Power electronic substrate

From Wikipedia, the free encyclopedia

The role of the substrate in power electronics is to provide the interconnections to form an electric circuit (like a printed circuit board), and to cool the components. Compared to materials and techniques used in lower power microelectronics, these substrates must carry higher currents and provide a higher voltage isolation (up to several thousand volts). They also must operate over a wide temperature range (up to 150 or 200 °C).

Active metal brazed substrate

Another technology to attach thick metal layers to ceramic plates is the AMB (active metal braze) technology. With this process a metal foil is soldered to the ceramic using als[clarification needed] solder paste and high temperature (800 °C – 1000 °C). The process itself requires vacuum. Therefore, though AMB is electrically very similar to DBC, it is only suited for small production lots.
