AVT & surface analysisPower Modules

In the production of high-quality power modules, yield is a key cost factor. The increasingly complex manufacturing chains of such modules involve numerous material interfaces whose boundary surfaces are exposed to significant thermomechanical stresses during production and in subsequent field use. These surface interfaces are often difficult to specify within the supply chain and are naturally subject to certain tolerances. Such tolerances can lead to reduced yield, resulting in cost or quality disadvantages.
