With increasing power loss of electrical components, the thermal performance of an assembled device becomes one of the most important quality factors in electronic packaging. Due to the rapid advances in semiconductor technology, particularly in the realm of high-power components, the temperature dependence of long-term reliability is a critical parameter and has to be considered with the highest possible care during the design phase.
