Abstract:
1. An assembly comprising: a stiffener, the stiffener having a surface comprising a first region and a second region; a circuit substrate, the circuit substrate covering at least a portion of the first region of the stiffener; an integrated circuit chip, the integrated circuit chip overlying at least a portion of each of the first and second regions of the stiffener; a plurality of signal solder bumps, each of the plurality of signal solder bumps contacting the integrated circuit chip and the circuit substrate; and a plurality of thermally conductive features, each of the plurality of thermally conductive features being disposed between, and being metallurgically bonded to, the integrated circuit chip and the second region of the stiffener; wherein the circuit substrate has an aperture formed therethrough over the second region; and wherein the thermally conductive features are arranged within the aperture in the form of an array of thermally conductive features.
