Abstract
The present invention provides protection from electromagnetic interference and electrostatic discharge. The invention teaches a shielding conductor surface enclosure, an interior shielding conductor plane, a contact conductor from the shielding conductor plane and the shielding conductor surface enclosure, a path for electromagnetic signals to pass through a shielding conductor plane, a filter network, and an electrostatic voltage clamp. Protection is provided by filtering the incoming signals, electrically coupling the signals of an undesired bandwidth to a shield barrier, and electrically coupling signals of an undesired voltage to a shield barrier. The shield surface is physically differentiated from the ground plane surface.
