Test fixture wiring integrity verification device
First Claim
1. In the method of orienting test probes in a wiring test system to engage contact points on a circuit board, the steps that includea) providing a wiring integrity verification plate means the plate means being a thin insulative base plate, and providing multiple contact pads to have upwardly domed surfaces and the pads and leads attached to the plate,b) orienting each lead to extend between and interconnect two of the contact pads, whereby multiple circuit sections are formed on the plate, each circuit section including two pads interconnected by a lead,c) and locating the two pads of each circuit section to be contacted by two probes of the wiring test system for providing an electrical continuity test via that circuit section, when those two probes are correctly located relative to contact points on a production circuit board for testing the production circuit board,d) and, for the majority of pads, providing the spacing between an interconnected pair of pads to be greater than the spacing between either pad of the pair and another nearby pad on the plate.

Abstract
A wiring test system in which test probes are to be oriented to engage contact points on a production circuit board, a wiring integrity verification plate comprising, in combination: a thin insulative base plate, multiple contact pads and leads attached to the plate; each of the leads extending between and interconnecting two of the contact pads, whereby multiple circuit sections are formed on the board, each circuit section including two pads interconnected by a lead; the two pads of each circuit section respectively located to be contacted by the probes of the wiring test system for providing an electrical continuity test via that circuit section, when those two probes are correctly located relative to contact points on production circuit board for testing the production circuit board.
