Device and method of wire wrap (or other electrical interconnection between I.C. sockets) checkout
First Claim
1. A reuseable plug-in test module for testing wire wrap board electrically interconnected circuits which comprises:
- a base made of electrically insulating material;
a pair of rows of linearly aligned equally spaced socket pins secured in said base and insulated from each other;
said pins extending above and below said base,a plurality of visual light emitting means electrically connected with one each of said spaced socket pins above said base;
an electrical conductor common to each of said light emitting means;
a resistor means electrically connected between each said light emitting means and said common electrical conductor;
an electrical conductor post connected with each end of said common electrical conductor;
a thin insulator board secured above the upper ends of said socket pins in said base and supported thereby,said insulator board supporting said plurality of visual light emitting means, said resistor means, said common electrical conductor, and said electrical posts connected with each end of said common electrical conductor.

Abstract
This invention is directed to a test module for and method of testing integrated circuit connections (i.e., wire wrap, multilayer printed circuit boards, etc.) to determine whether or not the circuits are correctly wired and whether or not there are any short circuits or broken connections, as well as any other electrical problems. The system confirms the validity of the electrical interconnections by a visual comparison of the lighted light emitting diodes and the assembly plan; if the correct comparison is not made, an error in the manufacturing process is indicated. Failure of any of the expected light emitting diodes to light indicates missing or electrically bad connections; extra lighted light emitting diodes indicate extraneous connections or short circuits on the board.
