▎ 摘　　要

NOVELTY - A graphene conducting one hot circuit substrate, the circuit substrate is provided with three hot layer is graphene, the hot insulating layer, conductive layer, the graphene material is graphene body, graphite adherend is graphite sheet or graphite polymer, the hot insulating layer is graphite alkene boron nitride nano-sheet of epoxy substrate-conducting hot glue film, conductive layer is copper or gold foil, silver foil, a conductive layer can be made and a welding circuit of electronic module electrically connecting the graphene with high thermal conductivity and good machinery property of graphene layer conducting hot insulating layer and the electronic component working time of hot can quickly produce conductive out and radiated does not need increase hot substrate volume can obviously reduce the electronic component or working temperature of electronic product.
