DEVICE CAPABLE OF THERMALLY COOLING WHILE ELECTRICALLY INSULATING

摘要

The present disclosure relates to a device for thermally cooling while electrically insulating. The device contains a first adhesive layer, polyimide substrate, a second adhesive layer and a heat sink. The first adhesive layer and the second adhesive layer are a vinyl or acrylic polymer. The polyimide substrate has at least two polyimide layers. The polyimide layers are derived from at least one aromatic dianhydride and at least one aromatic diamine. The adhesive layers and the polyimide layers may contain thermally conductive fillers, light absorbing pigments or mixtures of both.
