A system for use between a heat generating electronic device having a die having a shape placed thereon and a heat sink, includes a thermally conductive slug having a plurality of edges; a plurality of discrete strips each of the strips having a proximal end attaching to one of the edges of the thermally conductive slug, a distal end wherein the distal end is rigid for attachment to the heat sink, a flexible portion between the distal end and the thermally conductive slug wherein the slug may move as the electronic device moves and wherein the strips are comprised of two of more discrete layers, or strands that create a braid.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A system for use between a heat generating electronic device having a die having a shape placed thereon and a heat sink, said system comprising; a thermally conductive slug having a plurality of edges; a plurality of discrete strips each of said strips having a proximal end attaching to one of said edges of said thermally conductive slug, a distal end wherein said distal end is rigid for attachment to said heat sink, a flexible portion between said distal end and said thermally conductive slug wherein said slug may move as said electronic device moves and wherein said strips are comprised of two of more discrete layers, or strands that create a braid, a frame for disposal between said discrete strips and said slug, said frame having a plurality of sides corresponding to the same number of strips, each of said distal ends of said strips attaching to a side of the frame.
2. The system of claim 1 wherein said strips include strands only.
3. The system of claim 1 wherein said strands include two or more strands made of copper, silver, aluminum, or graphite.
4. The system of claim 1 wherein said strips include layers only.
5. The system of claim 1 wherein said layers include two or more layers made of copper, silver, aluminum, or graphite.
6. The system of claim 1 further comprising a spring biasing said slug for urging said slug against said die.
7. The system of claim 1 wherein said frame, said strips, and said slug comprise a preform.
8. The system of claim 1 further comprising a spring abutting said slug.
9. A system for dissipating heat, said system comprising; a heat generating electronic device; a heat sink; and an assembly disposed between said heat sink and said electronic device, said assembly including: a thermally conductive slug abutting said heat generating electronic device and having a plurality of edges; a plurality of discrete strips each of said strips having a proximal end attaching to one of said edges of said thermally conductive slug, a distal end wherein said distal end is rigid for attachment to said heat sink, and a flexible portion between said distal end and said thermally conductive slug wherein said slug may move as said electronic device moves and wherein said strips are comprised of two of more discrete layers, or strands that create a braid, a frame for disposal between said discrete strips and said slug, said frame having a plurality of sides corresponding to the same number of strips, each of said distal ends of said strips attaching to a side of the frame.
10. The system of claim 9 wherein said strips include strands only.
11. The system of claim 9 wherein said strands include two or more strands made of copper, silver, aluminum, or graphite.
12. The system of claim 9 wherein said strips include layers only wherein said layers include two or more layers made of copper, silver, aluminum, or graphite.
13. The system of claim 9 further comprising a spring biasing said slug for urging said slug against said die.
14. The system of claim 9 further comprising a die disposed atop said heat generating electronic device between said heat generating electronic device and said slug.
15. The system of claim 14 further comprising a thermal layer disposed between said heat generating electronic device and said slug.
16. The system of claim 9 wherein said frame, said strips, and said slug comprise a preform.
17. The system of claim 9 further comprising a spring abutting said slug.
18. The system of claim 9 wherein said preform is preattached to either of said heat generating electronic device or said heat sink.
