Known technical description: Copper-clad laminate is the base of printed circuit boards. It is made of prepreg and copper foil (one on top of the other) by heating and pressing. (The prepreg is an intermediate product obtained by impregnating a substrate, such as paper and glass cloth with thermosetting resin.) The manufacturing method of a laminated sheet with copper foil on both sides is to press between two imprint plates of a press. Copper foil, prepreg, inner layer circuit, prepreg, and copper foil (arranged in the stated order). In the pressing operation, it is generally customary to insert a member (called a release plate) between the imprint plate and the copper foil to prevent the irregular surface of the imprint plate from being transferred to the surface of the copper foil and prevent the imprint plate and the copper foil from sticking . An example of a release plate is that both sides of it are coated with release material to avoid the prepreg powder produced when the laminate is laminated or the prepreg resin is melted.

Invention Explanation (2) Sticky (hereinafter referred to as "releasability"). The release plate (coated with release material) must have the following characteristics. (1) Long-term repeated operation has good releasability. (2) Good heat resistance (or can withstand heat and pressure). (3) Good resistance to transfer (or prevent the pattern of the internal circuit from being transferred to the release plate, and prevent the irregular surface from being transferred to the product's copper foil). (4) Good flatness and rigidity, and can extrude uniform laminations. The following materials can meet the above requirements, but they each have their disadvantages. (1) Stainless steel (U SU) plate, used without release material alone. The problem in this case is that expensive U S U leads to increased production costs, and the stainless steel plate loses its flatness after repeated use, unless it is polished uniformly. (Polish and clean before use). (2) A stainless steel (SUS) plate is used together with a release paper or film as a release material. The problem in this case is that SUS is expensive and the release paper or film cannot be reused. Stainless steel plates need to be polished and cleaned before reuse. (3) Aluminium sheet, use no release material alone. The problem with this case is that the aluminum plate is expensive and cannot be reused. (4) Aluminum plate or foil is used together with resin coating as a release material. The problem in this case is that the material cost is too high. Even though aluminum foil can be reused, it wrinkles (and therefore becomes less flat). (5) The intermediate layer is used together with a release paper or film as a release material. The problem in this case is that the material cost is too high. The release film can no longer be used, and it is easily wrinkled, losing its flatness.

Note I Binding Binding Printed by the Intellectual Property Bureau Employees Cooperative of the Ministry of Economic Affairs 590885 A7 __B7 5 3. Description of the invention (3) (Please read the precautions on the back before filling out this page) The problem of traditional technology is as described above, that is, the use of film, paper or foil for release purposes lacks flatness and therefore cannot be used for manufacturing A good-looking copper-clad laminate is required. In addition, it is too thin and difficult to handle, and it cannot be reused. (It was originally designed to be discarded after use.) On the other hand, the mirror-finished stainless steel plate has excellent flatness; however, it must be polished and cleaned before reuse. This results in increased manufacturing costs. The present invention is directed to the above problems. The object of the present invention is to provide a surface-coated steel sheet which can be reused and has excellent characteristics in various aspects such as transfer resistance, surface smoothness, heat resistance and releasability. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs The present invention covers plated or unplated steel plates with a resin coating film. The resin film may be epoxy resin, phenolic resin, polyimide resin, polyimide , Ketone resin, all aromatic polyester resins, unsaturated polyester resins and silicone resins as the main component, the characteristics of this resin coating is that when the surface temperature of the steel plate is 180 ° C, and The contact angle of the gear oil (with the viscosity of I SO VG460) is not less than 15 degrees. The present invention requires that the resin coating layer has good oil repellency (from the viewpoint of the contact angle specified above), so that it exhibits good releasability at high temperatures. According to the present invention, the resin coating film should have a pencil hardness of 2 Η or more (J I S KK 5400), and 俾 ensure the smoothness of the copper foil after pressing. According to the present invention, the surface roughness (Ra) of the resin coating film must not be greater than 0 · 5 microns (the arithmetic average measured according to JIS B0601). The paper size is applicable to the Chinese National Standard (CMS) A4 specification (210 X 297 public ^ 1 590885). A7 B7 5. Description of the invention (4). Otherwise, its surface irregularities will be transferred to the copper foil, which will hinder the formation of accurate printed circuit boards. According to the present invention, the resin coating film may contain silicone resin and / or Fluoro resins (as release agents) and surface roughening agents are preferred. They are helpful for releasability and protecting copper foil from contamination. According to the present invention, the amount of the resin coating film formed is 0.5. -8 · 0 g / m 2 is preferred. According to the present invention, the yield point of the plated or unplated steel sheet is not less than 200 N / mm2, and / or the tensile strength is not less than 30 ON / mm2. Example Description The present invention covers plated or unplated steel sheet with a resin coating film formed on it. When used as a release plate, the steel plate is preferably an aluminum plate. The latter has a high thermal conductivity and can efficiently remove heat from the plate. Conducts to the stack, but moves relative to the copper foil of the stack during pressing Because it has a larger expansion coefficient than copper foil. On the other hand, the steel plate has a suitable thermal conductivity and a thermal expansion coefficient of 12.5x 1 0_6, which is very close to the thermal expansion coefficient of copper foil 1 7 XI 〇_6. Therefore, during the pressing Does not move relative to copper foil. Depending on the type of resin coating film used, stainless steel plates (with good corrosion resistance) or ordinary steel plates with or without single metal or alloy plating can be used. There are no special restrictions on the plating method. Galvanized or galvanized steel is preferred. Electroplating is performed after chromate treatment and before resin coating. The chromate film can improve the adhesion of the resin coating film and has an antirust effect.

