Webstate reaction of Au/In48Sn, Shohji et al.17 found a double layer of AuIn 2 /Sn-rich γ-phase formed on the interface between the Au substrate and the In48Sn solder. The AuIn 2 layer grew toward the In48Sn sol-der, showing that the diffusion rate of Au atoms through the AuIn 2 layer was much greater than that of In atoms.
