Abstract: A test pattern membrane test method uses a test pattern membrane to test the capacitive sensors of a device. The device is placed in the test fixture. The capacitive sensors are read without the test pattern membrane, storing as a set of baseline measurements. The test pattern membrane is placed on the unit to be tested. The test pattern membrane has a plurality of conductive areas on a non-conductive substrate. The conductive areas are arranged in a pattern that corresponds to the pattern of capacitive sensors. The sensors are read again to obtain a set of stimulated measurements. Differences for each of the sensors are determined between the sensor readings with and without the test pattern membrane in place. This difference is compared to a threshold. A sensor is considered to be functioning properly if the difference value is greater than the sensor's threshold value.

Abstract: A capacitive touch sensor has a clear top plastic film and graphics or other designs disposed on its reverse side. Only the bare plastic substrate is exposed to the environment and user wear. Non-conductive color inks are used in printing the graphics so that any printed capacitive sensors in contact behind will not be short circuited or desensitized. A silk-screened base color layer with a print-free margin left all around its edges allows a later application of adhesive to grip a more durable surface underneath. Capacitive touch sensors are deposited on a bottom plastic film with silvered conductive inks. The printed capacitive sensors on film are fastened with a silk-screen applied liquid water-based adhesive and face the graphics printed side of the first plastic film. A final overcoat of adhesive is applied to the bare backside of the bottom plastic film for final assembly to a frame or chassis.
