Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nine-layer track board suitable for use in an actual vehicle.

Conventionally, as substrates for mounting electronic components, laminates have been used, which are made by soaking paper or glass cloth substrates in lif oil and laminating them. As the size of the mackerel used for the use of mackerel became smaller and the speed of calculation became faster, the print layout #1Iik& (hereinafter referred to as j&
7111 of electronic components such as LSI to (abbreviated as “board”)! f: Implementation is strongly desired. Examples of high-density mounting methods on LSI boards include directly attaching the LSI chip to the A board, mounting the LSI chip on a chip carrier such as ceramic, and connecting this chip carrier to the A board in a leadless manner. However, when using the conventional base Ik, the thermal expansion coefficients of silicon or selachic and jkli are greatly different, so when subjected to cooling and heating cycles, the substrate and the 0IIIa part are damaged, which is a drawback. I) I don't know the kick board.

Using this will solve the above drawbacks, but it will not work
& boards have disadvantages such as the S calculator is large and the large substrate is not durable or fast. Therefore, in order to overcome these disadvantages, aromatic polyamide woven fabric is used as the base material of the laminate. It has been reported that ft (IEEE Transactions

1979).

In this method, it is difficult to make the thermal expansion coefficients of the substrate and the TEG carrier the same value, and the problem is that the reliability of the connection part is at stake. Due to the poor conformability, there is a drawback that when using a laminate, the contact force is high, and the layer peeling occurs during the process.

Furthermore, since the aromatic boriyaid fiber has a large thermal expansion coefficient #i in the thickness direction, there is a drawback that the connection reliability of through-hole plating formed on the laminate is low. Furthermore, aromatic polyand fibers also have the disadvantage of being more expensive than conventional fill materials such as paper and glass fibers.

Therefore, as one method to resolve these υ defects, the first
117 shown in the figure! When we created a laminate with steel foil and an outer layer reinforced with resin and aromatic polyamide fibers on both sides of an inner layer reinforced with glass fiber cloth, we found improvements in terms of thermal expansion coefficient in the direction of extension and price. However, the bondability with the copper foil and the quality and authenticity of the base material were still insufficient.The present invention was made to improve the above-mentioned drawbacks.

It is possible to improve the welding properties of I4 foils and textile substrates.

Figures 2 and 5 are cross-sectional views of the laminate of the present invention, and Figure 2 shows glass woven fabric reinforcing inner layer 5 and electrophilic fiber reinforcing outer layer 4 made of glass*M, aromatic polyamide fiber, and F on both sides. In addition, since the gold layer 1 is further provided, the outer layer 5 is made of an electrophilic reinforcing layer 5 with many electrophilic ruts and a mixed woven fabric with a small electrophilic distribution of glass fibers. 21Ia strong layer 402 Formed from a layer of citrus. Regarding the adhesion of the fabric base material, as shown in Figure 3, the mixing ratio of aromatic polyand fiber and glass fiber is changed to 1% to use a woven fabric with a ratio k16<
To prevent MV of one layer from peeling by gradually alleviating the stress between the layers of glass fiber and aromatic holamide fabric, which is a cause of the decline in the layer strength of the horizontal ridges shown in Figure 1.

If the aromatic polyamide fiber is less than 30% (if the glass #It- is more than 70%), the curve of the thermal expansion coefficient in the pronation direction of the laminate is sufficient. Satisfied!
