In this application is disclosed an adhesive film for a multilayer printed wiring board which comprises at least the following Layer A and Layer B in the adjacent position, wherein the thermosetting resin composition constituting the Layer B is a thermosetting resin composition which contains a resin having a lower softening point than the lamination temperature concerned in an amount of not smaller than 10% by weight, and can fill with itself (or resin-fill) the through holes and/or via holes concurrently with being laminated onto a circuit board;
Layer A: A heat-resistant resin layer comprising at least one heat-resistant resin selected from the group consisting of a polyimide, a liquid crystal polymer, an aramid resin and a polyphenylene sulfide and having a thickness of 2 to 30 µm,
Layer B: A thermosetting resin composition layer which contains an epoxy resin having at least two epoxy groups in one molecule (Component (a)) and an epoxy curing agent (Component (b)) and is solid at ordinary temperature, with the use of which adhesive film can allows an easy introduction of an insulating layer having excellent mechanical strength at the time of producing a multilayer printed wiring board by a build-up technique, and a multilayer printed wiring board having excellent mechanical strength can, in turn, be provided.
本申请公开了一种用于多层印刷线路板的粘合膜,它至少包括以下层 A 和相邻位置的层 B,其中构成层 B 的热固性树脂组合物是一种热固性树脂组合物,它含有一种软化点低于相关层压温度的树脂,其含量不小于 10%(按重量计),并且在层压到线路板上的同时可以用自身填充(或树脂填充)通孔和/或通孔;
层 A:耐热树脂层,包括至少一种耐热树脂,选自聚酰亚胺、液晶聚合物、芳纶树脂和聚苯硫醚,厚度为 2 至 30 微米、
层 B:热固性树脂成分层,它包含在一个分子中至少有两个环氧基团的环氧树脂(成分 (a))和环氧固化剂(成分 (b)),在常温下为固态,使用这种粘合膜可以在通过堆积技术生产多层印刷电路板时轻松引入具有优异机械强度的绝缘层,进而提供具有优异机械强度的多层印刷电路板。
