it is required to reduce the coefficient of linear thermal expansion.

Tieshi recognizes that the f-spinning temperature is high and the viscosity of the glass is not *when the temperature is changed, and the "long" glass is difficult to manufacture in a limited manufacturing environment. High-quality glass with a small fiber diameter, and the glass that is required to make the viscosity of the glass change rapidly due to temperature changes. Japanese Laid-Open Patent Publication No. Hei 8_333137=The glass composition has a tendency to have a high temperature of 1〇3.〇dPa·s, and a “long” glass with a small degree of dependence on the viscosity of the crucible is not suitable for the production of fibers^ Control small glass fiber. Further, there is a problem in that when the spinning temperature is reached, a large load is imposed on the manufacturing equipment, and the life of the manufacturing equipment such as bushing used when the glass fiber is taken out is shortened. The glass composition in Japanese Laid-Open Patent Publication No. 2003-137590 has the following problem: the spinning temperature is as high as 1300 〇c or more, which shortens the service life of the spinning device. Further, in the case of producing a glass fiber having a small fiber diameter, bubbles contained in the molten glass as a defect tend to cause the glass fiber to be cut when the glass fiber is spun. Further, when the glass fiber containing bubbles in the printed wiring board is mixed as a hollow fiber, through-hole plating intrudes into the hollow fiber, thereby causing a risk of poor conduction. The reliability of the board is lowered, which is a problem. When it is a melting temperature standard such as D glass, i〇2 '〇dpa · 201034990^ 3JUDvpif.doc, it is necessary to apply a large amount of energy when melting, and a large amount of hollow fibers are generated. 'In order to reduce the number of bubbles in the molten glass, it is more effective than using the aspirinous acid and the antimony trioxide. The clarifying agent is also Environmental load, the quality of these components contained in the components used in the sub-machine is considered a problem. [Explanation] The object of the present invention is to provide a molten glass or a glass fiber which has a low melting temperature and can be easily obtained, and has excellent spinnability and high chemical stability. A composition for a glass fiber having a low dielectric constant and a low dielectric loss required for a high-density package printed wiring board, and further having a low coefficient of linear thermal expansion, by using the composition for the glass fiber A glass fiber obtained by spinning glass, and a glass fiber sheet composed of the glass fiber. The inventors of the present invention have repeatedly conducted a large number of studies relating to the number of difficult problems required to reliably overcome the use of a printed wiring board capable of high-density packaging, and to stably produce a glass fiber composition of glass fibers having a small fiber diameter. In particular, the action of the alkaline earth metal element in the glass composition is determined by the fact that the above-mentioned various problems are solved by adding these components in a predetermined amount, and it is possible to recognize a glass fiber composition which exhibits excellent properties which have not been hitherto. Since the glass fiber composition is formed into a glass fiber having a small fiber diameter, the glass fiber composition of the present invention is disclosed herein. The glass composition for glass fibers of the present invention is characterized by having a weight percentage of oxidized 201034990 ^ Juoypif.doc, containing 45% to 65% of Si 2 , 1% to 20% of Al 2 〇 3, 13 °/〇~25% of B2〇3, 5.5%~9% of MgO, 0%~10% of CaO, 0%~ι〇/〇 of Li2〇+ Na2〇+ K2〇, Sr〇, and BaO. Here, the weight percentage in terms of oxide means that 45% to 65% of SiO 2 , 1 〇〇 / 0 〜 2 〇〇 / 0 of Al 2 〇 3, 13% 〜 25% of B 2 〇 3, 5.5% ~9% of MgO, 〇%~ι〇〇/〇 of CaO, 0%~1% of 〇Li2〇+ Na2〇+ K20, Sr0, and BaO are as follows. That is, if the elemental components constituting the glass are expressed in terms of oxide by various analytical methods such as chemical analysis and machine analysis, the glass composition is expressed as a range of 45 to 65 weight percent of the Si 2 component. 'Al2〇3 composition is in the range of 1% by weight to 2% by weight. B2〇3 is in the range of 13% by weight to 255% by weight. The Mg〇 component is in the range of 5 5 to 9 weight percent. The Ca0 component is 10% by weight or less, and the total amount of the Li2〇 component, the Na20 component, and the K:2〇 component is 1% by weight or less, and further contains a SrO component and a Ba〇 component. In addition, in the glass composition for glass fiber of the present invention, in addition to the above components, in terms of weight percentage in terms of oxide, Ce02 is 0.01% to 5.0%', and the number of bubbles in the molten glass can be reduced to make the hollow fiber The generation is less, so that a glass fiber having higher homogeneity can be obtained. Further, 'in the glass composition for glass fiber of the present invention, in addition to the above components, 'in terms of weight percent in terms of oxide, SrO is 0.1% 11 201034990 33069pii: doc 〜10%, BaO is 0.1% 〜10%, In the case of a glass composition in which the glass is melted and the so-called devitrification property is low, the glass composition is easily melted, and the glass water and acid resistance are not lowered, which is preferable. In other words, in the same manner as described above, the weight percentage in terms of oxide indicates that 'SrO is 0.1% to 10%, and BaO is 0.1% to 10%, which means that if the elemental component constituting the glass is expressed by the oxide substitution, In addition to the composition of the above glass composition, the 'SrO component is from 0.1% by weight to 1% by weight, and the BaO component is from 0.1% by weight to 1% by weight. The reason for limiting the content rate of each component constituting the glass composition for glass fibers of the present invention is specifically described. The Si 〇 2 component is a f component of the skeleton of the network structure in the glass structure, and is a main component of the glass composition of the present invention. When the content of the SiO 2 component of the glass composition increases, the structural strength of the glass changes. The bigger it is. If the strength of the glass structure is changed to A, the ride becomes a chemically durable glass: a glass composition having a high performance especially in acid resistance. In order to maintain the strength of the glass structure to a sufficient level, the product f, (10) 2% (four) content must be at least large = 45 weight percent, more preferably greater than or equal to the mail weight percentage. If the content of the ton component in the glass composition is increased, the sleek rate and the value become large. The result is that the technique is efficient by the secret method and the temperature is: =: high: the device. It is also produced in the management of equipment at the time of manufacture; about 201043090 uovpif.doc It is easy to obtain a homogeneous molten glass which does not remain in the vitrification reaction when the glass is melted, and does not need to be melted in the glass. The excess heat energy and the high spinnability in the production of the glass fiber are required to be 1 or less of the content of the component. Ο Ο Α1ζ〇3 is an effective component for realizing the chemical stability and mechanical stability of glass. It also has the effect of crystallizing and phase separation of crystals in molten glass by only containing an appropriate amount in the glass. The situation, but right big:!: 3 will increase the viscosity of the molten glass. When the content of the =2〇3 component in the glass composition is less than 10% by weight, the phase separation property at the time of melting deteriorates, which is not preferable. The deterioration of the phase separation property in the molten glass leads to deterioration of the acid resistance of the obtained glass fiber, which is not preferable. Here, the phase separation is a phenomenon in which the f-glass is separated into a plurality of glass phases equal to two. On the other two sides, if the content of the Α12〇3 component in the glass composition is excessively increased, the other components are particularly affected by the content of {Si〇2 age = therefore, the content of the 3 component is == ^ at 2G weight percent'. The weight is less than or equal to 18% by weight = 17% by weight, and the step is preferably less than equal to 100% by weight, and most preferably 15% by weight or less.

The heart is easy to "evil" If the 组2〇3 component of the glass group exceeds 25 weights by π, and the acidity and phase separation of the j's deteriorate, it is not good. Broken glass

The component of the MgO is a component which has a function of facilitating the aid of the glass raw material, and is effective for the low temperature of the temperature of 102 〇dPa · s, and is effective for the ship. , which helps to make a homogeneous glass. Further, it has a function of lowering the temperature of 1 〇 3 〇 dPa.s and shortening the glass, so that the productivity is very good, and it is possible to efficiently produce glass fibers having a small fiber diameter. However, in the glass composition, in order to make the Mg 〇 function effectively, the spinning temperature, that is, the high-temperature viscosity in the vicinity of 103·0 dPa·s, is lowered, and it is necessary to set the MgO component to 5.5 or more. percentage. On the other hand, when the content of the MgO component in the glass composition is too large, the phase separation property of the molten glass becomes high, and the acid resistance is deteriorated. Further, the dielectric constant also rises, so from this point of view, it is not preferable that the MgO component exceeds 9 weight%.

In the same manner as the MgO component, the CaO component has a function of lowering the viscosity of the molten glass corresponding to the temperature of 102 GdPa·s, and the component having the soil-measuring metal element has the smallest increase in the dielectric constant. However, 14 201034990 j^uoypif.doc If the Ca0 component is contained in a large amount in the glass composition, the phase separation property becomes high and the acidity of the glass is lowered. The dielectric constant of p glass also increases as the component (5) increases. Therefore, it is not good if the Ca0 component exceeds 1% by weight.碱 The alkali metal component of the tonification of the glass composition in the glass composition represented by the sputum component, the sputum component, or the K2 component is heated in a state in which a plurality of glass raw materials are used to melt the glass. In addition, it functions as a so-called co-solvent which facilitates the formation of a glass melt, and also has a function of lowering the high-temperature viscosity, and the coffee component or the K2 component is set to 3 in the glass composition. When the value is increased, the value of the glassy dielectric factor increases, so the upper limit of the total amount is up to 1 weight percent. The component of =0 is a component which lowers the viscosity of the martensite which is equivalent to the temperature of 1 (p dPa · s, and further reduces the spinning temperature in the vicinity of 1G3.〇dpa · S of the molten glass. However, its effect is not as good as that of Mg〇 or Ca0. However, the Sr〇 component has the effect of suppressing the deterioration of the phase separation when _(4) is caused by the increase of Mg〇 or (5)/knife, and the accompanying acid resistance of the glass. The component of the reduced action is therefore necessary in the present invention. The various effects of containing such a Sr0 component become more pronounced in the case where the glass contains ytterbium in a weight percentage equal to Q1. When the composition is a glass composition of Bolivia (IV), if it is too large, it will become a long glass, and it becomes difficult to make a glass age|small glass age. From this point of view, the upper limit of the SfO component containing the upper limit is 10% by weight. If the glass is molten, if the phase separation is 15 201034990

When J3U〇ypilld〇C deteriorates, the molten glass is separated into an acid-rich phase and a poor acid-resistant phase. At this time, the acid-resistant phase determines the acid resistance of the glass fiber, so the acid resistance of the glass fiber is deteriorated, so it is poor. .

