▎ 摘　　要

NOVELTY - The circuit board has a base plate (1) and electric conduction circuit (2). The electric conduction circuit is used to form machine print by 3D printer through the electric conduction graphite slurry. USE - Three-dimensional (3D) graphene print circuit board for use with high power LED circuit board, flat display and solar panel. ADVANTAGE - The print circuit board has low cost and controllable thickness. The flexible manufacturing of circuit board is realized with wide application prospect. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the three-dimensional graphene print circuit board. Base plate (1) Electric conduction circuit (2)
