- 21. The heat sink assembly of claim 13 wherein said folded fin member is comprised of material selected from the group including aluminum, copper, brass, a zinc-aluminum die cast, and a zinc alloy material.
- 22. The heat sink assembly of claim 14 wherein said slug is comprised of material selected from the group including aluminum, copper, brass, a zinc-aluminum die cast, and a zinc alloy material.
- 23. The heat sink assembly of claim 14 further comprising a thermal interface material disposed on at least one surface of said slug.
- 24. The heat sink assembly of claim 23 wherein said thermoelectric material is selected from the group consisting of a thermoelectric material and a thermoionic material.
- 25. The heatsink assembly of claim 14 wherein said slug is disposed in a generally non-vertical position.
- 26. The heatsink assembly of claim 13 wherein said folded fin member includes a portion disposed in a generally non-vertical position.
- 27. The heatsink assembly of claim 13 wherein said folded fin member includes at least one section disposed at a different height than another section.
- 28. A method of producing a folded fin heatsink member comprising:
providing a plurality of holes in a piece of material; aligning said piece of material; punching a fold into said piece of material; retracting the folded fin; and separating the folded fin from the remaining material.
- 29. The method of claim 28 wherein said aligning comprises locating an index hole in said material and using said index hole as a reference point.
- 30. The method of claim 29 wherein said aligning further comprises aligning said material between a stripper plate and an upper die.
- 31. The method of claim 28 wherein said punching includes lowering an upper die to be adjacent the material.
- 32. The method of claim 31 wherein said punching includes raising a die block and fin forming punch.
- 33. The method of claim 32 wherein said punching further comprises punching said fold into a cavity of said upper die.
- 34. The method of claim 33 wherein said punching further comprises lowering said die block and fin forming punch.
- 35. The method of claim 34 wherein said punching further comprises raising the upper die.
- 36. An apparatus for producing a folded fin heatsink member comprising:
an upper die; a pilot pin movably disposed within said upper die; a stripper plate disposed below said upper die, said stripper plate capable of supporting a piece of material to be formed into a folded fin heatsink member; a die block disposed beneath said stripper plate; and a forming punch extending from said die block.
- 37. The apparatus of claim 36 further comprising a recess formed in said upper die.
- 38. The apparatus of claim 37 wherein said upper die movable between a first upper die position and a second upper die position.
- 39. The apparatus of claim 37 wherein said stripper plate includes an aperture disposed therethrough.
