Abstract :
Summary form only given. The relationship between microstructure and fatigue resistance of solder interfaces was studied by examining micromechanisms and micromechanics of fatigue crack growth along a series of model interfaces. While the fatigue crack was seen to prefer staying in the solder when propagating at high rates, interfacial crack sliding was predominant in the near-threshold regime. A micromechanical model of interfacial crack sliding was developed, based on the interface fracture mechanics concept
