Heat spreader assemblies are disclosed that include a heat spreader component, at least one coupling layer, and at least one thermally conductive layer, wherein the heat spreader component is coupled to the at least one thermally conductive layer through the at least one coupling layer. In some instances, heat spreader assemblies include an aluminum-based heat spreader component, at least one coupling layer, wherein the coupling layer comprises zinc, a zinc-based material, tin, a tin-based material or a combination thereof, and at least one thermally conductive layer comprising nickel, wherein the heat spreader component is coupled to the at least one thermally conductive layer through the at least one coupling layer. Methods of forming heat spreader assemblies are also disclosed that include providing a heat spreader component, wherein the heat spreader component comprises a top surface, a bottom surface and at least one heat spreader material; providing at least one coupling material, wherein the coupling material is directly deposited onto the bottom surface of the heat spreader component; and depositing, applying or coating at least one thermally conductive coating, film or layer on at least part of the bottom surface of the heat spreader component. In several embodiments, heat spreader component comprises a native oxide layer, an oxide barrier layer or a combination thereof that is removed before application of the at least one coupling material. |
