Abstract: An apparatus includes a backplane having a ground plane. Conductor through holes extend through the backplane in rows and columns for conductors to project through the backplane in orthogonal arrays. Each row and column of the conductor through holes includes ground holes, each of which is sized to receive only a single ground conductor, with the single ground conductor in connection with the ground plane. Each row and column of the conductor through holes also includes signal holes, each of which is sized to receive only a single signal conductor, with the single signal conductor free of a connection with the ground plane. The backplane further has a plurality of nonconductor through holes at locations between and offset from the rows and columns of conductor through holes, with each of the plurality of nonconductor through holes having plating electrically connected to the ground plane.

Abstract: Electrical connectors capable of being mounted on circuit substrates by BGA techniques are disclosed. Also disclosed is a method for manufacturing such connectors. There is at least one recess on the exterior side of the connector elements. A conductive contact extends from adjacent the interior side of the into the recess on the exterior side of the housing. A controlled volume of solder paste is introduced into the recess. A fusible conductive element, in the form of solder balls is positioned in the recess. The connector is subjected to a reflow process to fuse the solder ball to the portion of the contact extending into said recess. Contacts are secured in the insulative housing of the connector by deformable sections that minimize stress imposed on the housing, thereby reducing warpage. Solder resist areas are formed on central portions of the contacts to promote uniformity of solder volume.

Abstract: A backplane has through holes for conductors to project through the backplane in arrays corresponding to respective circuit boards arranged along the front side of the backplane. The through holes include ground holes for receiving ground conductors in connection with a ground plane, and signal holes for receiving signal conductors free of connections with the ground plane. In accordance with a principal feature, the backplane is free of circuitry configured to interconnect signal conductors in the signal holes. This avoids problems associated with circuit density within the structure of a backplane. In accordance with another principal feature, each signal hole is wide enough to provide clearance for a respective signal conductor to extend fully through the signal hole free of contact with the backplane.

Abstract: An apparatus electrically interconnects pins that project from the rear side of a backplane in separate arrays corresponding to respective circuit boards at the front side of the backplane. The apparatus comprises a connector board assembly extending across the rear side of the backplane between separate arrays of pins. The connector board assembly has signal routing circuitry that electrically interconnects those separate arrays of pins. This enables the respective printed circuit boards to be electrically interconnected independently of any signal routing circuitry within the structure of the backplane. Accordingly, the apparatus preferably includes a backplane that is free of signal routing circuitry for interconnecting pins that extend through the backplane.
