Terminal Pin Cleaning Tool

This tool removes contaminants of various kinds from terminal pins such as provided on solid-state circuit modules. Such pins are usually provided in the form of closely spaced arrays, and it has been a problem to remove contamination which can occur during manufacture and testing of the modules.

As shown in Fig. 1, the tool comprises a sleeve or length of tool steel tubing 1, hardened to a suitable degree and counterbored or relieved for the greater part of its length to a diameter slightly larger than the pin diameter on which it is to be used. The tip of sleeve 1 is ground to a knife edge as at 3, and this portion of the sleeve has a diameter equal to the pin diameter.

In use, the tool is mounted in a suitable holder, such as a pin vise 5, and is run onto the pins which are to be cleaned, preferably while rotating the tool, as shown in Fig. 2.
