Fabrication of a PCB-embedded Half-bridge Module
Embedding power semiconductor devices into printed circuit boards (PCB) has been investigated for several years. With this technology the PCB is built-up around a bare semiconductor chip. Compared to the conventional approach, where packaged semiconductors are soldered to a PCB, which serves as circuit carrier only, embedding of power semi-conductors (such as MOSFET or IGBT) offers many benefits.
This technology is available from a few specialized PCB manufacturers, who offer production only for high volume applications. In this application report, which is available free of charge from the LPKF Knowledge Center, you can read how a demonstrator board with an embedded MOSFET half bridge is developed, fabricated, and tested.
