Printed Circuit Module Reforming Tool

The figures show a tool for altering the pitch of pins of printed-circuit modules, so that they are usable with boards having sockets of a different pitch.

The tool consists of a number of tubes 1 extending vertically from a block 2 mounted on a base plate 3. The number of tubes 1 equals the number of pins on the module to be re-formed and they are spaced with the desired pitch of the pins. The tubes 1 project through correspondingly positioned holes in a plate 4 which is slidably mounted on guide bars 5. The plate 4 is shown at the bottom of its stroke in Figs. 1 and 2 and almost at the top in Fig. 3.

To use the tool, the pins 6 of a module 7 to be re-formed are inserted in the open ends of the tubes 1, as shown in Fig. 2. This insertion is facilitated in practice by using two comb-like spacers with teeth of the same pitch as that of the pins 6. When used at right angles to each other at the top of the tubes 1, the spacers hold the tubes correctly spaced in rows and columns so that the pins 6 of the module 7 can be inserted. The spacer-combs which have been omitted from the figures for clarity are then removed.

The re-forming of the pins 6 to the pitch required to fit the sockets in the board is achieved simply by raising the plate 4 to its upper position as shown in Fig. 3. Continued movement of plate 4 to the end of its stroke ejects the re- formed module 7 from the tubes 1.
