Abstract :
An energy-based damage criterion, which has not been used previously in solder fatigue-life assessment, was found to be superior to a plastic strain criterion in predicting the fatigue life of different solders. Solder specimens of different size and geometry were tested under different types of control and with different loading modes and aging conditions. The energy-based damage concept was used to interpret aging effects in 63Sn-37Pb solder
