The high cycle vibration fatigue life characteristics of Pb-free and Pb packages were studied under various mixed mode stress by a new test method and FEM. It was found that the effect of frequency on a high cycles vibration fatigue life of Pb-free and Pb package can be ignored within a range of 10∼25Hz. Using a normal shear stress, the evaluation of Pb-free and Pb package fatigue life was possible without considering a mixed mode stress. The vibration fatigue induced a crack in a solder ball itself.
