Abstract:
A method of preparing thermally conductive mechanically compliant pads comprising the steps of:(a) preparing a mixture of: (1) a quantity of a gallium and/or indium containing alloy which is in liquid state temperatures below 120Â° C.; (2) a thermally conductive particulate solid consisting essentially of boron nitride; (b) mechanically blending said mixture to cause the surfaces of said particulate to become wetted with said liquid alloy to form a homogeneous paste wherein said liquid alloy encapsulates individual of said boron nitride particles; (c) combining said paste with a quantity of a flowable plastic resin material to form a thermally conductive mass with said thermally conductive mass comprising from between about 10% and 90% by volume of metal coated particulate, balance flowable plastic resin.
