Abstract

PURPOSE:To enable to obtain superior workability and reliability with regard to connection of electronic parts by a simply connecting operation by a method wherein an anisotropically conductively adhesive film containing a proper quantity of metal particles having the average particle diameter of the specified range is used for a thin insulating adhesive. CONSTITUTION:The surfaces of the electrodes 2 of an IC chip 1 and lead terminals 4 on a substrate are connected interposing an anisotropically conductively adhesive film 3 between the surfaces of the electrodes 2 and the terminals 4. At the connecting method thereof, an anisotropically conductively adhesive film containing 0.1-10vol% of metal particles having the average particle diameter of 0.01-10mum in an insulating adhesive of thickness of 50mum or less is used for the film 3. When the average particle diameter of the metal particle is 0.01mum or less, an insulating property in the facial direction can not be obtained, while when it is 10mum or more, probability that the particles exist between adjoining circuits becomes large when the circuits are microminiaturized. Moreover, when content of the conductive particles is 0.1vol% or less, conductivity in the thickness direction is hard to be obtained at connection of the fine circuits, while when it is 10vol% or more, an insulating property between the adjoining circuits can not be obtained.

Description

[Detailed description of the invention] [Keibu town where inventions are made] The non-invention is a V-circle in the connection blade between electronic accessories such as a circuit board and circuit board threads. [Technical background of the invention] As electronic components become smaller and thinner, Sakaki materials, which can be used to create circuits, are being developed by stock dealers.

This IL etc. is 0.0 as electronic parts. Ushijinpay nesting circuit.

Taniguchi's main display type, switch tilt is 69, and Kuchiji's is progressing with the implementation of printed distribution imitations, 柾显设计窶田かちり, and secret role.

T! The setting of the IIu circuit (hereinafter abbreviated as IC) will be explained.

Conventionally, we have used wire bonding and 7-eighth wire bonding for connections between IC and & similar circuit threads, M#S connection to via lid integrated IgIII6, and connection methods for passive system external elements. It is roughly divided into three types: wire bonding, which is performed by force, and is a method of connecting the electronic parts and circuits one by one to Lv-dependent connections such as A U R A Z. However, due to the trap of one of the shrines being cut and losing the function of the parts, Yori is interested in 2-eighth bonding in order to improve his wisdom and deal with MJ@Dogitetsu. 07 Engineering Iss Bonding A''Electronic Materials G) Although I tried to connect the M pole with the circular wire and the T shell in the cloth N, compared to the wire bonding, the wire bonding was better than the wire bonding. It is also attracting attention because bonding or leveraging is done by the operation of 11gI without relying on electric ridges. As a connecting force method in this two-way supporting, the analogy is that of 11- for one cage and the other. Bump method of placing Cu layer and melting solder layer,

& increase 1/CI C or #I filamentous temperature of 200℃ or more, and it becomes a fibrous image.
In addition, since the parts corresponding to the phosphorus decorations are subjected to a sprinkling process, it is possible to perform the sprinkling with blood, but it is not possible to do so with electricity and mechanical pressure. There is a lack of daughter-in-law tax in 1990'E7 (there has been no attempt to connect with the electric carpenter), but electronic parts, especially those of the 4-year-old man, have decreased in value due to the elaboration of the VPi. !Apply a tortoise-conducting layer agent only to the 2nd circuit section and apply it.
There are now 0 countries in which to listen.

As a countermeasure for the above, we made use of the elasticity and thickness of the seven-brass fabric and the elasticity of the rubber. 55-55260, Ikai-56-55971) (Because lj!lI Bo 10 attack is required to attach ψ, it causes variation in 4# electric property, and 1d Peng The ability to connect using the shielding agent of the O 1 look input

No. 773) Although it is true that there is no uniform thickness of the preservative that shows different properties, it is a great effort to increase the variation in the thickness of the preservative. The desecration of the land caused by the Sung Dynasty, the trap that made you have to invest in the classification of layers, the fact that Yuso T4 was given to IC, and the average tenacity of the materials given to the earth depended heavily on the religion. The thickness of the rowing pigeon is the same as the thickness of the rowing pigeon.
1wI ICQ with progressing thinning) We will be looking at entry points such as the lack of Bunpai Ryu due to Ikui, and the lack of influence of Choshogin due to the use of particles.

He was treated as an enemy by the enemy.

4- Apply the material by vigorous stirring, spread it on top of the separator, etc., and lay it on the dry bed. Arranged in the 1 direction, @reducing force 1 hs or a 艺 (As a known method, the conductive material that gives magnetic properties is formed by molding the composition proboscis under the molding method) By arranging the conductive material in the thickness direction, it is possible to create a contact sheet with anisotropically arranged conductivity imparting material.Basically, it is possible to create a contact sheet r with conductivity imparting material or anisotropically arranged particles in the thickness direction of the film. Therefore, the manufacturing method does not matter, and the thickness of the shielding sheet, a, must be at least two times larger than the average plate diameter of the conductivity-imparting material particles, and C, which is less than 50 μm, is required. If it is less than 2 degrees, 4ft, fjtδn will not be enough for Senryuzai or Ishiyuki, and it will be easy to cause the knitting particles to change.

If the overall film thickness is 50 μm or more, the electrical resistance level will be reduced to 1, and the thickness of the connection part will be affected when wearing. If you handle it with a sheet, it will be better to protect it from dust etc.

Next, according to the above, we will continue to explain the 7C pile force method using the samurai n trap force # electrically compressed film. 〇 Connections are made on the surface of the electronic component and the board circuit thread.
This can be done by interposing a specific force-conducting film and applying heat, pressure, or silent pressure to the edge of the blade.

It is preferable to cross-link the σ1 shielding agent in order to strengthen the interface between the nyc connection and the interface between the nyc and the nyc connections. Reactions and addition reactions react to the proportions of the polymers.

In rare cases of reaction, it is good to use amines, isocyanates, melamine, etc. in combination.

The above-mentioned protection has been performed for the lifting platform of 2-eighth bonding between the IC and the board circuit thread, but inexplicably, Yamakawa Dero v1 open *a (face bonding) was also applied to the connection between the circuit direction and the circuit surface. For K row 9, I put it in the opposite direction and used it for general purposes, so I made it electrically shielded with a small fence on bamboo! Since the decomposition is still present on the lifting platform of the 21st station, it is suitable for the south.

For this purpose, two printed circuit boards made of Karasu epoxy base material of Dohaku U width 50 μm and Vituna 100 μm were heated at 1150°C.
