摘要

Within this paper, we present a guideline for the mechanical acceleration of reliability experiments for end-of-lifetime prognostics of metal based die attach materials. First, we used an advanced hybrid nano-effect sintered silver layer as interface between die and substrate which has very good electrical and thermal conductivities. Two pairs ofexperiment/simulation are scheduled. An isothermal mechanical 3-pt bending experiment to induce fatigue the specimens rapidly as well as a thermal induced strain fatigue by thermal chamber for validation. The manufactured specimens are designed to be used for both. With a FEM of this subsystem to simulate the failure parameter which is the accumulated von Mises strain, lifetime modelling can be performed.
