  • Patent number: 11778739
    Abstract: A thermally conductive board includes a metal substrate, a metal layer, a thermal conductive insulating polymer layer, and a ceramic material layer. The thermal conductive insulating polymer layer is located between the metal layer and the metal substrate. The ceramic material layer includes an upper ceramic layer or a lower ceramic layer, or includes both the upper ceramic layer and the lower ceramic layer. The upper ceramic layer is disposed between the metal layer and the thermal conductive insulating polymer layer, and the lower ceramic layer is disposed between the thermal conductive insulating polymer layer and the metal substrate.
    Type: Grant
    Filed: March 1, 2021
    Date of Patent: October 3, 2023
    Assignee: POLYTRONICS TECHNOLOGY CORP.

  • Patent number: 11511521
    Abstract: An insulated metal substrate (IMS) and a method for manufacturing the same are disclosed. The IMS includes an electrically conductive line pattern layer, an encapsulation layer, a first adhesive layer, a second adhesive layer, and a heat sink element. The encapsulation layer fills a gap between a plurality of electrically conductive lines of the electrically conductive line pattern layer. An upper surface of the encapsulation layer is flush with an upper surface of the electrically conductive line pattern layer. The first and second adhesive layer are disposed between the electrically conductive line pattern layer and the heat sink element. A bonding strength between the first adhesive layer and the second adhesive layer is greater than 80 kg/cm2.
