ABSTRACT:
A protective heat sinking device for an electronic circuit card having upper and lower layers of an air-impermeable polymer material forming an air-impermeable bag. A metallic foil having high thermal conductivity is inserted between the upper layer of air-impermeable polymer material and the top surface of the electronic circuit card. The air-impermeable bag has an open side into which the circuit card is inserted. The bag is evacuated to produce a conformal vacuum seal in which the upper and lower layers of air-impermeable polymer material and the metallic foil are drawn down onto the surface of the circuit card and form a conformal protective cover about its contours. A layer of electrically insulating material may be added between the metallic foil and an upper face of the circuit card to electronically insulate the metallic foil from the circuit components mounted on the upper face of the circuit card contained within the protective heat sinking device. A method for conformally sealing a circuit card in the protective heat sinking device is also provided.
