Alignment Guide

Module insertion in printed-circuit board holes is facilitated by a guide used during initial setup, to align the holes relative to the insertion tool head.

A base mounting a locating pin is fastened to the head of an automated module insertion machine such as the SPI Mark IV DIP Insertion Machine marketed by Synergistic Products, Inc., Irvine, California. A circuit card is placed in a holding fixture and the locking screw on the base is loosened to release the locating pin. The holding fixture is adjusted until the pin drops into, and is centered in, an empty hole. hole.

The holding fixture is micrometer adjusted in both the Y direction and X direction to center the pin in the first hole. The normal machine controls are used to bring the pin from a hole near one corner of the card to another hole near the front-to-back opposite corner. The holding fixture is then micrometer adjusted in the X direction only to center the pin in the second hole.