In the same manner as the SrO component, the BaO component lowers the viscosity of the molten glass corresponding to the temperature of i〇2.g dPa·s, and further reduces the spinning temperature in the vicinity of 103·0 dPa·s of the molten glass. Ingredients, but its effect is not as good as MgO or CaO. However, the BaO component is a component which has an effect of suppressing the deterioration of the phase separation property due to an increase in the Mg〇 or CaO component and the subsequent deterioration of the acid resistance of the glass, and is used for the purpose of the invention in the same manner as the SrO component. Essential ingredients. The BaO component is also the same as the sr〇 component. The effect of the inclusion is more pronounced in the case where the glass composition contains 0.1% by weight or more. On the other hand, when the Ba 〇 component is a glass composition for glass fibers, if the content is too large, the liquidus temperature is deteriorated and the glass becomes long, and it becomes difficult to produce a glass fiber having a small fiber diameter. From this point of view, it is preferred to contain the B aO component in a range of up to 10% by weight. The term "long glass" refers to a glass having a small viscosity dependence on temperature change, and it is difficult to cure to _ by cooling. In addition, the SrO component and the Ba0 component are likely to form crystals, and if the component (10) is contained in the glass composition containing Si〇2, the sr〇·si〇2 crystal is easily precipitated, and if the Ba〇 component is contained, it is easy. Precipitation (4) • 2 & 02 crystals' As a result, the liquidus temperature of the glass tends to increase. When the temperature of the spinning glasson_liquid phase is high, the bushing nozzle (secret η〇ΖΖ10' is clogged with the lining nozzle due to the precipitated crystal, and the glass fiber is cut during spinning, which is a problem. If the composition of the glass is 16 201034990 ojuoypif.doc exists with the SrO component and the Ba0 component' then the glass composition enters into the eutectic region of Sr (>Si〇2 and Ba0.2Si〇2, thereby causing the liquidus temperature of the glass Since it is difficult to precipitate crystals in spinning, it is preferable to contain both the SrO component and the BaO component in the glass composition, that is, the SrO component and the Ba〇 component.

The Ce〇2 component acts to clarify the bubbles which are present as defects in the molten glass, and the Ce〇2 component can be appropriately added as a clarifying agent for the non-environmentally loaded substance, but CeC2 The clarification effect of the component is more apparent in the case where the weight percentage in terms of oxide is expressed as 001% or more, and more preferably 0.02% or more. However, if the Ce〇2 component is added in a large amount, there is a case where the devitrification property of the molten glass is affected. In this regard, the weight percentage in terms of oxide should not exceed 5%. In order to achieve a more stable quality, the upper limit is preferably at most 4%, and the better 疋 is at most 2%. If it is the best amount of addition, it is possible to achieve the non-hollowing of the 〇 fiber. In addition to the above-mentioned components, the glass composition for glass fibers of the present invention may contain various components in a range which does not greatly affect the performance of the glass composition for glass fibers of the present invention as needed. If a component which can be used as a component of the == surface fiber-glass composite is described as a specific example, it can be expressed as a weight percentage of 3% or less and contains Zr〇2, P2〇5, and Fe2〇. 3, s〇2, Cb, F2, 仏〇3, Nb2〇5 and γ2〇3 and other rare earth oxides (pool (10) also) or Μο〇3. 17 201034990 ^juoypif.doc Moreover, in addition to the above ingredients, it may contain a trace component of up to 0.1% by weight. For example, various trace components such as Cr2〇3, H2〇, 〇H, %, cS, CO, He, Ne, Ar, and N2 are suitable for 2. Further, in the glass composition for glass fibers of the present invention, the glass may contain a trace amount of a precious metal element if it does not greatly affect the performance of the glass composition for glass fibers. For example, it may also contain the largest metal elements such as Pt, Rh, and Os, which are expressed in terms of weight percentage, and contain pt, Rh, and 铀s and other uranium gold nTj Α8+ « In the glass composition for rayon fiber, in addition to the components, expressed as weight percent in terms of oxide, Ca 〇, SrO, and BaQ doping metal oxides are measured in terms of the age of Na ~ 25 〇 / 〇, SK) and BaO In the range of 〇.151 °·50, which is converted to the earth metal oxide, it is possible to suppress the phase of the glass during the melting, and to avoid the decrease in the acid resistance caused by the phase separation, and the spinning temperature is lowered. The short glass 'is therefore better to improve the productivity of the glass (-Mow fine), so it is preferable. Moreover, when = =, the molten glass is formed due to precipitation and phase separation of crystals: two: the risk of the state is small, the temperature dependence of the heterogeneous temperature near the spinning temperature is large, and the glass fiber composed of short and sticky is composed of glass. The material, and the prescribed dielectric constant and dielectric loss factor, are preferred. Further, the weight percentage in terms of oxide is expressed as SrO Ba〇 ]〇〇/_ 25/. , the total amount of Sr〇 and Ba0 divided by the soil metal oxide conversion J8 201034990 jjuoypif.doc measured value in the range of 0·15 to 〇·50, is the oxidation of the fish The total value expressed by the percentage is a range of α ΐ 5 to (4), which is a total value expressed by the weight percentage of the oxides of Mg, Ca, Sr, and Ba of the soil-based oxide element. If expressed in terms of weight percent of oxides, the total amount of Mg〇, (5), (10) ^, and BaO _ soil metal ship fresh is less than 1 () weight ratio ‘

The viscosity of the glass in the state is high, so the molding temperature is too high; the spinning property of the fiber is lowered. On the other hand, when the total percentage of conversion of 'Mg〇, Ca〇, 齢, and 验 验 超过 超过 超过 超过 超过 超过 超过 超过 超过 超过 超过 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 Further, if the value obtained by dividing the total amount of the (10) # assist by the total amount of the soil-measuring metal oxide is less than 0.15, the content ratio of MgO and Ca0 is increased, thereby tending to increase the phase separation property of the molten glass. When it is enlarged, and the number of hoists is changed, the number of hoists is also changed, so it is not good. On the other hand, when the values of SrO and BaO are more than the total amount in terms of alkaline earth metal oxides, the dielectric constant becomes too high. Further, since the spinning temperature, i.e., the Tv becomes constant, and the glass develops in the long direction, the spinning property is lowered, and it becomes difficult to produce a glass fiber having a small fiber diameter. Regarding the glass composition for glass fibers of the present invention, in addition to the above, if the dielectric constant at a tributary rate of 1 MHz is 6.0 or less and the dielectric loss factor is 2 〇χι〇_4 or less, the printed wiring board The dielectric loss is small, so it is better than 19, 201034990 ^^uoypif.doc and 'the glass composition for glass fiber of the present invention, except for the above, if the dielectric constant is less than or equal to 6.0 at a frequency of 10 GHz, and When the electric loss factor is less than or equal to l〇〇xl 〇 -4, the dielectric loss is further reduced in the use of a high-frequency printed wiring board, which is preferable. In addition to the above, when the volume resistivity i 〇 gp at 150 ° C is greater than or equal to 13 Q.cm, the glass composition for a glass fiber of the present invention has a large electrical resistance, so that it is stable when used as a printed wiring board or the like. Performance. Further, the glass composition for glass fibers of the present invention has a temperature Ty of 103 GdPa.s of less than 130 (TC, a value obtained by subtracting a temperature Tx of 1〇7·6 〇dPa·s from Ty, except for the above. In the range of (3:450 °C), the glass fiber can be efficiently produced without changing the spinning device and the spinning method of the glass fiber. Therefore, it is preferable to use it from 103G dPa. When the temperature Ty of S is subtracted from the temperature Tx of 107.6 dPa · s and the value obtained is 45 CTC or more, the viscosity of the glass becomes long. Therefore, if the glass fiber of the glass fiber having a small fiber diameter is to be spun, it is self-disposed. The molten glass which is extracted from the tip end of the nozzle on the liner has a curved surface shape formed under the nozzle, that is, a meniscus, which is unstable, and thus has a problem that the fiber can not be obtained from the uniform stable spinning property. On the other hand, if the temperature obtained by subtracting the temperature 〇1·7·6 dPa · S from the temperature Ty of 1〇3·0 dPa · s is less than or equal to 300 ° C, the viscosity of the glassy soil becomes too short. Therefore, there arises a problem of other manufacturing conditions for obtaining a predetermined fiber diameter. When the setting range such as the drawing speed and the cooling condition is small, the management of the fiber diameter becomes difficult. The glass dimension of the present invention is formed by the glass composition of the present invention, which is formed by the glass of the glass of the present invention, and the diameter of the glass fiber is 20 201034990 jjuoypif. The average value is from 3 to 72. Therefore, in particular, when it is necessary to use high-density and _ printed wiring, etc., the performance of the composite material for printed wiring board use. When the average value of the diameter of the glass fiber is less than 3 _, the fiber diameter is also reduced, and (10) the ray fiber is produced to produce a low tree. Moreover, it is due to the use of the manufactured glass fiber. Environment and time in Asia

The problem is therefore not good. 〃甘 but "J--the aspect" when the average diameter of the glass fibers exceeds 7 melons 5, even if the glass fibers formed by the glass composition of the present invention are not used, = can be made by (4) self-precision The glass fiber formed by the constant glass composition, and the glass lacking p I : ° 'glass broke, so the fiber lacking the stability of k is less. The Lang fiber of the present invention is made of the glass fiber of the present invention.

