▎ 摘　　要

NOVELTY - Device comprises an insulating material barrel (1), where the top opening end surface of the insulating material barrel is fixedly provided with a transverse supporting one (2). The transverse supporting two is supported and fixedly installed with a longitudinal supporting one (4), longitudinal supporting two (5), the bottom wall of the longitudinal supporting one is provided with a graphite plate through a pair of hanging rod one (6). The graphite plate is connected with a negative lead (8). The bottom wall of the longitudinal supporting two is provided with a fixing plate through a pair of hanging rod II. The side plate surface of the fixing plate opposite to the graphite plate is fixedly installed with a circuit board. The insulating material barrel is injected with a graphene electroplate liquid (13). USE - Device used for manufacturing nano-circuit board. ADVANTAGE - The device has simple structure, convenient assembly and installation, and efficient operation application, so that production cost is one tenth of the existing production device. The whole working process is free of pollution, no waste gas, and no waste water discharge. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a device.
