Abstract
Embodiments of the present invention provide an electro-magnetic suppressive structure. The electro-magnetic suppressive structure comprises a cover portion and an integrally formed conductive portion.
Claims17
An electro-magnetic suppressive structure comprising:
- a cover portion for protecting a printed circuit assembly (PCA) against physical damage during handling, said cover portion comprising an openable portion for selectively exposing components underlying the cover, wherein said cover portion is coupled to the PCA by electrically insulative hardware;
- and
- a conductive plane portion integrally formed about said cover portion for protecting a printed circuit assembly (PCA) against electrical damage during operation by forming an electro-magnetic interference (EMI) image plane, wherein said conductive plane portion is a plane regardless of the surface it is covering, said conductive portion comprising;
- an openable portion;
- a plane portion;
- and
- an elongated portion electrically coupled to said plane portion, said elongated portion comprising an inductive connection for a time varying signal on said conductive portion.