Description of the invention (5) It must be oil-repellent when warm. This requirement is based on the present invention Found that oil repellency at high temperature will greatly affect releasability at high temperature. By measuring the contact angle of the resin coating layer under specific conditions, the desired oil repellency can be easily established. Determination of the contact angle of resin coating The method is to place a drop of gear oil with viscosity class IS 0v G 4 60 on the resin coating film. The gear oil should be limited to viscosity that can affect the measurement of contact angle. To meet this requirement, the gear oil is, for example, "Daphne of Idemitsu Kousan" Super Gear Oil 460 ". Its dynamic viscosity is 459 · 9mm2 / s at 40 ° C, 30 · 8 5 mm 2 / s at 100 ° C, flash point 2 7 4 ° C, 1 5 t: density at time 0 · 9 0 2 8, total acid number (total acid number) 0 · 3 8 mg KOH / g. The contact angle is measured at 18 Ot: or at a surface temperature of 180 t of the coated steel sheet. Gear oil drops were placed on the surface of the resin coating film, and the contact angle was measured using a contact angle table (such as Model CD-DT-A from Kyowa Kaimen kagaku). The gear oil contact angle required by the present invention cannot be less than 15 degrees; otherwise, the resin coating film lacks oil repellency and has poor releasability. According to the present invention, the pencil hardness of the resin-coated film cannot be lower than 2 Η (determined in accordance with J I S KK 5400): otherwise the resin-coated film is easily scratched and transferred to the copper foil. According to the present invention, the arithmetic average roughness (R a) of the surface of the resin coating film does not exceed 0.5 μm (determined in accordance with the regulations of JIS B0601). If there is any irregularity on the surface of the resin coating film, it will be transferred to the copper foil, which hinders the accuracy of the printed circuit board. This paper size applies to China National Standard (CNS) A4 specification (210 X 297 mm) Packing -----.— ^ Order --------- (Please read the precautions on the back first-then fill out this Page) 590885 A7 __B7___ 5. Description of the invention (6) The resin coating film is mainly composed of organic resin. Since the surface-coated steel sheet of the present invention is used as a release aid for hot pressing at high temperatures, the organic resin must have heat resistance and good releasability (determined from the contact angle of the gear oil mentioned above). It includes, for example, epoxy resins, phenolic resins, polyimide resins, polyimide, polyetherketones (ketone resins), unsaturated polyester resins, all aromatic polyesters. Any known cross-linking agent can be added to these resins to increase the hardness of the resin coating film. Cross-linking between polymer chains helps to form a dense film. In addition, release agents such as silicone resins and fluororesins can be added to these resins to improve the releasability of resin-coated films. The release agent reduces the surface energy of the resin coating, thereby improving oil repellency. The amount of release agent should be 0.5-10% by weight of the resin coating. Below this specified amount, the release agent is not effective. Beyond this amount, the release agent will move to the copper foil, making it more receptive to ink when printing circuits. In order to improve the releasability, the resin coating is preferably combined with a surface roughening agent, which gives the resin coating a slight surface irregularity. An overly rough surface (Ra greater than 0.5 micron) is not welcome, but a moderately rough surface helps releasability. Any particulate inorganic substance can be used as a surface roughening agent, such as silicon dioxide, aluminum oxide, and magnesium oxide. The weight of the formed resin coating should be 0 · 5-8 · O g / m2. If the basis weight is less than 0.5 g / m2, resin coating will not be able to completely cover the surface irregularities of the steel sheet, and therefore the coated steel sheet will be transferred to the copper foil. In addition, the coating of the coated steel sheet is too thin, and the releasability and corrosion resistance are not good. Appropriate basis weight of resin coating does not allow internal circuits (in copper foil and pre-paper sizes, the Chinese National Standard (CNS) A4 specification (210 X 297 mm) is applicable) -9

