Aim: Before an electronic/mechatronic product is released for the market it is an important task for the company to evaluate the reliability of the product. The aim of this course is to enable the participants to:
· Work with evaluation of product reliability in a development, production, or test- & reliability department of an electronics company.
· Evaluate, both under accelerating and standard operation conditions, the physical mechanisms most influential on the failure development in components and systems.
· Plan and execute lifetests, wear-out tests and robustness tests and analyse the results.
· Predict an expected lifetime with respect to a single failure mechanism and to guage the prediction accuracy.
· Participate in a development team and supply knowledge on the development of dependable and robust designs
