This project successfully developed a CEM-3 copper-clad sheet with high thermal conductivity and heat resistance and good processing performance through the efficient compounding of epoxy resin and thermally conductive filler. The product is prepared by adding a large amount of micron-level thermally conductive filler to the epoxy resin, using the high thermal conductivity epoxy resin as the base, compounding with thermally conductive inorganic particles to prepare the glue, and pressing and molding by adjusting the pressing method.

The curing agent in the composite resin layer is bisphenol A phenolic resin, which improves the cross-linking density during curing and can make the produced board have excellent heat resistance at the same time, further improving the board Tg value. After hot pressing, the CEM-3 sheet has high thermal conductivity, with a thermal conductivity of 1.0W/M.K or more, which can be a good solution to the rapid heat dissipation of electronic components such as LED lighting; at the same time, it has excellent heat resistance.
