ABSTRACT:
A pattern of electrodes, with electrical lead lines to the electrodes, are arried by a thin-film membrane mounted on a frame. The pattern corresponds to a test point pattern on a circuit to be tested. The lead lines go to edge connectors on the frame. In order to test a circuit, the membrane is pushed against the test points by air pressure, such that capacitive coupling occurs between the electrodes and the test points.