In addition, the glass fiber of the present invention has a bubble content of 0.01 or less, particularly 0,001 /m or less, in addition to the above. When it is used in the use of the printed wiring board, the available defects are reduced: all ===: The design of the printed wiring board is as follows: the bubble content is 0.001/m or less, which means that each glass is The number of bubbles in the filament is less than or equal to the tamping, and the count of the number of bubbles is not broken for all the bubbles having a length of the bubble above the enamel. The ratio of the bubbles indicates that the weight is a broken glass. The surface is coated with a glass fiber of a coating material which imparts a desired physical chemistry, and may be coated with a sizing agent, an antistatic agent, a surfactant, an antioxidant, a film forming agent, A glass fiber of a mixture or a lubricant.

If the CV value of the glass fiber exceeds 1% by mass, failure occurs in the formability of a precise shape, and the like, which is not preferable. Therefore, the cv value of the surface fiber diameter is smaller than the number of glass lengths of the _cafe, which is a county of tang, spun yarn or roving, which is a table.

First, a plurality of glass raw materials such as a predetermined amount of natural glass raw materials and chemically synthesized raw materials are weighed in g units of three decimal places, and are each glass composition of Table 1. Next, a glass raw material mixed batch (b^tch) mixed in such a manner that the plurality of raw materials are in a homogeneous state is prepared. The glass raw material mixed batch is thrown into a thief-made lion with a $(8) 〇 ee reading (10). It: owe (four) to the heating furnace, the raw material = the platinum lanthanum of the batch material, in the atmospheric environment 155 (heating for 5 hours under rc', the glass raw material mixed batch chemical reaction at high temperature becomes dissolved 35 glass. In order to make the fused glass into a homogeneous state, the molten glass is stirred by a heat-resistant stirring bar during heating and melting. Thus, the molten glass which is in a homogeneous state flows out to a predetermined fireproof, template In the (template), the slip casting is performed in the slow cooling furnace to perform annealing treatment to room temperature, thereby obtaining a glass molded body used in a test or the like. The glass molded body was measured for various physical properties and the like of each of the glass compositions of the examples of the present invention in the following order. The results of the measurement were summarized in Table 1. The measurement of the linear thermal expansion coefficient is the United States country. NRM (National Institute of Standards and Technology) SRM-731, SRM-738 as the known coefficient of linear thermal expansion The standard sample is used and the average linear thermal expansion system 33 201034990 33069pif.doc is measured by a well-known linear thermal expansion measuring machine that has been calibrated in the temperature range of 30 C to 380 C. The lower the value of the coefficient of thermal expansion of the line In addition, even when the temperature changes greatly, the expansion of the glass fiber becomes smaller, and as a result, the temperature of the case when the printed wiring board using the glass fiber is mounted on the electronic device is caused.

Increased reliability. Μ日关曰JJ For the measurement of the high-temperature viscosity of the glazed glass, 1〇3·0 coffee·s = (Ty), 'the glass sample will be injected to the oxy-pour in a manner that is appropriate in advance. (ahlmina), after the addition of the force t to the molten state, the calculation of the viscosity curve obtained by multiple measurements of the viscous values measured by the material pulling method is calculated. In the value of the Ty-Tx in the table, the value of the temperature corresponding to the temperature of 1〇7·6 coffee·s, that is, the softening point, is subtracted from the value of the temperature of ι〇3〇milk·s. Further, the measurement of the softening point means a value measured by MW (10). The smaller the value of Ty - Tx, the higher the viscosity of the viscosity, the larger the glass is. The shorter the glass, the easier it is to be self-glazed and the state of being solidified. Therefore, after the nozzle attached to the bushing is spun on the melt=glass, the meniscus is stable even under the same cooling conditions. The glass fiber can be produced without cutting. The longer the dependence on the glass, the longer the meniscus becomes and the more unstable, because the equipment used for the production of glass fibers, such as cold heading conditions, is strengthened. In addition, it is said that the fine corpus callosum is cut into a regular shape and pulverized into a predetermined particle size to adjust the surface area in addition to the surface area of the grain. (4) In this state, the volume of the volume is filled with the appropriate bulk density, and the person is allowed to stand in the indirect heating type temperature gradient furnace with the highest temperature deficiencies of 34 201034990 huoypif.doc °c in the atmosphere. The heating operation was carried out for 16 hours. Thereafter, the test body was taken out together with the platinum container. After standing to cool to room temperature, the liquidus temperature T1 was determined by a polarizing microscope. The value of Ty-TL in the table was from 103 GdPa. The value of the temperature of S is obtained by subtracting the value of the liquidus temperature TL. The larger the value of Ty_TL, the more the crystal which hinders the spinning operation is not easily precipitated near the spinning temperature, thereby ensuring stability. Spinning state. For increasing the value of this Ty - TL, the temperature Ty of '103 d0 · S corresponding to the spinning temperature is increased, 'but if so' the energy required to melt the glass. Increasing, resulting in increased manufacturing costs And the problem that the service life of the attached equipment such as the bushing device is shortened. The volume resistivity at 150 °C is a value measured at 150 ° C according to ASTMC657-78. The higher the value of the volume resistance, the even The printed wiring board for the twist package can also exhibit stable electrical insulation performance. For the measurement of the dielectric constant (ε) at a frequency of 1 MHz and the dielectric loss factor (tan (5), use 1200. Sand paper 试样 A sample of two surfaces having a thickness of 3 mm machined into a glass specimen of 50 mm x 50 mm x 3 mm. The measurement is based on ASTM m 50-87, by using horizontal The 4192A impedance analyzer manufactured by Y〇k〇gawa HeWlett-Packard, obtained at room temperature, has a dielectric constant (ε) at a frequency of i〇GHz and dielectric loss. The factor (tan(5) is measured using a short-circuited dielectric resonator method according to JIS R1627:1996, using a network analyzer manufactured by Agilent (35 201034990 33069pif.doc analyzer ) 'Measurement at temperature The smaller the dielectric constant and the dielectric loss factor are, the smaller the dielectric loss of the printed shipboard becomes when the glass fiber is used in the use of the printed wiring board. In order to remove the finely pulverized material and to have a surface area of a predetermined range, the particle size is adjusted to be in the range of 3 Torr to 5 Torr, and in this state, the pulverized material corresponding to 丨cm 3 is expressed as a percentage by weight. 5 cc of 10% aqueous hydrochloric acid was placed in an acid-resistant sealed container, and in this state, it was kept in a constant-temperature shaker set at 8 ° C for 16 hours, and the liquid portion was removed by filtration and dried at 11 ° C. The machine is dried and dried to obtain a constant value of the weight of the glass. Then, the decrease rate of the weight value after the acid treatment with respect to the weight value of the glass initially charged was measured. The measured value of the reduction rate thus obtained is 3% or more, and it has been confirmed that the glass of the corrosion reaction on the surface of the glass due to hydrochloric acid in the acid resistance test is a sample of the reaction product. The acidity of the acid is reduced, and it is judged as X' as for other samples. The reason for this is that when a reaction product is formed by a corrosion reaction, in the plating treatment or the like which is performed in the process of producing a printed wiring board using glass fibers, the acid treatment ◎ prevents the homogeneous processing state from being ensured. The risk of lowering the yield is higher. According to the above test, the following can be clarified. That is, in the samples of Tests Mo. 1 to 12 of the examples of the present invention, the glass composition of the sample is expressed by weight percent in terms of oxide, and SiO 2 is in the range of 47.4% to 54.5%, and Al 2 〇 3 is at In the range of 11.7% to 18.7%, b2〇3 is in the range of 14.0% to 2〇.〇〇/〇,]^0 is in the range of 5.5%~8.7%, €&0 36 201034990. jjuoypif.doc In the range of 3.5% to 8.8%, Li2O + Na2O + K2O is in the range of 0.1% to 0.4%, SrO is in the range of ι.ι〇/0 to 8.8%, and Ba〇 is in the range of 0.8/> In the range of 5.0%, the total amount of soil-measuring metal oxides for Mg〇, CaO, SrO and BaO is in the range of 15.2%~21.4%, and the total amount of SrO and BaO is divided by the alkaline earth metal oxide. The combined value is in the range of 0.20 to 0.45, CeO^〇.i〇/. ~〇.9〇/. In the range. Further, as shown in the items in Table 1, the average linear thermal expansion coefficient (lnean coefflcient of linear thermal) in the temperature range of 30 ° c to 380 ° (: in the example of the present invention is at 3·2 χ 10·7 / ° (: ~ 49. Within the range of 〇xl〇-7/°c, the temperature corresponding to the spinning temperature is 1 〇3·0 dPa · s at a temperature of 1丨94. 〇~1298 °C, the temperature of 1076 dPa · s Tx is in the range of 828. (: 880 to 880. (where: the value of Ty-Τχ indicating the temperature dependence of viscosity is in the range of 々 it to 426 ° C. Further, the liquidus temperature of the example of the present invention Tl is in the range of 1000 ° C or less to l〇95t, so the value of Ty_TL is in the range of 162 C to 251 C. In addition, the temperature Tw of 10 dPa · s which becomes the standard enthalpy of the melting temperature is 1384°. The range of C to 1502 ° C becomes lower than that of D glass. Moreover, regarding the electrical properties, the volume resistivity iogp at 150 ° C of the example of the present invention is in the range of 133 Q.cm to 179 Ω · cm.

