Power electronic substrate

（重定向自Insulated Metal Substrate）

Structure of a direct bonded copper substrate (top) and an insulated metal substrate (bottom).

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).
