Abstract

The effects of the reduction of the Ag content and the addition of In on the mechanical properties, soldering characteristics and reaction behavior at solder/package interfaces are investigated in this study. It was found that the addition of In significantly improved the wettability of the solder at reflow temperatures ranging from 230 °C to 240 °C. Moreover, the addition also improves the elongation of the solder alloy, thereby increasing the toughness of the alloy. With the optimization of the In and Ag contents, a Sn-Ag-Cu-In quaternary alloy would be a strong candidate to replace the Sn-3.0Ag-0.5Cu composition.
