Abstract
The invention relates to an electrically conductive unit having electrically conductive paths, which are directly or indirectly applied onto a case for creating a screening against electromagnetic radiation and for the draining of electrical currents.
Claims19
A device for reducing electromagnetic radiation within a case, the device comprising:
- at least one surface within the case, wherein the surface includes at least one bridge having a printing base surface formed thereon;
- and
- an electrically conductive layer disposed on at least selected portions of the surface and arranged to shield against electromagnetic radiation and carry electrical currents, the electrically conductive layer comprising a plurality of electrically conductive paths, at least one of said paths being disposed on the printing base surface of the bridge.
A method for reducing electromagnetic radiation within a case, the method comprising:
- providing a case having at least one surface therein, and further providing at least one bridge connected to the surface, the bridge having a printing base surface formed thereon;
- and
- selectively forming an electrically conductive layer on at least portions of the surface, the electrically conductive layer being arranged to shield against electromagnetic radiation and carry electrical currents through a plurality of electrically conductive paths, at least one of said electrically conductive paths being formed on the printing base surface of said bridge.
A device for reducing electromagnetic radiation within a case comprising:
- at least one surface within the case;
- an electrically conductive layer disposed on at least selected portions of the surface and arranged to shield against electromagnetic radiation, said electrically conductive layer comprising a plurality of electrically conductive paths which vary from one another in regard to at least one specified physical dimension, said specified dimension being selected from a group comprising width and thickness;
- and
- said surface includes at least one bridge having a printing base surface formed thereon, and at least one of said electrically conductive paths is disposed on the printing base surface of said bridge.
