Abstract
Various embodiments provide EMI shields for substrates having at least one electrical component disposed thereon. In one embodiment, an EMI shield generally includes a cover having first and second protrusions and at least one electrically-conductive member disposed along an inner side of the cover. The electrically-conductive member may be compressed generally between the substrate and the cover when the substrate is captured generally between the electrically-conductive member and the first protrusion. In addition, a compressive clamping force may be generated by the engagement of the first protrusion with the substrate and the compression of the electrically-conductive member. This compressive clamping force may mechanically retain the cover to the substrate, and also compress the electrically-conductive member against at least one electrically-conductive surface disposed on the substrate, to establish electrical conductivity therebetween that is sufficient for EMI shielding performance.
