Abstract:
An assembly comprising:a circuit board having a conductive surface capable of dissipating charge;a component that produces heat mounted on the circuit board;a thermally conductive adjacent structure for conducting heat produced by the component away from the component, the thermally conductive adjacent structure having a conductive surface capable of dissipating charge; anda composite thermal interface pad in thermal contact with the component and the thermally conductive adjacent structure, for conducting heat from the component to the thermally conductive adjacent structure, the composite thermal interface pad comprising:a template formed from a resilient material and having cavities formed therein, including a series of cavities formed proximate a perimeter of the template; andpliable non-resilient material provided within the cavities, wherein the pliable non-resilient material remains pliable and non-resilient when the composite thermal interface pad is conducting heat away from the component, and the pliable non-resilient material within the series of cavities proximate the perimeter of the template is electrically conductive and in electrical contact with the conductive surfaces of the component and the adjacent structure.
