Control device for an apparatus for testing electrical function of wiring patterns

Abstract

Abstract The invention is based on the object of providing the possibility for the simplest possible electrode shapes for further miniaturisation in such a two-electrode arrangement. <??>To test circuit boards, a contactless plasma contact-making arrangement is proposed in which in each case contact can be made with two selected test points of a wiring array via the associated gas discharge channels and their electrodes. The test points are selected by control gas discharges which are generated by applying a sufficiently high voltage between the electrodes. A current flow which can be utilised for test purposes is generated by applying a voltage between the gas discharges when the test points are conductively connected. <IMAGE>
