Surface mount connector pad
View Patent ↗A circuit board includes first and second lines of surface mount pads, and a trace. The surface mount pads within the first line extend from a first edge of the circuit board toward a second edge of the circuit board. The surface mount pads within the second line extend from the first edge of the circuit board toward the second edge of the circuit board, and the surface mount pads within the second line are further from a third edge of the circuit board as compared to the surface mount pads within the first line. The trace is located on a top surface of the circuit board, and extends from the third edge to a fourth edge of the circuit board. The spacing between first adjacent surface mount pads within the first line enables the trace to be routed between the first adjacent surface mount pads with less crosstalk between signals on the trace and signals on the surface mount pads within the first line.
