Abstract :
A mechanical deflection system (MDS) was developed for highly accelerated tests to evaluate the solder joint fatigue performance in printed circuit board assemblies. The MDS test system can be used for design verification and qualification tests for solder joint reliability. Cyclic twisting deformation is imposed on an assembled printed circuit board (PCB) at isothermal conditions. The MDS test technique makes a significant contribution to reducing solder joint reliability testing cycle time. Fatigue performance of the PBGA solder joints subjected to the MDS test was investigated by three-dimensional finite element modeling. The solder joint fatigue lives were computed for several different MDS test conditions
