To enhance the ability of lead-free solder joint to resistfailures induced by mechanical impact and shock, someresearchers have introduced low-Ag lead-free solder. In thisstudy, the formation and evolution of IMC, the fracturemorphology and performance of solder joint between SAC ...
In this study, the brittle fracture of intermetallic compound (IMC) between low-Ag SnAgCu (SAC) solder and under bump metallization (UBM) under high-speed pull condition is studied for wafer-level chip-scale packages (WLCSP). The fracture morphology and fracture mechanism of IMC ...