The dielectric loss factor (tan) at a frequency of 1 GHz is 0.0038~ In the range of 〇〇〇96, the necessary condition that the dielectric loss factor is less than or equal to l〇〇xl〇_4 is also satisfied. In addition, the number of hollow fibers is not less than or equal to 1.5/100,000 filaments. Sample No. 1 to Sample No. 10 of the inventive example have better properties as the glass fiber composition of the present invention. Hereinafter, a sample having a characteristic feature in the examples of the present invention will be described. The glass composition of the sample No. 1 of the example, si〇2 was 47 4%, which was the lowest content rate, but was compensated by the fact that the content of b2〇3 was 20.0%, and the expansion coefficient was 44.7χ1 ( Τ7/ΐ, is a low enough value to indicate The temperature dependence of Ty-Τχ is 36 generations, which is in the level of no problem, and is equivalent to the spinning temperature (4) Ty $ 1194 〇C, which becomes the melting temperature = standard 妒. The temperature Tw of dpa · s is 138 generations. , is low enough, value. Further, the TL as the liquidus temperature is 1020 or less. (:, Ty- = value = 卩 is the underestimation of the boots, because the value of the money IL is two or two large) In addition, the volume resistivity is 17.5D.cm, which is enough red π go, 'and the frequency is 1MHZ The dielectric constant £ is 5.5 (), the dielectric loss is 2 〇 2 〇 1 〇 'the dielectric constant ε at a frequency of 10 GHz is 5.6, and the ^ & Α ~ (8) 42, both show no disadvantages of the smaller The value of the composition is low, and the composition of the reaction product is not confirmed to contain CeQ, ?i°, and the glass of the sample Ncu of this example is not produced in order to promote the clarification of the molten glass. 201034990 uoypif.doc hollow fiber. Thus, the glass composition of the sample N〇1 of the example corresponds to the present invention. Therefore, the evaluation of the glass fiber by the glass molded body confirmed that the glass fiber can be spun out. There is a problem such as devitrification, and no bubbles remain in the glass fiber, and the number of hollow fibers in the glass fiber is calculated to be 1 or less than 2/1G 10,000 filaments. ◎ ❹ Example The glass composition of sample No. 2 has a characteristic that Al2〇3 is 丨丨7% and has a minimum content rate. The glass composition of the sample Nq.2 of this example contains Ce〇2. This sample N〇.2 is a typical sample of the present invention, and has a coefficient of expansion of 44.4×10 7 /. (:, also has no disadvantages. Low value, and indicates the temperature of the viscosity t Ϊ ί The value of ITX is 391 ° C, which has the short viscosity of the dog. It becomes the standard of the melting temperature, and the temperature of dPa · s is as low as (4) generation. L is the value of the 1G54t, and the Ty-value shows a sufficiently large value of C. The volume domain is sufficiently large to be 170 Ω, and the dielectric constant U at a frequency of 1 为 is 5.49, dielectric loss = number ( Tan5) is 0.0014, the frequency is 1〇gh number....6, the dielectric loss factor is _, the average of any value and the acid resistance is also the same as Wπ ', not m 5丨u 4 , the weight reduction rate Low and also Νο.2, using a nozzle to perform the spinning ^ = 5 ·. The evaluation of the glass fiber can be: the fiber glass manufacturing equipment increases the large change and the stable spinning just spinning The obtained surface fiber forest will produce ^卩:" There will be no bubbles remaining in the glass fiber, = only = empty weaving dimension meets less than or equal to - 10,000 root length; == 39 201034990 3306 9pii.doc fiber. And the average fiber diameter of 200 glass fibers is 5〇# m, the standard deviation is 0.40 // m ' Multiply the value obtained by dividing the standard deviation of the fiber diameter by the average value of the fiber diameter. The cv value obtained in the first step is 8%, and has good quality. It is thus clear that the glass fiber having the use as a printed wiring board has excellent quality and performance. Therefore, the glass fiber is woven flat to produce a pre-form: The obtained printed wiring board can be a printed wiring board that fully exhibits design performance. The glass composition of the sample No. 4 of the example is the inclusion of Ba〇 in the example, the largest glass composition, but the average linear thermal expansion coefficient is 4〇4χ 107/C, which also has a very small value, in addition to 1〇2 The temperature Tw of 〇dPa · s is 1491 ° C, and the temperature of 10 m dPa · s is 1284 t, which indicates the viscosity temperature, and the value of Ty-Tx according to the property is 409 t, which is a very short glass. Moreover, in terms of electrical properties, the dielectric constant (ε) at a frequency of 1 MHz is 5.46, the dielectric loss factor (tan 5) is 0.0012, and the dielectric constant ε at a frequency of 1 GHz is 5.6. The dielectric loss factor is 〇.〇〇38, which satisfies the necessary conditions for this month. In addition, as for the acid resistance, in the same manner as in the case of sample No. 1, etc., the amount of reduction is low and the formation of the reaction product is not confirmed. Therefore, when the evaluation of the glass fiberization is performed, the previous glass may not be used. The manufacturing equipment adds a large change to perform a stable spinning operation. It can be found that the glass fiber composed of the glass of the sample Ν〇·4 thus obtained does not cause problems such as knife phase and devitrification, and no gas/package remains in the glass fiber and the calculation glass is spun out. The number of hollow fibers in the fiber can satisfy a homogenous glass fiber of 2 or 100,000 filaments. Using the glass composition of the sample Ν〇2 obtained as described above, the glass cloth of the plain fabric of 201034990 jJU0ypif.doc can obtain a glass cloth having a small number of hollow fibers and a low dielectric constant and dielectric loss factor, and can be used as printing. Good performance for wiring substrate applications.

The glass composition of the sample No. 101 of the comparative example has a similar composition of a glass wheel having a 盥^ Ε glass, but the linear thermal expansion coefficient is as high as 1 〇/t: and the dielectric constant at a frequency of 1 dirty is as high as 7.00, and The dielectric constant at the second rate of 10 GHz is also high. 8. Therefore, it is different from the king of the present invention. The glass composition of the comparative example N〇.l02 does not contain Sr〇, Ba〇, 42 201034990. o^uuypif.doc but the content of Si〇2 is as high as 76.i〇/. Therefore, acid resistance has not deteriorated. However, since the content of si〇2 is high, the temperature of 1〇3·ο dpa·s which is equivalent to the spinning temperature becomes a value of up to 1,336 °C. When the glass fiber is spun for a long period of time, deterioration of the manufactured equipment is caused, and there is a problem in economy. Further, the temperature Tw which is a standard of the melting temperature of 1 〇 2.g dPa · s is 1600 ° C or more, which is extremely high. Therefore, bubbles are likely to remain in the glass when the glass is melted, and the value of Ty - Tx is 526 ° C, which is a long glass and has a problem in spinnability. 〇 With respect to the glass composition of sample No. 103 of the comparative example, the ratio of the total amount of sr〇 to Ba〇 to the total amount of the alkaline earth metal oxide exceeds 〇5. The temperature of 1〇3.0 dPa·s exceeds 14〇〇. . 〇, the value of Ty-Tx is 536 ° C, which is a long glass. Therefore, it is difficult to produce a glass fiber having a small fiber diameter, and there is a problem in the meltability and spinnability of the molten glass. 1〇2·0 dPa · s temperature

Tw is also high and does not contain Ce〇2, so bubbles are easily left in the glass when the glass melts. Therefore, it is impossible to produce the glass fiber satisfying the required number of hollow fibers of 2 or 100,000 filaments as required by the glass composition. Moreover, the dielectric loss factor of 〇 at a frequency of 1 MHz is as high as 0.0025, and the dielectric loss factor at a frequency of 1 〇 GHz 4 is as high as 0.0108, so there is a problem that the dielectric loss becomes large and the transmission speed becomes slow. The glass composition of the sample No. 104 of the comparative example was a glass composition containing no & 〇 and BaO, and the ratio of the total amount of sr〇 to BaO to the total amount of the soil-measuring metal oxide was as low as 〇.〇〇. . Therefore, the temperature of 103. 〇 dPa· s is as high as 1332 °C. The temperature of 102. 〇dPa.s, which is the standard of the melting temperature, is also as high as 1568 ° C or 1568 ° C or more, and there are many "bubbles" remaining when the glass melts. 43 201034990 33069pif.doc The phase separation property was confirmed at the time of glass melting and melting, and the reaction product which reacted with hydrochloric acid was confirmed in the acidity test. Therefore, there is a concern that etching (etching) processing in the process of the printed wiring board is problematic. . The volume resistivity of 1 〇 gp is 12.7 Ω · cm, which is low in electrical reliability as a printed wiring board. Regarding the glass composition of the sample No. 105 of the comparative example, Sr〇 and Ba0 & The ratio of the tenth to the total amount of the soil metal emulsion is as low as 〇. The glass of the sample No. 105 was a glass composition having a dielectric constant of 6.10 at a frequency of 丨MHz and a dielectric constant of 6 2 at a frequency of 10 GHz. Further, the dielectric loss factor of the sample at a frequency of 1 MHz is as high as 0.0025, and the dielectric loss factor at a frequency of 10 GHz is as high as 0.0127, so that there is a problem that the dielectric loss becomes large and the transmission speed becomes slow. Further, a significant phase separation property was observed when the glass was melted, and as a result of the remarkable phase separation property which adversely affected the acid resistance, it was confirmed that the glass composition was problematic.

Q According to the series of evaluations carried out in the examples and comparative examples shown above, it is clear that the glass composition for glass fibers of the present invention is used to form a printed wiring board for achieving high-density packaging (4) a glass fiber having a small fiber diameter. = It is good, and it is excellent in spinnability in the manufacture of glass fiber, and can provide a glass fiber of a stable quality with high manufacturing efficiency.

