Research Abstract

In this research, the idea based on lowering the amount of oxidized layer and stabilizing the surface of solder particle was introduced into the development of new type of halogen-free solder paste. Oxide layer of solder particles were removed and little amount of halogen (5 times lower than 900ppm)were remained on the surface of solder particles. Solder paste, synthesized by treated powder and non-halogen surfactant, showed excellent performance for integration, regardless halogen content was 70-180ppm. Reaction mechanism was also investigated and it was applied to establish for another metallic nano particles paste.
