Effect of Current Stressing on Mixed Solder Joint Resistance and Temperature
This paper aims to investigate the impact of current stress on the electrical performance of mixed solder joints made of SnPb with SnCu and SnPb with SAC305. This information is currently missing and requires further research. The resistance of current-stressed pin-through-hole (PTH) solder joints,...
