Abstract

The study of thermomigration on Sn-Ag-Cu solder sphere subjected to a high thermal gradient of 1100°C/cm is presented. After 286 hours, the hot end showed a thin and flat intermetallic compound (IMC) while the cold side showed a scallop-like Cu6Sn5 IMC. Small voids can be seen within the Cu6Sn5 IMC after 712 hours on the cold side, while the IMC on the opposite side showed no observable changes.
