Faraday cage
First Claim
1. A Faraday cage comprising:
- a circuit board having an electrical ground;
at least one electronic component electrically connected to the circuit board;
a conductive housing having at least an open end; and
an electrically conductive adhesive having a substrate having numerous passageways through the substrate defined by a plurality of internal surfaces, said internal surfaces defining said passageways having disposed thereon a layer of conductive metal, said passageways being at least partially filled with an adhesive resin, wherein the electrically conductive adhesive electrically mounts the conductive housing to the electrical ground of the circuit board, such that the open end of the conductive housing is disposed over the at least one electronic component, to shield electromagnetic and radio frequency interference.

Abstract
A Faraday cage is provided for EMI/RFI shielding which includes a substrate having an electrical ground; at least one electronic component electrically connected to the substrate; a conductive housing; and an electrically conductive adhesive. The electrically conductive adhesive may be defined by a substrate having numerous passageways through the substrate. The passageways are defined by a plurality of walls of the material making up the substrate. The walls are covered with a layer of conductive metal. The passageways are filled with a non-conductive adhesive resin. The conductive housing is adhesively electrically mounted to the electrical ground of the substrate, over the electronic component, to shield electromagnetic and radio frequency interference.
