ABSTRACT:
An apparatus for checking electrical microprinted circuits comprising an insulating body formed with a number of openings in which electrodes are mounted and which can be aligned with circuit points on the printed circuit board and with electrodes mounted in each of the openings in the insulated body above a hollow space formed between the surface of the printed circuit board and the end of the electrodes with gas such as air or other material being within the opening such that when a voltage is applied between electrodes connected to opposite ends of a common printed circuit conductor discharge will occur through the gas to the electrodes thus allowing current to flow which can be detected to measure the conductivity of the printed circuit path.
