Abstract: Epoxy resins (EP) are the first choice for power module encapsulation materials due to their excellent electrical insulation, mechanical strength and high temperature resistance. As the integration degree of power modules increases and the service environment becomes more demanding, the performance requirements for EP continue to improve. This paper summarises three aspects of EP classification, modification and its application in power module encapsulation, and points out the challenges faced by EP as well as the future development direction. The modified epoxy resin can improve the thermal management capability, insulation performance, corrosion resistance and warping resistance of the power module package. Future research directions include the development of high temperature resistant packaging materials, the exploration of environmental protection and multi-functional epoxy resins, and the combination of new materials and new processes.

Key words: epoxy resin, power module package, modification technique,  thermal management capability, insulation performance
