摘要: 合适的粘接促进剂有助于提高环氧模塑料(EMC)与金属基材的粘接性能,进而改善EMC与金属基材的分层问题,提高封装的可靠性。主要讨论了3类粘接促进剂的作用机理,通过试样的抗拉测试、抗剪测试、超声波扫描分层测试,分别验证了环氧基硅烷偶联剂、氨基硅烷偶联剂、钛酸酯偶联剂、氨基咪唑4种粘接促进剂对EMC的粘结力和分层的影响。这4种粘接促进剂都能在不同程度上提高EMC对裸Cu和镀Ag引线框架的粘结力,氨基咪唑改善EMC对镀Ni引线框架的粘结力和分层的效果最好。

Abstract: Proper adhesion promoter effectively increases the adhesion performance of epoxy mold compound and improves the delamination of epoxy mold compound on metal substrate and reliability. In the paper, the mechanisms of three kinds of adhesion promoters are discussed. Adhesion is tested by Pull and Shear tests, and delamination is tested by Ultrasonic Scanning test. Effects of four adhesion promoters, of the three kinds mentioned above, on adhesion and delamination performance of epoxy mold compound are researched. The four adhesion promoters all increases adhesion of epoxy mold compound on Cu and Ag. Amino imidazole is the best to improve the adhesion and delamination on Ni.

Key words: adhesion promoter, epoxy mold compound(EMC), adhesion, delamination
