Abstract
An EMI seal or gasket blocks electromagnetic radiation between electrically conductive bodies and encompasses an area using a number of adjacent segments, each generally formed as an elongated seal with a resilient core. An electrically conductive surface bears against the conductive bodies and extends at least partway around the respective segment. The segments are attached to one another along lengthwise seams, preferably using conductive tape on one of the opposite sides of the seal. The conductive surface is preferably provided by a metallized fabric affixed to a resilient foamed polymer core, which can be molded in the fabric or otherwise formed or cut and attached, e.g., adhesively. The conductive fabric or other surface material extending substantially around the segments provides more conducting paths across the gap between the conductive bodies than a non-segmented seal of comparable size, thereby improving shielding efficiency. The seal can be die cut, including cutting through the width of one or more segments, and remains intact, providing many of the benefits of both wide seals or gaskets and elongated narrow seals.
