Abstract: A method of aligning integrated circuit chips on a substrate, such as a circuit board, for joinder by means of solder bumps. A stencil mask forms a transfer plate with holes in the same locations as solder bumps on the circuit board. The transfer plate is used to lift integrated circuit chips with metal contact regions loosely seated in holes in another mask, forming a die array plate. Vacuum is applied behind the transfer plate to pick up chips which have been seated on the die array plate. The chips are then moved over the circuit board and deposited onto the solder bumps previously formed and then joined thereto. The transfer plate and the die array plate have hole patterns in the same locations as yet another stencil mask, used for solder deposition in forming the solder bumps.
