A connector system including a circuit card and method of manufacturing same is provided. By way of example, the system includes a connector having an elongated housing with an elongated card-receiving slot. A plurality of signal terminals and ground terminals are mounted on the housing along the slot and have contact sections extending into the slot. A circuit card has an edge insertable into the slot, a ground plane facing a surface of the card at least near the edge and a plurality of signal contact pads and a plurality of ground contact pads along the edge for engaging the contact sections of the signal terminals and the ground terminals, respectively. The size or area of the signal contact pads is varied relative to the ground contact pads to vary the capacitance in the area of the terminal-to-circuit card interface and, thereby, vary the impedance of the system.
