面層にく−ズリングが発生することが多かった。<Conventional technology> Conventionally, such composite laminates using multiple base materials use glass cloth for the surface layer and heat-resistant epoxy resin, but when parts are mounted, In processes that locally apply heat, such as with a soldering iron, slinging often occurs on the surface layer.

中心のガラス不織布層との間で加熱による熱膨張の差が

れているが、未だ十分な解決法は見出されない。The cause of this is not fully clear, but it is thought that the difference in thermal expansion due to heating between the surface glass cloth layer and the central glass nonwoven fabric layer is large, causing the resin bond to be locally broken. No satisfactory solution has been found.

ある。Means for Solving the Problems> The present invention provides an epoxy resin copper-clad laminate that uses a glass cloth for the surface layer and a glass nonwoven fabric for the center layer as the base material, and uses opened glass as the glass cloth for the surface layer. 1) A method for manufacturing a laminate, characterized in that a cloth is used.

用プリプレグを得る。In the present invention, the opened glass cloth is a normal glass cloth that has been loosened to reduce the gap between the yarns that make up the cloth, and usually has an air permeability of 7 cc.
/ct/sec or less. The opening method may be either mechanical or chemical, but it is particularly preferable to mechanically open the fibers after surface treatment of the glass fibers. This is impregnated with an epoxy resin to obtain a surface layer prepreg.

アルミナやシリカなどの充填材を含有するエポキシ樹脂
を含浸して得られる。The prepreg for the center layer is obtained by impregnating a glass nonwoven fabric with an epoxy resin or an epoxy resin containing a filler such as alumina or silica.

ポキシ樹脂銅張積層板を得る。An epoxy resin copper-clad laminate is obtained by overlapping a plurality of these prepregs for the center layer and one prepreg for the surface layer on both sides, and then overlaying copper foil on one or both sides and molding under heat and pressure. .

ミーズリングの発生を抑えることができる。Since the copper-clad laminate thus obtained uses opened glass cloth for the prepreg for the surface layer, even when heated, especially localized heating with a soldering iron, etc., the opened glass cloth cannot be heated. The stress caused by thermal expansion is alleviated by the fibers, and the difference in thermal expansion with the center layer is reduced, thereby suppressing the occurrence of measling.
