Abstract
Abstract A ground plane interconnection system using multiple connector contacts interconnects ground planes between backplanes, between circuit boards or between backplanes and circuit boards. When a column or a portion of the column of contacts is allocated to the ground plane interconnect, the ground plane interconnects within the acceptable operational impedance range. These contacts behave as a plane in the direction of interest in a backplane system.
