This article describes an apparatus to insert and re-solder a zero- insertion-force-type connector, or the like, into a circuit board without adversely affecting the adjacent soldered connections. The apparatus consists of connector gripper jaws 3 and an evacuated probe 4 that is connected to an electrical power supply. The gripper jaws 3 grasp a connector 5 onto which a solder ring 6 has been preattached. The solder ring 6 is of a volume to correctly fill the targeted plated through hole (PTH) 8. The gripper jaws 3 grasp the connector 5 at a position (Fig. 1) which, when the solder ring 6 is melted, will form a ball 9 contacting both the jaws and PTH (Fig. 2). The heat to melt the solder ring is the result of passing current through the connector from the jaws to the probe.
