Abstract
This invention relates to personal computers, and more particularly to the provision of a shielding structure for attenuating the possible effects of electromagnetic interference on input/output circuits of the computer while structurally reinforcing a side edge portion of a multilayer planar board. The shielding structure has two cooperating constituent parts, one being particularly formed ground plane areas in exterior layers of the planar board and the other being a particularly formed thin sheet metal member which extends about and substantially encloses connectors by which input/output signals are passed to circuits within the planar board.
