Abstract:
1. A system, comprising: an integrated circuit coupled to a circuit board; a heat conducting element having a thermal conductivity of at least 391 W/m*K, the heat conducting element comprising a flexible portion disposed between first and second solid portions; wherein the heat conducting element comprises a plurality of sheets of heat conducting material stacked in a sandwiched configuration; wherein a first end of each of the plurality of sheets of heat conducting material is fused to a first end of another one of the plurality of sheets of heat conducting material to form the first solid portion; and wherein a second end of each of the plurality of sheets of heat conducting material is fused to a second end of another one of the plurality of sheets of heat conducting material to form the second solid portion; the flexible portion having a cross-sectional area approximately equal to a cross-sectional area of the first solid portion; and wherein the first solid portion is coupled to the integrated circuit and the second solid portion is coupled to a heat sink.
