Microstructural Evolution During Electromigration in Eutectic Tin-Bismuth BTC Solder Joints
The subject of this follow-up paper is the microstructural evolution of BTC eutectic Sn-Bi solder joints during electromigration. The growth of intermetallic phases at the solder-substrate interfaces and the extent of bismuth electromigration were measured as a function of temperature, current density and time in a bid.
