Abstract
Abstract A pattern of electrodes, with electrical lead lines to the electrodes, arearried 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.

A method of making a flexible membrane tester for a planar electrical circuit including the steps of: preparing a frame to hold said membrane; affixing a relatively thin flexible membrane to said frame; depositing a plurality of electrodes on one side of said membrane in a desired pattern; forming respective holes through said membrane concentric with said electrodes, but of smaller size than said electrodes; depositing electrical lead lines on the opposite side of the membrane from said electrodes, one for each electrode, and extending from a respective electrode to another region of said membrane; and forming a high-dielectric layer on the side of each electrode opposite to the membrane side of the electrode.
