Abstract
An EMI shielded apparatus having a substrate with at least one electrical component disposed on it; a plurality of discrete electrically conductive fastening units disposed in a pattern on the substrate surrounding the at least one electrical component; a shield comprising a dielectric material layer having an inner surface and an outer surface and an electrically conductive layer over at least one of the inner and outer surface; a plurality of apertures formed in the shield such that the apertures correspond to the pattern of the electrically conductive fastening units; wherein at least one of the apertures has a contact region and wherein both the dielectric material layer and the electrically conductive layer of the shield at the contact region of the aperture are deflectable to the extent necessary to allow the contact region to engage and retain the electrically conductive fastening unit; and wherein the electrically conductive layer of the shield at the contact region is in electrical contact with the electrically conductive fastening unit.
