In accordance with the present invention, it has now been found that glycidyl epoxy resins containing substitution on the epoxide ring can be used with conventional epoxy curing agents and fluxing agents to produce underfill adhesives that are suitable for use with silver-based alloys. Owing to the structural similarity of the new materials to conventional epoxy resins, physical and material properties of the invention formulations are altered little, if at all, relative to products currently in use, and so are highly compatible with existing processes.
根据本发明,现已发现含有环氧环上取代基的环氧
树脂可以与传统的环氧固化剂和流动剂一起使用,制造适用于
银基合
金的下填充粘合剂。由于新材料与传统环氧
树脂的结构相似,因此与目前使用的产品相比,本发明配方的物理和材料性质几乎没有改变,因此与现有工艺高度兼容。
