Abstract:
1. A heat-dissipating device, comprising: a graphite laminate planar body having a top surface, a bottom surface, a pair of opposing first lateral sides interconnecting the top surface and the bottom surface, a pair of second opposing lateral sides also interconnecting the top surface and the bottom surface, the graphite laminate planar body extending along an x-y plane, and the top surface and the bottom surface extending parallel to the x-y plane; a first electroplated metal layer formed on the top surface of the graphite laminate planar body, the first electroplated metal layer comprising a first metal; a second electroplated metal layer formed on the first electroplated metal layer, the second electroplated metal layer comprising a second metal different than the first metal, wherein a total thickness of the first electroplated metal layer and the second electroplated metal layer have a thickness of not less than about 1 μm; an adhesive adhered to the bottom surface of the graphite laminate planar body; and an insulation film attached the second electroplated metal layer, wherein said first and second electroplated metal layers are interposed between the insulation film and the graphite laminate planar body planar body, whereby the first and second electroplated metal layers conduct heat generated from an electronic component adhered to the adhesive to ambient air along the x-y plane of the graphite laminate planar body and provides the heat-dissipating device a heat dissipation efficiency greater than that which would be provided by the graphite laminate planar body alone and further provides the graphite laminate planar body increased surface hardness and rigidity over that which would exist in the absence of the electroplated metal layers.
