Abstract
A functional EMI containment plug or assembly useful to block an opening or hole in an electronics cabinet or enclosure so as to provide EMI containment. Functionality is achieved by combining a membrane with a circuit board. The EMC assembly functions as a circuit board-based membrane keyboard, which includes tactile switches a user can press to actuate a circuit board function. The switches may be a dome switch that has collapsing action (e.g., amount of travel), and the thickness of the membrane layers placed on top of the front of the circuit board are matched to the chosen dome switch to allow a proper amount of travel. The layers of the membrane act as an EMI shield. In one embodiment, the membrane includes a metal foil layer and a conductive material layer, and the combination of foil and conductive layers of the membrane act to provide a shield for EMI.
