ABSTRACT:
A method for applying pressure to circuit components during a manufacturing operation. The method utilizes a plurality of compressed air pressure cylinders which are supported on a plurality of horizontal arms along different axes over a circuit board. Compressed air is supplied simultaneously to each of the cylinders, and the cylinders force the component onto a bonding position on the circuit board. The method permits heat sinks to be pressed against components located on the circuit board to bond the heat sinks to the components.
