Method and apparatus for reducing electromagnetic emissions from electronic circuits

摘要

An electronic circuit ( 10 ) comprising at least one electrical component ( 12 ) and at least one grounding point ( 16 ) is provided that includes a first layer of non-conductive coating ( 18 ) and a second layer of conductive coating ( 20 ). The non-conductive coating ( 18 ) is applied over the electrical component ( 12 ) in such a manner that the grounding point ( 16 ) remains uncoated. The conductive coating ( 20 ) is applied over the non-conductive coating ( 18 ) and the grounding point ( 16 ) so as to ground the conductive coating ( 20 ). The conductive coating ( 20 ) thus shields the electrical component ( 12 ) to thereby reduce electromagnetic emissions from the electronic circuit ( 10 ). Various exemplary embodiments of the coated electronic circuit and associated method are provided.
