Due to the globally increasing demand for energy, a greater use of renewable energies is required to reduce carbon dioxide emissions. Efficient power semiconductors are needed for energy conversion, which is why the markets for IGBTs and modules are growing by around 15% annually. The most competitive IGBTs are based on 300mm silicon wafers: >1700 volts, higher power density, reliability, and energy efficiency for mobility, industry, and grids, as well as the latest findings in Industry 4.0, are brought together in Power2Power.

This will strengthen and expand the competitiveness of Germany, specifically along the entire value chain of power electronics.

At the University of Rostock, new testing methods are being developed for the pilot lines, which are oriented towards later applications while simultaneously reducing testing efforts. The goal is to replace the optical inspection of solder joints with electrical tests, enabling faster and more accurate testing. The test specimen will be heated through switching losses to allow for a quick test at operating temperature. The measurement of temperature-sensitive parameters could help assess the solder joint quality.
