White Paper on Challenges & Market Needs in Powerelectronics
In his first white paper entitled Power Electronics Market Needs & Manufacturing Challenges , Hans Ulrich Voeller, Senior Product Manager Substrates, sheds light on the growing requirements for ceramic substrates for high-performance power electronics modules in the context of global trends such as electrification and decarbonisation.
With the market forecast to grow to over USD 70 billion by 2033, the white paper shows how crucial the right choice of materials is for the reliability and performance of modern electronics solutions. Traditional materials such as alumina (Al₂O₃) are increasingly reaching their limits as power density increases. Ceramics such as aluminum nitride (AlN), zirconia toughened alumina (ZTA) and, in particular, silicon nitride (Si₃N₄), on the other hand, offer significantly better thermal and mechanical properties.
A central theme of the white paper is the importance of the highest quality requirements: Even microscopically small defects in substrates can lead to failures - which is why CeramTec relies on the strictest testing processes. These include highly automated 2D/3D inspections, high-voltage testing and AI-supported defect detection. These technologies enable CeramTec to guarantee consistently high quality even for large quantities.
In conclusion, Hans Ulrich Voeller emphasises the need for continuous innovation: "The increasing miniaturisation and power density of modern power modules require permanent further development of both materials and production technologies.
