More and more functions in a car are now carried out or supported by electronics. As safety related functions are concerned, the requirements of reliability of electronic modules nowadays are even higher than before. On the other hand the demand to place electronic modules into a harsh environment is increasing. Reliability tests become more expensive and time consuming. In order to shorten the development process there is a need to optimize the reliability of a given design by simulation. The design for reliability approach uses simulation to predict the lifetime of a design in a given environment. This method has been applied to automotive problems. Integration of mechanical and electrical components in one module has many advantages offering reduced cost, increased EMC, reduced volume, less weight and increased reliability. The design for reliability concept was utilized to optimize the design of a mechatronically integrated power electronics in an engine cooling fan. New electronic packages that have been successfully applied in the telecommunication industry or in the computer industry are qualified for the use in the automotive environment.
