The Third International Symposium on 3D Power Electronics Integration and Manufacturing (3D-PEIM-20) will be held on June 22-24, 2020. This symposium will be held at the Osaka University, Suita Campus in Japan. This is the first time to have this symposium outside the USA. It will include worldwide experts representing a wide range of disciplinary perspectives to advance the development of future 3D power electronics systems. Asia is the factory of the world and has a big customer base for advanced power electronics technology. 3D-PEIM is an excellent opportunity to learn about leading edge R&D innovations in 3D power packaging. The focus of the symposium will be on additive, embedded, co-designed, and integrative packaging technologies and the symposium will emphasize the need to address mechanical, materials, reliability, and manufacturability issues in small, smart, power dense components and modules.
