(CN209030462-U) NOVELTY - The utility model claims a graphite-metal composite material is a PCB of the conductive circuit and a motor. wherein the PCB comprises one layer or multi-layer base plate and the base plate surface of the bottom conductive wire layer, the bottom conductive wire with graphene-metal composite material layer. primary conductor of the conductive circuit of the graphene-metal composite material layer-as the PCB, compared with pure copper material, graphene conductivity of-metal composite material is higher than pure copper material, and the density of graphene-metal composite material is low, so the PCB provided by the utility model while maintaining the electric power condition of the circuit can be reduced and the total weight, overcomes the short PCB further lighter. PCB claimed by the utility model while maintaining the lower conductive line thickness can bear higher circuit electric power and expanding PCB application market. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of printed circuit board containing graphene-metal composite material motor, which involves using substrate plate, graphene oxide and ionic liquid containing metal ions; and (2) motor, which comprises motor stator comprising printed circuit board containing graphene-metal composite material.
