Abstract
An EMI gasket (20) includes a plurality of serrations (34) along at least one edge (35, 36). The serrations (34) are arranged side-by-side so that each may be articulated individually. That is, one of the serrations (34) may be displaced significantly out of the plane of the gasket without affecting adjacent serrations. Thus, when the edge of the gasket (20) is compressed between two surfaces which include a discontinuity (40) such as a step or protuberance between them, the serration in contact with the discontinuity is displaced out of the plane of the gasket without displacing adjacent portions of the gasket. Allowing a portion of an EMI gasket (20) to be displaced out of the plane of the gasket without affecting adjacent portions of the gasket substantially reduces or eliminates gaps which occur due to the failure of the gasket to precisely follow the contour of a component.
