ABSTRACT:
A shielding panel for shielding circuit card slots on a computer chassis, and particularly a shielding panel for use with printed circuit board brackets and/or blank brackets to shield circuit card slots provides an arrangement for reducing the leakage of electromagnetic waves and/or radio frequency waves through a computer chassis by providing protrusions around circuit card slots in the slot frame. The design of the present shielding panel includes a tab which wraps around an edge of the circuit card slot to help place and hold the shielding panel in position while substantially eliminating the potential interference between neighboring panels and/or panels and neighboring slots and inhibits the formation of a gap between the shielding panel and the computer chassis slot frame, therefore, substantially eliminating the chance of a bracket tip catching in such a gap. The present shielding panel also provides protrusions which are bent such that they extend above the surface of the shielding panel but the ends of which extend below the surface of the shielding panel or at least close enough to the surface of the shielding panel to thereby substantially eliminate the chance of a bracket snagging on the protrusions.
