ABSTRACT:
An assembly of an electronic device within a chamber defined by a flexible container. The device, which may be a printed circuit board, has signal terminals connected to elongate insulated signal conductors. These conductors pass through a laminate construction wall of the container for connection to an outside electrical conductor. The signal conductors are electrically isolated from an EMI protection layer which forms part of the laminate construction wall. A ground conductor extends through the wall and is separated from the wall by a dielectric spacer to provide a capacitive coupling between the EMI protection layer and the ground conductor. The capacitive coupling produces a desired capacitive effect for shorting certain electrical frequencies from the EMI protection layer to ground. Conveniently, a flat cable provides the signal and ground conductors and the cable extends through a sealed opening of the container.
