Abstract :
To give a proper and accurate estimation of the fatigue life of solder joints, a mechanical fatigue test under mixed-mode loading cases is proposed. The loading phase is controlled by the angle of loading direction. Experiments are conducted with eutectic 63SnPb solder joints. The isothermal mechanical fatigue tests were performed under conditions of several loading phases. Constant displacement controlled tests are performed using a micro-mechanical test apparatus. Failure patterns of the fatigue tests are observed and discussed
