Patent ID: 7316060

Claim:
A system for populating a circuit board with a three dimensional array of semiconductor chips comprising: a) a plurality of chip carriers attachable to a circuit board with space for a chip to be positioned directly on said circuit board beneath each chip carrier as well as for positioning a chip on top of said chip carrier to thereby create a three dimensional array of chips on said circuit board; and b) a pallet for holding and moving said plurality of chip carriers during a circuit board assembly process, said pallet having a matrix of chambers in a frame form with the chambers being open at least at a top side of said pallet, each chamber being formed to hold a chip carrier during the circuit board assembly process, said chip carriers being positioned in each of said chambers of the pallet with a top, chip receiving side, of said chip carrier facing out from the top of said pallet to thereby make said top side of said chip carrier accessible during the circuit board assembly process.
