Summary: For high-reliability applications in harsh environments, better understanding of the acceleration factors under the stresses of operation is required. Prolonged exposure of copper wires at elevated temperatures can result in excessive intermetallic growth and degradation of the bond interface. Mold compounds used for encapsulation can vary widely in their formulations including ionic content, pH, porosity, and diffusion rates. Selection of the right material combination plays a key role in defining the lifetime of the wirebonded system. This talk will discuss the combined effect of various operational parameters such as temperature and bias, along with material properties, in the development of a model to predict the remaining useful life of Cu-wirebonded packages.
