▎ 摘　　要

NOVELTY - Copper-based heat dissipation and vibration damping composite film comprises first release film layer, thermal conductive adhesive layer, first black Mylar (RTM: Polyester film) layer, first double-sided adhesive layer, copper foil layer, second double-sided adhesive layer, second black Mylar (RTM: Polyester film) layer, third double-sided adhesive layer and second release film layer, which are orderly arranged from up to down and are matched with each other; the thermal conductive adhesive layer is pasted on one side of the first black Mylar (RTM: Polyester film) layer and the thermal conductive adhesive layer does not completely cover the first black Mylar (RTM: Polyester film) layer; V-shaped grooves are provided on one side edge of the thermal conductive adhesive layer. USE - The composite film is useful in electrical component. ADVANTAGE - The composite film: has high insulation, flame retardancy, shielding and abrasion resistance, high strength, high heat conduction and heat dissipation capabilities; is not easy to be damaged; and is not easy to crack.