Description of the Invention: [Technical Field] The present invention relates to a necessary two-density package for use in electronic parts and the like. A glass composition for glass fibers excellent in meltability 'spinning properties used in a printed wiring board or the like, a glass fiber formed of the glass composition, and a glass fiber sheet composed of the glass fiber (sheet) [Prior Art] With the development of various information equipment such as mobile phones or personal digital assistants (PDAs), 'resistors, capacitors, integrated circuits (integrated) Circuit) In the trend of high-density packaging technology, many electronic components are packaged on printed wiring boards (also known as printed circuit boards, rigid substrates, and high-density). The situation on the printed circuit board or the printed wiring board) is changing. The printed wiring board is a sheet-like composite material in which an appropriate amount of a resin, a glass fiber, a modifying agent, or the like is mixed, and a through hole (thr〇ughh) for mounting various electronic components is provided. The form is sometimes expressed by using an alias such as a module, a board, a unit, or a package depending on its function or use. For the glass fiber used for the use of the printed wiring board, a glass composition called a glass which is composed of a non-glass (n〇nalkaHglass) has been previously used. This E-glass is excellent in electric insulation, and is excellent in the production of the 201034990 jjuovpifl glass fiber in the peak-melting state, and the material which is excellent in workability such as the processing of the kiln is therefore the most well-known fiberglass. Glass material. Further, for example, in terms of weight percentage in terms of oxide, the E glass contains 52% to 56. /. SiO2, 12%~16% Al2〇3, 5%~10% B2〇3, 16%~25% CaO, 0%~5% Mg〇, 〇%~2% metal oxide (R2〇), 0.05%~0.4% Fe203, 0%~1.0% & glass material. On the other hand, in recent years, in order to realize the use of a printed wiring board, it is necessary to use a high-frequency wave in order to realize a regenerative electronic circuit. However, at this time, it is emphasized that the printed wiring board is electrically miscellaneous. The transfer speed is inversely proportional to the square root of the dielectric constant (p_ittivity). Therefore, it is necessary to have a low dielectric constant in order to increase the transfer speed. Moreover, the dielectric loss is required to be small, so the dielectric dissipation factor must be small. That is, in the present invention, the electric constant (ε) represents the number of non-factors (dimensionless = imb^r)'. The number of non-caused times correctly refers to the ratio of the dielectric constant of the medium to the dielectric constant of the vacuum. That is, the relative dielectric constant is conventionally expressed as dielectric constant ε). In general, if an alternating current flows into the glass, the glass absorbs energy from the parent current and absorbs it as heat. = The dielectric loss energy received is proportional to the dielectric constant and dielectric loss factor determined by the composition and structure of the glass, expressed as W = kfv2xetand. Here, W represents dielectric loss energy, k represents a constant, f represents a frequency, v2 represents an electric potential gradient, and ε represents a dielectric constant. tanS represents the dielectric loss factor. From this equation, it is understood that the dielectric constant and the dielectric loss factor are larger, and the higher the frequency, the larger the dielectric loss becomes. Because 201034990 2. In order to reduce the dielectric loss, it is required to reduce the dielectric constant and dielectric loss. For the F-number of printed wiring boards, a material for glass fiber with a low dielectric protection factor is required. In the bulletin, it is disclosed that the zeta constant and the dielectric loss factor are used to achieve a dielectric constant of 67 at a room temperature and a low dielectric constant of ε of a dielectric loss factor of Curry-4. Glass frit f. For example, in terms of weight percentage in terms of oxide, the D glass is 74.5% of Si〇2, 3%.3% of Αΐ2〇3, 2ι·B2〇3, 0.5% of Ca0, and 〇·5% of U2〇. 1%% of the glass material of 2〇, 15% of κ2〇' The glass has a dielectric constant of about 43 and a dielectric loss factor of about 10~2〇χ1〇-4. However, although the electrical properties of the D glass are excellent, it has been pointed out that there are various problems in the process of printing a wiring board or a glass fiber. For example, D glass is inferior in meltability to glass as compared with ε glass, and it is easy to break end breaks and the like in spinning, and the production of glass fibers is not easy. Further, since the D glass is structurally weak, the weaving property in the weaving process for forming the cloth form for obtaining the printed wiring board is poor, and as a result, the product yield is lowered. Further, in the printed wiring board using the D glass, there is also a problem that the wear of the drill in the drilling process becomes large, the positional accuracy of the via hole becomes low, and the like. The process is a process of forming a via hole, that is, a via hole for the purpose of not interposing the interlayer of the electronic component lead. In order to solve the problems as described above, a number of issued 201034990 have been made so far. A low dielectric constant glass fiber characterized by containing a glass composition of 50% to 60% by weight of SiO 2 , 10% to 18% by weight, is disclosed in Japanese Laid-Open Patent Publication No. Hei-167759. Al2〇3, 18%~25% B2〇3, 0%~10% CaO, 1%~10%, 0%~1.0% Li20+Na20+K20, 0.1%~1% Fe203. A low dielectric constant glass fiber characterized by containing a composition of 50% to 60% by weight of SiO 2 and 10% to 20% of Al 2 by weight is disclosed in Japanese Laid-Open Patent Publication No. Hei 8-333137. 〇3, 20%~30°/〇B2〇3, 0%~5% CaO, 0%~4% MgO, 0°/〇~0.5% Li2〇+ Na20 + K2〇, 0.5%~ 5% Ti02. Further, a low dielectric constant low dielectric loss factor glass is disclosed in Japanese Laid-Open Patent Publication No. 2003-137590, which is characterized by 0/〇~7% of Li2〇+ Na20 + K2〇, less than 3% of Ti〇2; 〇fif2〇<8〇〇PPm, dielectric constant less than or equal to 5.0 at 1 MHz; It is equal to 7χ1〇·4. However, as long as the present invention has been shown to have sufficient mechanical properties, it is easy to control the production of glass defects such as devitrification. For example, the glass composition 201034990 ^^υονριιΐ of the Japanese Patent Publication No. Hei 10-167759 is successful in reducing the dielectric constant of the glass fiber and the electric loss factor, but exists in the meltability at the initial stage of glass melting. There is a problem that air bubbles are likely to remain in the molten molten glass, and the molten glass cannot be sufficiently formed. Moreover, the printed wiring board is mounted on a large number of electronic devices, but the environment surrounding the electronic devices to be carried by t is various. For example, in today's cars, a large number of _ body circuits are mounted, which are highly prosperous and packaged on printed wiring boards, but require the car to make (4) parts ςς 盛 盛 的 盛 盛 盛 盛 盛 盛 盛 盛 盛Driving reliability. In addition, I have fully ensured the passenger space in the passenger car in recent years, and set the electronic circuit, etc., to the engine room, the engine room, and the periphery of the engine room. The temperature is more south than the previous one, and the temperature change is more severe than before. In addition to the situation in the environment, there is a demand for miniaturization of the size of the mounted substrate. Due to various changes in such conditions, printed wiring boards for automotive applications require more resistance and high through-hole reliability. It is necessary to absolutely green ΐ 较大 under the big fault: due to the connection between the printed wiring board and the package parts, there is a difference in the expansion and tilt, so in the high temperature environment τ in the solder (Fuer) 乂ΐ thermal stress (heat stress ) causes solder cracking, electrical connection, and the like. 26, electricity is not allowed for in-vehicle use. This is a fault in the electronic circuit of the large temperature and the reliability required. Therefore, in order to satisfy such a requirement, it is required to reduce the linear thermal expansion coefficient by reducing the difference in the number of wires of the printed wiring board used for the expansion and the hard part. Therefore, a glass 201034990 fiber formed of a glass material having a lower coefficient of thermal expansion than the E-glass is required. In addition, there is a tendency for the glass fiber to be printed on the wiring board to be thinner, and the glass fiber of the printed wiring board tends to be smaller, but the glass fiber of the printed wiring board tends to be smaller. When it is a so-called "long" glass which has a high spinning temperature and a glass viscosity which does not become large due to temperature change like D glass, it is difficult to manufacture fibers in a limited manufacturing environment with no defects and stable quality. The high-quality glass 'age' with a small diameter is required to make it a "sense" glass that is ambiguously changed due to temperature changes. Japanese Patent Laid-Open No. Hei 8-333137. The glass composition has a tendency to have a higher spinning temperature of 丨 伽 · s, and a "long" glass having a small temperature dependency, which is not suitable for manufacturing fibers. Fiberglass. Further, there is a problem in that when the spinning temperature is simultaneously increased, a large load is imposed on the manufacturing equipment, so that the life of the manufacturing equipment such as a bushing used when the glass fiber is extracted is shortened. The glass composition in the Japanese Patent Laid-Open Publication No. Hei. No. 2,313,759 has the following problems. The spinning temperature is as high as 13 〇〇. Above ,, the service life of the spinning 〇 will be shortened. Further, in the case of producing a glass fiber having a small fiber diameter, the bubbles contained in the molten scallop as a defect tend to cause the glass fiber to be cut when the glass fiber is spun. Further, when the glass fiber containing the spurs in the printed wiring board is mixed as a hollow fiber, through-hole plating intrudes into the hollow fiber, thereby causing a risk of poor conduction. The reliability of the printed wiring board is lowered, which is a problem. When the temperature of the 201034990 s_ is higher than that of the D glass, it is necessary to apply a large amount of energy during the melting, and the bubbles do not all float out during the smelting to generate a large amount of hollow fibers. More. In order to reduce the number of bubbles in the fused glass, it is effective to use a arificious acid such as arsenious acid and antim〇ny tri〇xide. However, these clarifying agents are also environmentally hazardous substances, and it is considered to be a problem if the component sheets used in the electronic machine g contain these elemental components. SUMMARY OF THE INVENTION An object of the present invention is to provide a molten glass which can easily obtain homogeneity due to a low melting temperature, which is excellent in spinnability, high chemical durability, and high density. A composition for a glass fiber having a low dielectric constant and a low dielectric loss factor required for a packaged printed wiring board and further having a low coefficient of linear thermal expansion, by spinning the glass of the glass fiber composition The obtained glass fiber-dimensional, and a glass fiber sheet composed of the glass fiber. The inventors of the present invention have repeatedly conducted a large number of difficult problems associated with the use of a printed wiring board capable of reliably overcoming a high-density package, and have been able to stably produce a glass fiber composition related to a glass fiber having a small fiber diameter. In particular, regarding the action of the alkaline earth metal element in the glass composition, the above-mentioned various problems 4 are solved by adding the components in a predetermined amount, and it is possible to realize a glass fiber composition which can exhibit excellent properties not hitherto and can be made. Since the glass fiber composition is formed into a glass fiber having a small fiber diameter, the glass fiber composition of the present invention is disclosed herein. The glass composition for glass fibers of the present invention is characterized in that it contains 45% to 65% of SiO 2 and 10% to 20% of Al 2 〇 3, 13 ° / ❶ 25 25 in terms of weight percentage in terms of oxidation 10 201034990 33 U 69 pifl. % B2 〇 3, 5.5% to 9% of MgO, 0% to 10% of CaO, 0% to 1% of Li20 + Na20 + K20, SrO, and BaO. Here, 'the weight percentage in terms of oxide is 45% to 65% of SiO 2 , 10% to 20% of Al 2 〇 3, ～25 ° / 〇 ugly 203, 5.5% to 9%]\^ 0, 〇 ° / 〇 ~ 10% 〇〇, 〇 % ~ 1% of Li20 + Na20 + K20, SrO, and BaO, refer to the internal content as described below. That is, when the elemental components constituting the glass are expressed in terms of oxides by various analytical methods such as chemical analysis and machine analysis, the glass composition is expressed as: the Si 〇 2 component is in the range of 45 wt% and 65 wt%, Ab The 〇3 component is in the range of 1% by weight and 20% by weight, the B2〇3 component is in the range of 13% by weight 裘25% by weight, and the Mg 〇 component is in the range of 5% by weight to 9% by weight, and the CaO component is less than or equal to The weight ratio of 1 〇, the composition of the 〇2〇 component, the Na2〇Ο component, and the 〇2 component are less than or equal to 1% by weight, and further contains a SrO component and a Ba〇 component. Further, in the glass composition for glass fibers of the present invention, in addition to the above, the weight percentage in terms of oxides is expressed as 0.01% to =0% by weight, and bubbles in the molten glass can be reduced. The number of hollow fibers is reduced, so that glass fibers having high homogeneity can be obtained. Further, in the glass fiber composition for glass fiber of the present invention, in addition to the above components, in terms of weight percentage in terms of oxide, Sr〇 is 0.1%. 201034990 jjuoypul 10% BaO is Q.1% to 1G%. , it becomes the glass dissolution, the job is new (four) low Chen _ glass axis money, so it becomes Ϊ == 璃_融' and the glass turn (five) water and acid resistance will not become low, that is, the same as the escape, so-called In terms of weight percentage in terms of oxide, Sr0 is 〇1% to 10%, and Ba〇 is 〇1% to 1% by weight, which means that the composition of the glass composition is represented by 〇, in addition to the composition of the above glass composition. The SrO component is from G1 by weight to 1 G% by weight, and the BaO component is 〇·ΐ by weight to 1% by weight. Hereinafter, the reason for limiting the content ratio of each of the above-mentioned __fiber_lang compositions will be specifically described. The bismuth component is a main component of the glass composition of the present invention, and the structural strength of the glass becomes larger as the content of the 12 component of the glass composition increases. Propensity. If the knot degree of the glass becomes large, the chemical durability of the glass is also improved: the glass composition for glass fibers having high performance in terms of dependence is improved to a certain extent. In order to maintain the strength of the glass structure in a sufficient state 'S has a stable quality', the content of which component must be at least greater than 45 wt%, and more preferably 48 wt% or more. On the other hand, if the content of the qing component in the glass composition increases, the high-temperature miscellaneous value of the solution = glass becomes large, and the kiwi syllabary (four) fusion method produces the surface composition with high efficiency and homogeneity. High-priced equipment. Moreover, the molding temperature at the time of forming into a glass fiber also becomes high. Therefore, there are cases where restrictions are imposed on equipment management at the time of manufacture. In order to accommodate 12 ιίΐ 201034990, it is easy to use it. When it is melted, it does not remain in the homogenization of the vitrification reaction. It does not require excess heat energy in the glass county, and it is guaranteed to manufacture glass. The spinning property of the fiber at the time of the fiber, the content of the shell of the J Si02 component is not less than or equal to 65%. Ο Ο a] 2〇3 component is an effective component for realizing the chemical stability and mechanical stability of glass. There are also crystallization and phase separation of crystals in the glass by only a proper amount contained in the glass. The effect of the generated effect, but the right side 3 will increase the viscosity of the molten glass. If the content of the glass component is less than 1 G weight percent, the phase separation of the intimacy is not good. The deterioration of the axial beam is caused by the deterioration of the acid resistance of the glass fiber of the game, which is not preferable. This eight f shows dissolution, and the glass separation is a plurality of glass phases of 2 or more. On the one hand, the right composition makes the glass composition #Al2〇3 component, and the content of other components, especially the 汹2 component, is relatively resistant. , the bad influence, so the content of the component of the p component is 1% by weight, preferably 18% by weight or less, at 16% by weight, and the better is less than the best 疋 夏Equal to 15 weight percent. For the beans 2 3 = ^ and S1 〇 2 ingredients 'in the glass network structure into a warm sticky: wood is: there are: the same as increasing the high S' of molten glass: and her role: lower formation of the formation The dielectric of the glass, and _ (four) high temperature pure ^ B203 composition containing I, η 壬 θ right glass, the composition of the W knife ^ less than 13 weight percent, there are the following: 13 201034990 ^JUO^pnl It is difficult to maintain the dielectric constant of the glass at 6 小于 or less, that is, the temperature of the molten glass at '° coffee.s' is not the temperature at which the spinnability of the filament is less than 13 _. On the other hand, if the amount of the content 4 in the glass composition is too large, the amount of evaporation of the n component in the smelting is increased, and it is difficult to maintain the molten glass in a homogeneous green color and a 23 shape. Further, if the content of the Β2〇3 component is too large, it is sensible, and the phase separation property of the molten glass is deteriorated. In this case: Easy + Evil If the 仏03 component in the glass composition exceeds 25 weight percent, the acid resistance and phase separation are deteriorated, which is not preferable. The present Mg 〇 component is a component having a function as a fusmg agent for immersing the glass raw material, and is effective for lowering the high-temperature viscosity corresponding to the degree of 丨〇2·0 dpa · s. It makes the glass good when it is melted, which helps to make a homogeneous glass. Moreover, it has a function of lowering the temperature of $dPa.s and shortening the glass, so that the productivity is very good, and it is possible to efficiently produce glass fibers having a small fiber diameter. However, in the glass composition, in order to make Mg0 function effectively, the spinning temperature, i.e., the high temperature viscosity in the vicinity of HP dPa·s, is lowered, and it is necessary to set the MgO component to 5.5 wt% or more. On the other hand, when the content of the MgO component in the glass composition is too large, the phase separation property of the molten glass becomes high, and the acid resistance is deteriorated. Further, the dielectric constant also rises, so from this point of view, it is not preferable that the MgO component exceeds 9 weight%. In the same manner as the MgO component, the CaO component has a function of lowering the viscosity of the molten glass corresponding to the temperature of 1〇2.〇dPa·$, and the ratio of the dielectric constant increases in the component containing the 5 alkaline earth metal element. The smallest. However, ο Ο 201034990 33069pifl If the glass composition contains a large amount of CaO component, the acid resistance of 丨8 4 _ is lowered. Moreover, the dielectric of the glass often becomes south and the glass increases and becomes larger. Therefore, if the composition of Ca0 is good. The percentage of ιυ重I is not related to the metal oxide component expressed by the conversion of Li2〇 component, Na2〇 component or κ2〇 component = fc: conversion: when heated in the state Becoming a ruthless smother::::::= f_2. : When the amount is increased, the value of the dielectric loss factor of the glass 増: the upper limit of the glass 1 is at most 1 weight percent. ϋ S S S S S S S ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ig ig ig ig ig ig ig ig ig ig ig ig ig ig ig ig ig ig ig ig ig ig ig ig ig The role of nearby points. However, the _ component is a component that has the effect of increasing the phase separation property of the granules of the granules, and the effect of the composition of the glass-based Sr0 component becomes more conspicuous. greater or equal to. ·〗 〖weight percentage. Another: the content is too much; when the glass composition is used, if the second point of view: words, the composition of the ... ..., the ratio of 100%. When the glass melts, if the phase separation 201034990 jiuoypnl deteriorates, the melted glass is separated into an acid-rich phase and a poor acid-resistant phase. At this time, the acid-resistant phase determines the acid resistance of the glass fiber, so the acid resistance of the glass fiber Sexuality is worse, so it is not good. In the same manner as the SrO component, the Ba〇 component lowers the viscosity of the molten glass corresponding to the degree of i〇2.g dPa·s, and further reduces the spinning temperature in the vicinity of 10^dPa·s of the molten glass. The component of action, but its effect is not as good as that of Mg〇 or CaO. However, the Ba 〇 component is a component which has a function of suppressing deterioration of phase separation property due to an increase in Mg 〇 or CaO component and a consequent decrease in acidity of the glass, and is used for the purpose of the present invention in the same manner as the component (10). Essential ingredients. The Ba 〇 component is also the same as the Sr 〇 component, and the effect of the inclusion becomes more pronounced, and the content of the glass composition is 0.1% by weight or more. On the other hand, if the content is too large, the liquidus temperature is deteriorated, and it is difficult to produce a glass fiber having a small fiber diameter. It is preferable in this respect that the surface contains a maximum of 1% by weight. The glass having a long stomach is a glass having a small viscosity dependence on the temperature change of the crucible, and it is difficult to solidify into a fiber by cooling. In this case, the Sr〇 component and the Ba0 component are likely to form a crystal, and if the Sr0 component is contained in the composition of the second glass, it is easy to precipitate if the Ba0 component is contained, and it is easy to precipitate (4), and the glass (6) has a high night temperature. tendency. 5 (bushing nozzle), which causes the liner to be cut during spinning, which is a problem. However, if the glass of BaO is as high as the composition of the BaO, the glass composition enters Sr0.Si〇2 and contains SoP crystals. Therefore, it is desirable to combine the glass composition with the Ba0 component, ie, Ba0 is a gas stagnation that is a defect in the bubble. 〇1 is called a clarifying agent for the thing of the brother and is added in an appropriate amount. However, the icing of the Ce 〇 2 component is more obvious as the weight in terms of oxide. t In the case of %, it is more preferable that the component of 4(10)2 is added too much in a large amount, and there is a case where the shirt is smashed and broken. = The percentage by weight of the compound conversion should not exceed 5% = = stable quality, the upper limit is preferably at most 4%, and the better 疋 is at most 2%. If it is the best addition amount, the fiber is not hollowed out (_ side (four)). In the glass composition for glass fiber of the invention, it is possible to add various components in addition to the above-mentioned components, and to the extent that the performance of the glass-filled composition for glass fibers of the present invention does not greatly affect. When the components which can be used as the constituent components of the glass composition for a glass of the present invention are specifically described as three examples, they may be contained in a weight percentage of 3 or less and contain zr〇2, P2〇5, and Fe2〇3. , s〇2, cl2, F2, La2〇3, or 3, and rare earth oxides such as AO3 (track a1111 〇Xide) 17 201034990 4 In addition to the components, it may also contain a weight percentage of 0,1 /° Oh! ingredient. For example, various trace components such as Cr203, H20, 〇H, H2, ca, (7)^ kiss, and so on are suitable. Further, in the glass composition for glass fibers of the present invention, the performance of the glass composition for glass fibers does not produce a large amount of glazing material. For example, it may contain a platinum metal element such as a maximum __, and 0S, that is, a content of a metal element in terms of a weight percentage, and a content of a right-handed n]0/A Ο element. 3, 3, and the maximum of 0.1% of pt, Rh, and 0s are turned over. Further, in the case of the glass fiber composition of the present invention, the percentage of the oxide-converted amount indicates the ratio of sr〇 and Ba. Jujongjin Wei compound for g C 25%, SrO and BaO's hinged LV LV in the mountain a willing to measure the value obtained in 0.15 is the oxide phase conversion of the glass phase separation, avoiding the two can be suppressed When the melt is melted, the spinning temperature is lowered, and the resistance to enthalpy is lowered, and the precipitation of the crystal and the phase separation ' ^ ' become less dangerous in the glass state when (n〇nh〇n〇wglass) ^ Q is melted. The spun glass becomes heterogeneous. The temperature dependence of the viscosity near the A degree is large, (4) 2: 25%, and the mouth of the SrO and Ba0 is 10%~, and the mouth is divided by the alkaline earth. In the range of 〇.15 to 0 50, the value of the metal oxide is in the range of 〇15 to 0 50, which is the sum of the weight percentages expressed in terms of Sr and Ba, divided by the oxide as the soil test. The value obtained by the total weight expressed by the weight percentage of the oxide of Mg, Ca, Sr, and Ba of the element is in the range of 〇15 to 〇5〇. When the weight percentage of oxides is expressed, the total amount of the earth metal oxides of Mg〇, CaO, SrO = and BaO is less than 1% by weight, it is difficult to obtain a sufficient homogeneous state at the initial stage of glass melting, and melting When the viscosity of the glass in the 岫 state is high, the molding temperature is excessively increased, and the spinnability of the glass fiber is lowered. On the other hand, when the total amount of the alkaline earth metal oxides of MgO, CaO, SrO, and BaO is more than 25%, it is a problem in terms of acid resistance and phase separation. In addition, when the value obtained by dividing the total amount of SrO and BaO by the total amount of the alkaline earth metal oxide is less than 15, the content ratio of MgO and CaO increases, and the phase separation property of the molten glass tends to increase. Large, and the dielectric constant is also high, so it is not good. On the other hand, when the value of Ο σ of Sr 〇 and Ba 除 is divided by the total amount of the measured metal oxides, the value exceeds 〇·50, and the dielectric constant becomes too high. Further, the spinning temperature, i.e., the y becomes high, and the glass develops in the long direction, so that the spinnability is lowered, and it becomes difficult to produce a glass fiber having a small fiber diameter. Regarding the glass composition for glass fibers of the present invention, in addition to the above, if the dielectric constant at a step rate of 1 MHz is 6.0 or less and the dielectric loss factor is 20 χ 1 or less (Γ4, the dielectric loss of the printed wiring board) It is better to be smaller. 19 201034990 In addition, if the frequency is _Z, the median number is used; ^ and the object, in addition to the above plate dielectric loss is further reduced, the printed wiring of the = = = = In addition to the above, if the volume resistivity lGgpA is equal to 13Q.em, the glass composition for glass fiber exhibits stable performance when used as a printed wiring board or the like. Further, with respect to the glass composition for glass fibers of the present invention, the temperature Ty of the above-mentioned 10 dPa.s is less than 1300. 〇, if the value obtained by subtracting the temperature of 1〇7·6 dPa·s from the y is in the range of 3〇〇t:~45 (rc, the spinning device and the spinning method of the glass fiber are not used) It is preferable to carry out the glass fiber by efficiently making a large change. If the temperature Tx of 1 〇 7.6 dPa · S is subtracted from the temperature Tx of 10·0 dPa · S and the value obtained is 45 or more (TC, the viscosity of the glass becomes long, so if the fiber diameter is to be small, the fiber diameter is small. In the glass fiber, the molten glass extracted from the tip end of the nozzle on the liner is deformed under the nozzle, that is, the meniscus becomes unstable, and stable spinning properties in which the fiber diameter is not uniform are obtained. On the other hand, if the temperature Tx of 1〇7·6 dPa·s is subtracted from the temperature Tx of 10·10 dPa · s and the value is less than or equal to 300 Τ:, the viscosity of the glass becomes too short. Therefore, there arises a problem that a reasonable range for setting other manufacturing conditions for obtaining a predetermined fiber diameter, such as a drawing speed and a cooling condition, becomes small, and management of the fiber diameter becomes difficult. The glass fiber of the present invention is composed of the present invention. Glass fiber is composed of glass composition 20 201034990^, and the average diameter of glass fiber is 3 to 72. It is suitable for high density and thinning: ρ brushing, etc.... greatly improved by fine fiber such as straight =(4) 复合 Μ Ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ΐ ΐ ΐ ΐ 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于The treatment environment leads to such an environmental aspect, and therefore is not preferable. On the other hand, when the average value of the diameter of the glass fiber exceeds 7.2 _ ^ ' even if the glass fiber formed by the glass composition of the present invention is not used, : It is possible to obtain a stable quality glass fiber with a low-complexity tf (four) glass by the self-first shot box, so that there is a lack of economical advantages. The glass fiber of the present invention is made of the glass fiber of the present invention, and the rest of the average is recorded in the range of 31 #=~6.5 (four), more preferably 32 (four) of the fan's further preferably 3.3 //m ~5.5 _ range, Further preferably, 3.4 /m to 5.2 is preferably 3 8 4 8 am °, and as for the glass fiber of the present invention, if the hollow fiber is equal to or less than 2 / 1 G 10,000 filaments (fllamem) When used in the use of the printed circuit board 2010 201090390 33069piil wiring board, it is possible to obtain a highly reliable printing machine. The hollow fiber is less than the equal force. 2 / 100,000 filaments are in the table 3 1 million filaments. The number of hollow fibers is less than or equal to 2. The number of hollow fibers is measured by immersing glass doth in an immersion liquid adjusted to a refractive index of glass fibers, _ (one) times the transmitted light) Observation was carried out, and the measurement of the medium dimension in the warp of the glass cloth was carried out, and the value was divided by the number of filaments to be observed == times, thereby being easily obtained. 5. To increase the K) and the glass fiber of the present invention, in addition to the above, is used in the use of _ a ', especially less than or equal to _ = brush wiring board, the defects can be obtained: ==== :—Saki's = broken is equal to °·_/m, which means that the number of bubbles in “r贲, 4 is less than or equal to! For example, for all the gas with a bubble length of lmm or more = 中 mirror break: rate The glass fiber is easily measured by immersing it in the secondary liquid which is adjusted to be the one. In addition to the above, if the bubble contains a good glass, j, ^ _ g glass can achieve higher quality, and more than 5: equal to __g glass, gas in the bevel. The bubble content ratio indicates that the glass fiber having a weight of 100 g may also be a glass fiber coated with a coating agent imparting a desired physicochemical property to the surface. Specifically, it may be a glass fiber coated with a sizing agent, an antistatic agent, a surfactant, an antioxidant, a film forming agent, a coupling agent or a lubricant. If exemplified is a silane coupling agent that can be used in the surface treatment, there are: 7-aminopropyl triethoxysilane, phenyl·γ-aminopropyl three N_phenyl-7-aminopropyl trimethoxysilane, glycidoxypropyl trimethoxysilane; 夕 _glyCjd〇xypr〇pyl ❹ trimethoxysilane, r-mercapto acryloxypropyl three 7-quot;-methacryloxypropyl trimethoxysilane, aminoethylamino-aminopropyl 'trimethoxysilane, 10,000-(3,4-epoxy group) Cyclohexyl)ethyltrimethoxysilane (N-y5-(N-vinylbenzylaminoethyl)·γ-aminopropyltrimethoxy sylvestre • N-vinylbenzylaminoethyl - γ-aminopropyl trimethoxysilane hydrochloride, r-chloropropyltrimethoxysilane oxime (?" -chl〇ropropyl trimetitioxy silane ), 7"_ Weipropyl triterpenoid T-mercaptopropyl trimethoxysil Ane), vinyltriethoxysilane, etc. may be appropriately selected depending on the type of resin to be used in combination with the glass fiber. Regarding the glass fiber of the present invention, in addition to the above, the coefficient of variation of the glass fiber diameter obtained by multiplying the standard deviation of the fiber diameter by the average value of the fiber diameter (C〇efflcient 〇f Vai> iattkm Γ A plurality of glass filaments having a CV value of 10% or less are tangential (ch〇pped 23 201034990 33069pifl strand), and a yarn (yarn): for use on a broken glass fiber having a smaller diameter of the dimension The value exceeds 1〇%. If the glass fiber fails, it is not good.

