AlSiC was first used in the US radar chip substrate to replace tungsten copper. After the replacement, the heat dissipation effect is excellent, and the overall weight loss of the radar is 10 kg, which makes the aluminum-silicon carbide material attract attention.
High-current IGBT (Insulated Gate Bipolar Transistor) modules generate a large amount of heat during operation. The AlSiC material is usually used to fabricate the IGBT substrate, and the high-power IGBT module is firmly packaged, so that the chip can be used in vibration, high temperature and dust. The Aluminum Silicon Carbide IGBT Base Plate is very light, only has a 1/3 weight of the copper, but its bending strength is as good as the steel. This makes it excellent in seismic performance, exceeding the copper substrate.
Therefore, in high-power electronic packaging, Aluminum Silicon Carbide IGBT Base Plates are irreplaceable materials due to their unique combination of high thermal conductivity, low thermal expansion coefficient, and flexural strength.
