Insertion/extraction tool for substrate package

Abstract

Insertion/extraction tool for inserting a substrate into, and extracting a substrate from, a socket assembly has a frame assembly containing force multiplying means and a yoke. Spaced-apart yoke arms extend from the yoke and have ends which will engage either the socket assembly or the underside of the substrate. First frame arms are fixed to the frame and have ends which are spaced from the ends of the yoke arms. Second frame arms are slidably mounted on the frame assembly for movement between extended positions and retracted positions. When inserting the substrate, the yoke arms are located between the underside of the socket and the surface of the circuit board on which the socket is mounted. The frame is moved towards the end of the yoke arms so that the first frame arms push the substrate into assembled relationship with the socket. When the tool is used for extraction, the second frame arms are moved to their extended positions and are located on the surface of the circuit board. The end of the yoke arms are positioned between the underside of the substrate and the upper surface of the socket assembly, The yoke is then moved upwardly by the force applying means and away from the circuit board so that the yoke arms pull the substrate upwardly and from the socket assembly.
