A connector assembly is disclosed to reduce discontinuity impedance between golden finger connectors and components on a circuit board. The assembly includes a circuit board including a connector edge. A plurality of connectors is formed on the connector edge on a first surface of the circuit board. A ground plane is formed on part of the circuit board on a second opposite surface of the first surface. The ground plane leaves the second opposite surface under the connector edge exposed. A ground loop is formed on the second opposite surface under at least two of the plurality of connectors.
