    Abstract: An EMI shield for use on a printed wiring board (PWB) of a circuit pack includes an open-ended box-like structure having a laterally extending flange completely encircling the opening into the box-like structure. The box is of an EMI impervious material, preferably stainless steel. An electrically conductive O-ring gasket is disposed in a groove in the flange. Both the groove and the flange completely encircle the box opening. The shield is secured to a PWB by pegs secured to the flange at positions radially outwardly of the gasket and extending entirely through openings through the PWB. Preferred pegs comprises pairs of side-by-side prongs integral with the shield flange but extending downwardly therefrom. Each prong terminates in an oppositely directed, return-bent detent with the detent pairs functioning as a spring-biased latch for removably mounting the shield to the PWB.
