  • Patent number: 5825625
    Abstract: A heat conductive substrate is mounted within a through-opening of a printed circuit board. An integrated circuit then is mounted to one side of the heat conductive substrate, while a heat sink is fixed in thermal contact to the other side of the substrate. There is no direct thermal contact between the IC and the PC board. The substrate is mounted to an undersurface of the PC board and concentrically spaced from the PC board within the opening. An air gap occurs between the substrate and the PC board within the opening to substantially reduce heat conductivity into the PC board.

  • Patent number: 5825623
    Abstract: Encapsulated thermally enhanced (TE) and electrically and thermally enhanced (ETE) integrated circuit assemblies that include bulky thermally conductive heat sinks are disclosed. The integrated circuit assemblies are configured to prevent the formation of pinholes and IC package warpage without adding bulk or additional structures. The assemblies are repositioned, through an offset in the bonding fingers of the leadframe, so that the rates of mold flow in the two halves of the mold cavity are substantially balanced. The repositioning of the assemblies also substantially balances the amount of mold material in the mold halves, which prevents warpage in a finished IC package.
