Abstract: The paper reports a failure analysis technology for solder joint defects in SiP modules. The experiments results of 3D X-ray and metallographic analysis are compared, which verified the method of 3D X-ray analysis. The detailed mechanism and mode of the solder joint failure are explained, and suggestions are given for improving the performance of solder joint.

Key words: system in package(SiP), failure analysis, solder joints, defects, X-ray, metallographic analysis