The glass that is made up of 2 thousand ί and multiplied by 1 〇 0 is used to cut the yarn. Incidentally, the / ^ + mean value calculated from the measured value of the fiber's coarse glass fiber is controlled by the glass forming device of the _ mode nozzle, and the temperature of the ϋ γ / heat-resistant spray nozzle is determined. The conditions of the atmospheric temperature, the nozzle enthalpy, the length of the nozzle, and the speed at which the glass filament is withdrawn are selected so that the optimum conditions for the composition of the glass fiber and the glass fiber can be made into the length of the glass of the invention. Cut I, fine yarn or thick # can form a uniform-diameter broken material in various forms. In the use of 24 201034990 iiuoypifl printed wiring board, the glass cloth that has been unwoven and relaxed is used to suppress the formation of through holes. It is preferable to change the position of the hole due to the offset of the tip end of the drill in the hole manufacturing process, thereby improving the hole position accuracy. Further, the glass fiber of the present invention can be produced by any production method if the desired property b can be achieved. For example, various methods such as a direct melt method (DM method: direct melt method) and an indirect forming method (MM method: marble melt method) can be employed depending on the application and the production 1. In other words, the glass fiber of the present invention may be a glass fiber obtained by drawing a glass fiber from a bushing including a heat-resistant nozzle to obtain a glass fiber of a predetermined diameter.

