description The invention provides a ceramic PCB manufacturing process based on graphene material. The process comprises the steps of coating one surface of a copper belt substrate with a layer of photoreceptivewet film; according to a preset circuit diagram, using diagram film for conducting exposure and development on the copper belt substrate coated with the photoreceptive wet film; placing the copper belt substrate with the wet film diagram in electroplate liquid for electroplating; removing the photoreceptive wet film in the copper belt substrate, with a preset thickness, of a metal wireline layer;forming a layer of graphene film on the other surface of the copper belt substrate with the preset circuit diagram; fitting the pre-obtained green body on the surface of the preset circuit diagram ofthe copper belt substrate; firing the copper belt substrate with the preset circuit diagram, which the green body fits, with a preset temperature lower than the metal wireline melting point to be integrated, a metal wireline wi
