An important part of the SAE J1211 Robustness Validation Handbook is headed “Analysis, Modelling and Simulation”. It is based on the Physics-of-Failure approach which means that appropriate models are a prerequisite for lifetime simulation. In addition the different stresses which are applied during operation have to be considered (“mission profile”).

The workshop will present and discuss the state-of-the-art of lifetime prognostics in the field of power electronics. Some of the questions which should be answered are:

• How can the mission profile be handled?
• How to deal with multi stresses?
• Root cause for failures in the field or after accelerated testing
• What is the best suited model for a given failure mechanism?
• Which parameters are needed for calibrating models and how can they be extracted from experiments?
• What tests are best suited for verification of lifetime results?

The workshop is divided into six sessions which are: active and passive devices, interconnects (bond wires and die attach), power modules, systems on PCBs and environmental stresses.

The workshop is chaired by Prof. Eckhard Wolfgang (ECPE), Prof. Thomas Licht, University of Applied Science Dusseldorf, Dr. Olaf Wittler (Fraunhofer IZM) and Thomas Harder (ECPE).

All presentations and discussions will be in English.
