The requirements for the reliability of electronic systems becomes constantly higher. Therefore, in particular, the strongly growing automotive industry will be influenced, where the number of electronic circuits and the installed power is constantly increasing. Meanwhile for example a hybrid vehicle can be powered by an electrical system with more than 100 kW. The increasing power density of these circuits and the use of the components at higher ambient temperatures lead to the fact that the electronic components will heat up more and more. Additionally the further integration of electronic components requires a higher reliability of single components. With higher complexity it is more and more a challenge to prove the total reliability of these circuits by accelerated tests. A concept how to secure reliability is proposed and discussed. It is based on the mission profile, which describes the stresses applied to the electronics, the virtual qualification, the risk assessment based on the physics of failure and the robustness validation.
