NOVELTY - The utility model claims a multi-layer circuit board structure of combined type 5 G communication, comprising a core plate and a mounting plate, the mounting plate is a U-shaped plate, the mounting plate is provided with a screw rod; one end of the screw rod is fixedly provided with a rotating plate, the rotating plate and the mounting plate outer wall one side contact set; the other end of the screw rod is provided with a bearing; the bearing is set on the mounting plate; the screw rod upper spiral sleeve is provided with two opposite moving plates. Beneficial effects: the vertical bolt bottom is propped against the top end of the core plate, realizing the upper and lower clamping effect; it can realize the mounting or dismounting core plate; greatly accelerates the process of mounting or dismounting; the graphene coating is set between the core plate and the transverse plate; the graphene coating has good thermal conductivity; the graphene coating quickly absorbs the heat on the core plate; then transferring to the transverse plate; the transverse plate is a copper radiating plate, so that the heat is accelerated to dissipate; the device not only can realize the disassembly and installation, but also has good radiating effect.