First, a predetermined amount of natural mineral glass, chemically synthesized surface, and other types of glass raw materials are weighed in g units of three decimal places to make each glass composition of Table 1. Next, the glass raw material mixed batch (b^tch) mixed in such a manner that the plurality of raw materials are in a homogeneous state is prepared, and the glass raw material mixed batch is put into a platinum crucible having a sweetness of 5 〇〇CC. Inside. Secondly, in the indirect heating electric furnace, the platinum crucible which is put into the raw material=batch material is heated in the atmospheric environment for 155 〇t: heating for 5 days, so that the glass riding mixed batch chemical reaction at high temperature becomes molten. glass. In order to make the molten glass in a homogeneous state, the molten glass is stirred by a heat-resistant stirring bar during heating and melting. In this manner, the molten glass in a homogeneous state flows out into a predetermined fire-resistant template, and the sHpcasting is in a regular shape, and an annealing treatment is performed in the slow cooling furnace to room temperature. A glass molded body used in a test or the like is obtained. 〇 ^ The silk body was obtained in this way, and various physical properties and the like of each of the glass compositions of the examples of the present invention were measured in the following order. The results of the measurements are summarized in Table 1. Regarding the measurement of the linear thermal expansion coefficient, the SRM-73 SRM_738 of the National Institute of Standards and Technology (NIST, National Institute of Technology) is used as a standard sample of the known linear thermal expansion coefficient, and The well-known linear thermal expansion measuring machine that has been corrected has a benefit of 30. (: The average linear thermal expansion coefficient measured in the temperature range of 380 °C is 201034990 j^uu^pifl number. The lower the value of the thermal expansion coefficient of this line is, the expansion of the glass fiber changes even when the temperature changes greatly. As a result, the reliability is improved in relation to temperature fluctuations when the printed wiring board using glass fibers is mounted on an electronic device. The temperature of 1〇3, 〇dPa·s indicating the high-temperature viscosity of the molten glass is measured. (Ty), each glass sample crushed in such a manner as to be appropriately sized is put into an alumina crucible and reheated, and after being heated to a molten state, the glass is pulled by the platinum ball. Each value is calculated by interpolating the viscosity curve obtained by multiple measurements of the viscous values measured by the method. Moreover, the value of Ty-Tx in the table is from the equivalent of 1〇3·0 dPa. The value of the temperature corresponding to 1〇7·6 dpa·s, that is, the softening point is subtracted from the value of s. The measurement of the softening point is a value measured by the method of astm^3^^. The smaller the value of -Tx, the higher the viscosity of the viscosity = the larger the 1 glass is shorter The shorter the broken glass, the easier it is to melt and the state becomes solidified due to the seven parts. Therefore, it is produced after the spinning of the molten glass, even if it is a phase_cooling condition, ί = ^ 疋' and can be produced without cutting. Glass fiber. The viscous N of the glass fiber: the longer the sturdy moon, the longer the meniscus becomes, and the inconvenience of the production of the sturdy cooling conditions, etc. In the case where the glass molded body is cut into a surface area of a predetermined range, the material is finely divided so that the particle size is in the range of 300 to 500, and the state of Um is filled in the platinum potential. //, there is a rich volume density 奋 奋 (10) ' put into the highest temperature set to 1250 34 201034990 jjuuypifl °c indirect heating type temperature gradient 燐Μ small _ plus _ 4 彳 = ^ in the atmosphere Out, place cold (4) to make ^ together with τ * , ^ to determine the liquidus temperature TL. The value of Ty-TL in the table is subtracted from the equivalent of 1〇3 〇·· The value of the temperature. τ, / dish and spoon - the greater the value of the waiter ~ 玎, then The crystallization of the scale operation is not easily precipitated in the vicinity of the twist, so that the spinning state can be ensured. In order to increase the value of n, the temperature Ty corresponding to the spinning temperature of 1〇3.〇dPa·s may be increased, but if this is the case, the amount of (four) required for the sense of melting and melting is increased to cause manufacturing. The cost rises and the problem of shortening the equipment of the bushing device (4). The volume resistivity at 150 C is a value measured at 15 G ° C according to ASTM (f) (iv). The higher the volume switching value, the better the printed circuit board for high-density packaging, and the stable electrical insulation performance. For the measurement of the dielectric constant (ε) and the dielectric loss factor (tan d ) at a frequency of 1 MHz, a glass coupon of 50 mm x 50 mm x 3 mm was processed using a slab 200 sand paper. A sample having a thickness of 3 mm on both surfaces was ground. The measurement was carried out in accordance with ASTM D150-87 by using a 4192A impedance analyzer manufactured by Yokogawa Hewlett-Packard, at room temperature. For the measurement of the dielectric constant (ε) and the dielectric loss factor (tand) at a frequency of 1 GHz, the short-circuited dielectric resonance crying method according to JIS R1627:1996 is used by using Agilent ( Aglient) network analyzer (netw〇rk 1 35 201034990 o^uoypifl analyze〇, obtained by measuring at room temperature. The smaller the loss factor, the composition is: the number of cranes and When glass fiber is used, the dielectric loss of the printed wiring board is changed to the surface area of the application, and the surface area of the predetermined range is removed by removing the finely pulverized material, so that the particle size is in the range of 3 Å.

