..., the interconnections between the microcomponents and PCB can be made using micro-bump solder (Totta, 2001). The ternary alloy Sn–Ag–Cu (SAC) is currently the most commonly used alloy for the fabrication of solder bumps (Weng, 2017). The miniaturization of microcomponents, combined with high heterogeneity in materials...

... at different soldering temperatures, which indicated that the four kinds of Cu/SACZ/Al joints solder were tightly combined and that there were a few defects between Zn particles. The defects were three sources, oxide inclusion of solder particles, incomplete filling of the molten SAC particles because...
