Abstract
In one embodiment, a dummy via is created in a circuit board. The dummy via is positioned and coupled to a portion of a transmission line. This portion of the transmission line is further coupled to a signal lead of a connector, which creates additional capacitance to lower the impedance of the connector.
Claims15
A circuit board comprising:
- a footprint including a plurality of apertures, the footprint including an aperture to receive a signal lead of a connector and a neighboring aperture to receive a ground lead of the connector;
- and
- a dummy via formed in the circuit board between the aperture and the neighboring aperture, the dummy via being coupled to the signal lead of the connector when the plurality of leads of the connector are inserted through the footprint.
An electronic system comprising:
- a circuit board including a plurality of apertures associated with a component footprint, a dummy via and at least one transmission line coupled to the dummy;
- and
- a connector attached to the circuit board, the connector including a plurality of leads for insertion through the plurality of apertures, the plurality of leads include a ground lead and a signal lead that is inserted through a first aperture of the plurality of apertures and coupled to the at least one transmission line.
A method comprising:
- implementing a dummy via within a circuit board;
- and
- coupling the dummy via to a signal lead of a connector attached to the circuit board.
