Abstract
Abstract A multi-row box connector having continuous ground planes formed as part of the connector housing for electrically interconnecting printed circuit boards. The multi-row box connector includes first and second insulative housing members each having thin metallic films deposited on the internal and external sidewalls thereof, respectively, to form the continuous ground planes. The thin metallic films may be deposited on respective housing members by sputtering. The ground planes provide early ground mate as well as EMF shielding and minimization of cross talk between the signal elements of the box connector.
