Abstract
In one form of the invention, an electronic device having a conformally coated Faraday cage, comprising a non-conductive conformal layer (30) substantially coveting the electronic device (10, 12) and a conductive conformal layer (34) substantially coveting the non-conductive conformal layer.
Claims11
A method of coating an electronic device, comprising the steps of:
- (a) applying a non-conductive conformal layer substantially covering said electronic device;
- and
- (b) applying a conductive conformal layer substantially coveting said non-conductive conformal layer, wherein said conductive conformal layer is formed by addition of a conductive additive to a material of substantially the same composition as a material used to form said non-conductive conformal layer.
A method of grounding an electronic circuit board, comprising the steps of:
- (a) applying a non-conductive conformal layer substantially coveting said electronic circuit board;
- (b) applying a conductive conformal layer substantially coveting said non-conductive conformal layer, wherein said conductive conformal layer is formed by addition of a conductive additive to a material of substantially the same composition as a material used to form said non-conductive conformal layer;
- (c) making electrical contact between said conductive conformal layer and a ground plane of said electronic circuit board;
- and
- (d) operatively coupling said ground plane to a ground potential.
