Abstract
The dissimilar welding of titanium and copper by fusion welding is very difficult because the melting points of the materials are very highly different and strong brittle intermetallic compounds (IMCs) can be easily produced in welded zone and heat-affected zone, etc. Friction stir welding was employed as a type of.....

Abstract
This study examined the effects of the Sn content in a pure active metal filler Ag-Cu-Ti for the brazing of a Cu/ Al₂O₃ joint. The optimal content of Sn to effectively wet alumina was 5 wt%. The microstructure of the brazed joint showed the presence of an Ag-rich matrix and..... More

Abstract
The reliability of printed circuit boards (PCB) has emerged as a critical concern as the size of solder bump decreases and current density to solder bump increases by fine pitch formation. The main failure mode of solder bumps is open-circuits due to void formation as intermetallic compounds (IMC) grow, mainly..... More
