Abstract

See full text

A thermally conductive conformable interface pad for inter-position between a heat generating solid state electronic device and a heat sinking surface. The interface comprises a laminate of at least two layers, including a relatively soft conformable body layer with at least one surface consisting of an integrally bonded anti-blocking layer. The conformable body layer preferably comprises a thermally stable wax consisting of an alkyl substituted poly (hydro, methyl-siloxane) wax and a thermally conductive particulate solid, while the anti-blocking layer may comprise a mixture of an alkyl substituted poly (hydro, methyl-siloxane) wax and a silicone wax, a glassy polyester layer, or a cross-linked acrylic layer.
