▎ 摘　　要

NOVELTY - The method involves (a) injecting electromagnetic wave reflective material, electromagnetic wave absorbing material, and an electrolyte solution (120) into a plating bath (130), (b) mounting a heat radiation sheet (140) in plating bath, and (c) forming an electromagnetic wave shielding layer on heat radiation sheet by electroplating an electromagnetic wave reflecting material and electromagnetic wave absorbing material on heat radiation sheet. The heat radiation sheet includes natural graphite, artificial graphite, and/or expanded graphite. The electromagnetic shielding layer exhibits heat dissipation. The material that reflects electromagnetic waves is metal. The electromagnetic wave absorbing material is graphene oxide and/or MXene. When ultrasonic waves are applied to plating bath, the electromagnetic wave reflective material is plated on heat radiation sheet in form of electromagnetic wave shielding composite bonded to surface of wave absorbing material. USE - The method is useful for manufacturing composite plated heat dissipation sheet using device (claimed). ADVANTAGE - The method enables to manufacture composite plated heat dissipation sheet with excellent performance by performing powder electroplating in order to increase the electromagnetic wave shielding performance in the high frequency region. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: composite plated heat-dissipation sheet manufactured by the above method; and device comprising a plating bath in which an electromagnetic wave reflective material, an electromagnetic wave absorbing material, and an electrolyte are injected, a cathode in which an anode (150) and a heat radiation sheet are mounted, and an ultrasonic application unit that combines an electromagnetic wave reflective material with an electromagnetic wave absorbing material to form an electromagnetic wave shielding complex (113). DESCRIPTION OF DRAWING(S) - The drawing explain a method for manufacturing composite plated heat dissipation sheet. 113Electromagnetic wave shielding complex 120Electrolyte solution 130Plating bath 140Heat radiation sheet 150Anode
