Title: Copper-clad laminate and prepreg
Inventor: KOBAYASHI HIROYUKI
IPC: B32B15/20
Filed: 1994-12-26
Abstract: PURPOSE: To reduce a coefficient of linear expansion in one direction only of a printed wiring board without deteriorating electrical and other various properties by using glass fiber cloths wherein a ratio (warp/weft) of the density of warps to wefts of the glass fiber cloths is within a specific range. CONSTITUTION: A weaving method of a glass fiber cloth may be the same as that for producing an ordinary woven fabric, and examples thereof include Turkish satin weave. Also, a ratio of the density of warps to wefts is at least 1.5 and at most 2.5. In the case where the ratio is 1.5 or below, the effect of reducing a coefficient of linear thermal expansion in a lengthwise direction is insufficient, and, in the case of 2.5 or more, the effect of improving a coefficient of linear thermal expansion does not become more remarkable than that. Therefore, when the glass fiber cloths are formed into a laminate, warpage and the like of the laminate are apt to be caused. It is preferable for a low coefficient of linear thermal expansion that the density of the warps and wefts is at least 45 threads/25mm for the warps and at least 28 threads/25mm for the wefts.  Further, a ratio of the preferable density is at least 1.7 and at most 2.2, and the density (threads/25mm) of the warps/wefts is, for example, 74/36, 52/30, 57/30, etc.
