Test electrode unit for printed circuit tester - has insulating substrate with test electrode element mounted on side, cross-shaped standard grids with electrodes formed on them, and connecting material

摘要

The electrode unit is divided into several functional regions, each having the same test electrode arrangement. The connecting material, which electrically connects the test electrode together, is applied to the corresp. positions in the functional regions to form compound electrodes. The number of functional regions is given by 4 power n, where n is a whole number, e.g. 1. The connecting material is a multilayer circuit provided in the insulating substrate. An off-grid adaptor may also be provided. USE/ADVANTAGE - Enables highly efficient connection to test circuit of measuring device, even when printed circuit has electrodes to be tested on both sides.