Then, after the acid treatment, the weight value is decreased with respect to the weight value of the originally-invested glass. Perform measurement 1. The resulting reduction rate measurement The value is greater than or equal to 30%, and it has been confirmed that in the acid test, a sample of the reaction product is formed on the surface of the glass due to a bribe. The acid resistance of the glass is lowered, and it is judged as X. The other sample is determined to be caused by the formation of a reaction product due to the reaction of the rot #, and the acid treatment may be performed in the plating treatment or the like performed in the process of producing a printed wiring board using glass fibers. The risk of lowering the yield rate is hindered by ensuring a homogeneous treatment state. The following can be clarified according to the above test.

However, the content of SiO 2 is high, so the temperature of l 〇 3.G dPa · s which is equivalent to the spinning temperature becomes a value of up to 1,336 °C. When the glass fiber is spun for a long period of time, deterioration of the manufactured equipment is caused, and there is a problem in economy. Further, the temperature Tw of the standard l 〇 2G dPa · s which becomes the melting temperature is 1600 ° C or more, which is extremely high. Therefore, bubbles are likely to remain in the glass when the glass is melted, and the value of Ty - Tx is 526. (: It is a long glass, and there is a problem in spinnability.) Regarding the glass composition of sample No. 103 of the comparative example, the ratio of the total amount of SrO to BaO to the total amount of the soil metal oxide exceeds 〇5.1〇3.0 dPa·s The temperature exceeds 1400. 〇, the value of Ty_Tx is 53 generations, which is a long glass, so it is difficult to make glass fibers with a small fiber diameter and melt. The melting and spinning of glass There is a problem in silkiness. The temperature Tw of 1〇2,0 dPa · s is also high' and does not contain Ce〇2, so the bubbles are easily left in the glass when the glass is melted. Therefore, the composition of the glass cannot be made hollow. The number of fibers is 20,000 long faces, and the dielectric loss factor is as high as 0.0025 at a frequency of 1 MHz, and the dielectric loss is as high as G_8 at a frequency of 10 GHz, so there is a large dielectric loss and transmission. The problem of slower speed. The glass composition of the sample No. 1〇4 of the comparative example is a glass composition containing no Sr〇 and BaO, and the total amount of Sr〇 and Ba〇 is relative to the total of the soil test emulsion. The ratio of the quantity is as low as 0.00. Therefore, the temperature production of 103·〇dpa·s is 1332. The temperature of the standard l〇2.QdPa.s of the melting temperature is also as high as 1568〇C or !568. When the glass is smelted, the residual gas is more than the gas: 43 201034990 The phase separation is confirmed when the glass melts. In the acid resistance test, the reaction product which reacted with hydrochloric acid was confirmed, and there was a concern that etching treatment was performed in the process of printing a wiring board. The volume resistivity of 1 〇gp was 12.7 Ω · cm ' as a printed wiring. The electrical reliability of the plate was low. Regarding the glass composition of sample No. 105 of the comparative example, the ratio of the total amount of SrO to BaO to the total amount of the alkaline earth metal oxide was as low as 〇〇5. The glass of .105 is a glass composition with a dielectric constant of up to 6.10' at a frequency of 丨MHz and a dielectric constant of 6.2 at a frequency of 10 GHz. Moreover, the dielectric loss factor of the sample at a frequency of 〖MHz It is also as high as 0.0025, and the dielectric loss factor is also as high as 0.0127 at a frequency of 1 GHz, so there is a problem that the dielectric loss becomes large and the transmission speed becomes slow. Moreover, significant phase separation is observed when the glass is melted, and this significant fraction is obtained. Phase As a result of the acid resistance also causing adverse effects, it is a glass composition that confirms the problem. ~West, according to the examples shown above and a series of comparative examples performed in the comparative example, it is clear that the glass fiber of the present invention is composed of glass. The glass having a small fiber width in the material-sealing plate is also excellent in spinnability in the production of glass fibers, and can provide a stable quality glass fiber in the production of the glass fiber. As above, it is not intended to limit the knowledge of the invention in the technical field of the invention, and it can be modified and retouched without leaving the invention. Therefore, the application of the drawing is simple. Following the definition of _. 44 201034990 None.
