| Abstract: | Thermo-mechanical fatigue failure of the packaging materials is one of the main causes for the microelectronic component failure. Tension and fatigue tests on a widely used packaging epoxy molding compound (EMC) were performed under room and high temperatures. A fatigue life prediction model based on fatigue modulus concept was applied and the related material parameters were obtained by the experiments. The temperature effect on the fatigue life of the EMC are considered. This provides the fatigue life prediction of the microelectronic packaging polymer. |
