ABSTRACT:
A tapered thermal substrate for transferring heat generated from a heat source to a heat sink comprising a composite core of parallel layers of thermally conductive fibers, the core having a tapered edge that maximizes fiber end exposure to the heat source or sink. The tapered edge is comprised of at least one angled surface formed by machining the composite core. A copper thermal tab is plated to each angled surface and machined to a desired size and shape to provide a contact surface for the heat source or sink and a means for facilitating transfer of generated heat to and from the fiber ends. A flashing of a thin coating of copper and nickel over the composite core and each copper thermal tab is also provided to environmentally seal the composite core.
