This paper presents mining the worst thermal fatigue life of solder joints on chip components used in vehicle electronics. The authors proposed an isothermal fatigue test method using real size solder joints to get the fatigue properties. The Manson-Coffin's law given by this method could improve the agreement between the simulation model and experimental results. Based upon the Manson-Coffin's law...
This paper presents mining the worst case of thermal fatigue life of solder joints on chip components used in vehicle electronics. Typical 36 cases with various solder shapes were examined. Thermal fatigue life including not only the crack initiation but also crack propagation was evaluated by using the finite element method. Based upon the case study's results, it was found that when a crack propagates...
