Abstract: The invention provides tester load board shields for attachment to tester load boards. The shields of the invention protect from physical damage and electromagnetic interference. A preferred embodiment of a tester load board shield of the invention is disclosed in which a disc and outer rim of conductive metal such as aluminum or aluminum alloy are configured to accept a tester load board. The tester load board shield has holes to align with a selected tester load board for attachment of the shield thereto. Stanchions are provided to facilitate attachment of the Loadboard with shield to automatic test equipment known in the arts while a tester load board, also familiar in the arts, is fastened to the shield. Another embodiment of a tester load board shield is disclosed in the shape of annulus configured to contain a tester load board within an outer rim planar surface and inner rim.
