|Abstract:||Comprehensive drop tests, failure analyses, and simulations were performed on TFBGA and VFBGA packages at board level. The solder joint failure was induced by the combined stress of mechanical shock and PCB bending. The critical solder ball was observed to occur at the outermost corner solder joint, and fails along the solder and PCB and pad interface under peeling mode. This failure mechanism and location of critical solder joint were supported by same observations in both drop test and simulation.|
