説明

The growth kinetics of intermetallic compounds formed on the boundary between Au and In-Sn alloy solders were investigated with Au/Sn-27In and Au/Sn-20In diffusion couples. On annealing under the melting point of each solder, the Au-In intermetallic compound layers, such as AuIn2, Au7In3 and AuIn, were firstly formed on the boundary. More continuous annealing caused the formation of Au-Sn intermetallic compound layers on the boundary and the Au7In3 and AuIn layers were disappeared at the same time. On the other hand, it was found the Au-Sn compound layers were already formed on the boundary by annealing for 60s at 523K, which temperature is over the melting point of both solders.
