Insertion Removal Tool for Integrated Circuit Modules

This tool enables the insertion and removal of 14-16 pin line integrated circuit modules in close quarters from sockets or matrix boards, without damaging the pins in any way.

The hand-held tool 20 is shown in an illustrative cross-section about the longitudinal center line of the module with which it is used. A body member 22 is about as wide as the length of the module and has a rectangular recess in the lower end defined by a lower wall 24, and a corresponding wall in the upper half of the body member, not shown. The spacing between the walls is of the order of the width of the module, whereby the tool 20 can be positioned completely over the module. The depth of the recess is large enough to accommodate a pressure plate 26 and the module including the pins. The pressure plate 26 is secured to one end of a plunger rod 28. The other end of the rod 28 is threaded into a knob or cap 30 having an undercut portion 32. The effective length of the plunger rod is adjusted by this threaded connection, which also permits alternate subassemblies of plunger rod and pressure plate to be interchanged for different sizes and types of modules.

For modules having Braille-like identification dots, the pressure plate is alternately fitted with two or more bosses 33 strategically placed. The body member 22 is bored centrally for the plunger rod 28, the undercut portion 32, and a spring 34 for urging the pressure plate 26 on the end of the rod 28 to the uppermost position; the pressure plate 26 is shown for clarity as though partially depressed. Such partial depression is effective in the...
