Abstract:
1. A bonding system for bonding a heat sink and a printed circuit assembly together, said bonding system comprising: an adhesive applicator having a first compliant surface and an opposing second surface, the first compliant surface being sized and shaped to receive an adhesive layer; a pressure applicator engaging the adhesive applicator, a first surface of the pressure applicator engaging the second surface of the adhesive applicator and being operative to apply pressure to the adhesive applicator in response to receiving a force via a second surface of the pressure applicator; and a heat sink holder having a recessed portion sized and shaped to receive a heat sink and to maintain a position of the heat sink while the printed circuit assembly and the heat sink are being bonded together, wherein: the first compliant surface exhibits a curved shape when a compressive force is not applied thereto, the first compliant surface being further configured to deform when a compressive force is applied thereto, and to regain the curved shape when the compressive force is removed; the adhesive applicator has suction holes formed therethrough for providing suction to hold the adhesive layer; resilient members are attached to the heat sink holder for urging the pressure applicator away from the heat sink holder; guide pins extend from the first surface of the pressure applicator; and the heat sink holder has receptive holes for receiving said guide pins such that insertion of said guide pins into said receptive holes aligns said pressure applicator with said heat sink holder.
