1. An assembly for forming a re-attachable, precast curable thermal interface adhesive layer of a specified shape and specified thickness, the assembly comprising:
a curable thermal interface adhesive layer applied onto a first heat sink; a dummy substrate including an outer surface that represents a surface of a second heat sink; said curable thermal interface adhesive layer and the first heat sink being applied onto the outer surface of the dummy substrate, and said outer surface forming the thermal interface adhesive layer into said specified shape matching a shape of the outer surface of the second heat sink and with said specified thickness as said adhesive layer cures; and a release layer releasably applied onto the outer surface of the dummy substrate prior to said thermal interface adhesive layer being applied thereto, and located between the outer surface of the dummy substrate and the thermal interface adhesive layer to facilitate separating the thermal interface adhesive from the dummy substrate with the first heat sink fixed to the thermal interface adhesive layer, thereby enabling said thermal interface adhesive layer, with the first heat sink fixed thereto, to be mated with said second heat sink.
