Abstract
An electromagnetic interference (EMI) shield is provided. The EMI shield may include a frame and a cover operative to be placed over the frame. The cover may include snaps or tabs extending from the surface of the cover and operative to engage side walls of the frame. At least one edge of the cover, for example an edge operative to be placed near an electronic device housing, may not include snaps or tabs to reduce the size of the EMI shield near the housing. Instead, the frame may include one or more stepped returns, the top-most of which may be operative to be placed in contact with the cover. The cover may include a spring, an emboss and one or more grounding points to ensure that the cover remains in contact with the frame despite the absence of snaps or tabs securing the cover to the frame.
