摘要

Electronic failures can result in immediate system shutdown with no advanced fault or warning signal. As a device is operated thermal and/or mechanical loads are induced across the package. These loads are translated from the global package level to the localized interconnect level. VEXTEC's patent pending material-based simulation software accounts for real world interconnect variability and predicts probably of failure as a function of device operating time. This NAVAIR sponsored SBIR project demonstrated feasibility for using conventional, off-the-shelf sensing, to predict solder degradation due to thermal cycling as a means to prognosticate electronic device reliability.