If the basis weight exceeds 8 · 0 g / m2, the resin coating may cause irregularities in the internal circuit to be transferred to it, and thus render the coated steel sheet no longer available for release. According to the present invention, a resin-coated film may be coated on a plated or unplated steel plate using any conventional method (such as dipping, roll coating, spraying) to manufacture a surface-coated steel plate, followed by heating and curing the coating film. Steel plate (plated or unplated) has controlled tension characteristics and surface roughness, which can produce good results in preventing transfer and providing a smooth surface. To prevent the transfer of internal circuit patterns during hot pressing, high tensile strength (greater than 30 ON / mm2, preferably greater than 400 N / mm2) and high hardness steel plates. From the viewpoint of preventing migration, the upper limit of the tensile strength does not exist. However, the practical upper limit is 1700 N / m2, mainly due to the fact that the tensile strength is too high and it is difficult to provide satisfactory flatness during rolling. According to the present invention, it is recommended to use plated or unplated steel sheet with a drop point above 200 N / mm2 to prevent the internal circuit pattern from shifting during hot pressing. In other words, by controlling the tensile strength or / and the drop point, the transfer can be prevented. The fall point is not only related to preventing migration, it can also improve surface smoothness. Therefore, it contributes to the appearance of the surface-coated steel sheet. In addition, the steel plate (used as a release plate) should have appropriate rigidity so that it can uniformly press the laminated substrate during hot pressing. According to the present invention, the yield point of the steel sheet should be higher than the paper size applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) _ _ r ---------- installed -----. --- ^ Order --------- ^ 9 (Please read the notes on the back before filling this page) 590885 A7 ____ Β7 _ V. Description of the invention (8) 2 0 0N / mm2 (3 0 0N / mm2 is preferred), so that it meets the requirements of preventing transfer and appearance. Otherwise, the resulting copper-clad laminate will cause a noticeable irregular surface due to the prepreg. From the viewpoint of preventing migration and appearance, there is no upper limit for the drop point. However, it is preferably lower than 15 00 N / mm2, because the drop point of the steel sheet is too high to roll out the desired flatness. In order to prevent the surface of the release plate from being irregularly transferred to the copper foil during hot pressing, the steel plate should have a smooth surface with a surface roughness (Ra) of less than 0. 30 microns, preferably less than 0.2 microns. The surface roughness of any steel plate exceeds this specification, and its surface irregularities will obviously transfer to the surface of the copper-clad laminate. From the standpoint of preventing migration, there is no lower limit for the surface roughness (Ra); however, Ra is preferably greater than 0.05 micrometers, because the Ra of the steel sheet is too small, which will make its scratches noticeable. The surface-coated steel sheet of the present invention is a very useful release medium when manufacturing copper-clad laminates. It can replace traditional mirror-finished stainless steel plates and release films and can be reused.

By selecting the type of steel and annealing method, the steel plate has appropriate tensile strength and drop point. Through various surface roughness rollers (cold rolling and hardening cold rolling), the release plate has an appropriate surface roughness (Ra). The hardened cold-rolled steel sheet is electro-galvanized (20 g / m2 of zinc) and subsequently treated with chromate (20 g / m2 of chromium).

Description of the invention (18) Chrome-plated steel coating contains 100 parts (by weight) epoxy Resin and 5 parts silicone resin (solid) resin solution. After baking, the resin solution is converted into a resin-coated film with a thickness of 3 microns, and its function is coating for release. The hardness of the resin coating film can be adjusted by changing the amount of mineral resin (which can be crosslinked with epoxy resin) and the baking temperature. Therefore, the obtained release plate was tested according to the following method. Incidentally, the contact angle of all the samples tested in this example is greater than 15 degrees. The test method is the same as in Example 1. 1 · Tensile characteristics According to J I S Z 2 2 4 1 (Metal material tension test method), the specimen N 0 · 5 specified in J I S Z 2 2 0 1 was used to test the tensile strength and drop point of the sample. These specimens do not have a clear drop point, which is considered to be equivalent to the guaranteed stress at 0.2% of the permanent deformation. 2 · Surface roughness (R a) The calculation of the surface roughness is based on the surface structure table ("Surfcom 554A" of Tokyo Seimitsu Corporation) according to J I S 0 6 0 1 to determine the arithmetic surface roughness (R a). 3 · Pencil hardness Measured according to the method provided by J I S K 5 400 (the method is the same as in Example 1). The result is expressed by the hardness of the pencil that caused the coating film to be scratched. 4.

Description of the invention (22) As can be seen from Table 6, samples 5 3 to 6 8 are good in anti-transfer, and the irregularities caused by the prepreg are very Less' looks good. The tensile properties (fall point and tensile strength) and Ra of the steel plates of these samples all meet the requirements of the present invention. In addition, since the pencil hardness of the resin-coated films of these samples is in a proper range, the crack resistance is also improved. Incidentally, the resin-coated film has the ability to be repeatedly released 7 times. [Effects of the Present Invention] The surface-coated steel sheet of the present invention comprises a steel sheet (plated or unplated) and an oil-repellent resin coating formed on the surface. Therefore, it has excellent heat resistance, releasability, surface hardness, and surface smoothness. It can be used as a release board for pressed laminates such as printed circuit boards. Due to its good properties, it can be reused, and does not need to be treated like a traditional mirror-finished stainless steel plate or release-coated aluminum foil, which requires special treatment before use. Therefore, the present invention is beneficial both in terms of cost saving and material saving. In addition, the surface-coated steel sheet of the present invention can be used as an oil-repellent steel sheet in various fields and release plates.
