IGBT(Insulated Gate Bipolar Transistor), Chinese name is "insulated gate bipolar transistor". At present, the two products mainly used in IGBT module potting are epoxy glue and silicone gel. The mainstream high-power IGBT modules are used in combination with silicone gel and epoxy glue, which provides good electrical insulation protection (silicone gel) and good mechanical strength protection (epoxy glue) for the module.
Silicone gel is a kind of liquid additive silicon gel that can be cured at room temperature and can be cured at high temperature. It has excellent moisture resistance, water resistance, ozone resistance, radiation resistance, climate aging resistance and other characteristics. It can be used for a long time at -40β ~ 200β, with excellent electrical performance and good chemical stability. The water-like transparent silicon gel, also known as jelly glue, is widely used in electronic potting, lighting and medical fields with low ion content, providing the best insulation protection for the chip
