Abstract: A sealed pouch constructed of thermally conductive flexible material containing a low melting point, thermally conductive material is placed between two components that require thermal continuity. This assembly is then loaded in compression and heated to the melting point of the low melting point, thermally conductive material, which then melts within the sealed pouch, and conforms to the shape of the two components. The sealed pouch also may contain a springy material made of a metal, or a solder compatible plastic or organic to help maintain shape of the pouch in some applications.

Abstract: A first printed circuit board is built including one or more openings configured to correspond to heat-generating devices attached to a second printed circuit board. The first and second printed circuit boards are aligned with each other and a heat sink, such that the heat sink is thermally coupled with heat-generating electronic devices on both the first and second printed circuit boards. Heat-generating devices are thermally coupled with a thermal pad on one or more of the printed circuit boards. The thermal pad is then thermally coupled with the heat sink. Optionally, the first and second printed circuit boards may be electrically coupled with each other through an electrical connector.
