A method and structure of an electrical connector is provided for tuning the impedance of the connector according to a given impedance of an electrical circuit in which the connector is interconnected. The connector includes a dielectric housing having a receptacle for receiving a complementary mating connector. A plurality of terminals are mounted on the housing. The terminals include body portions located in the housing and contact portions located at the receptacle for engaging appropriate terminals of the mating connector when inserted into the receptacle. The areas of the body portions of the terminals are selectively varied to vary the capacitance of the terminals and, therefore, the impedance of the connector to match the given impedance of the electrical circuit. When the connector is used for mounting to a printed circuit board, ground terminals have at least two feet for engaging a respective single ground trace of a common ground circuit on the printed circuit board for reducing the inductance between a particular ground terminal and its respective circuit trace.

A backplane signal connector assembly includes a header connector adapted for mounting on a backplane and a receptacle connector adapted for mounting on a daughter printed circuit board. Each connector includes a conductive housing having a cavity for receiving at least two signal terminals and at least one ground terminal. The signal terminal has an insert molded insulating mounting body about a portion thereof to provide a module for mounting in the cavity to insulate the terminal from the conductive housing. The ground terminal is in direct conductive engagement with the housing. The terminals are stamped and formed metal components. At least one ground clip is mounted on each conductive housing in direct conductive engagement therewith and is adapted for commoning to a ground on the respective backplane and daughter printed circuit board, whereby the housing establishes a primary ground reference for the connector.
