Structural optimization of contact geometry for high performance connector

A connector includes a connector housing forming a receptacle configured to receive an add-in card. The connector further includes a first connector pin configured to electrically couple to the add-in card responsive to the add-in card being inserted into the receptacle. The first connector pin extends from the connector housing to contact a first solder pad disposed on a printed circuit board (PCB). The connector further includes a second connector pin configured to electrically couple to the add-in card responsive to the add-in card being inserted into the receptacle. The second connector pin extends from the connector housing to contact a second solder pad disposed on the PCB. The first connector pin is oriented toward the second connector pin to couple to the PCB in a toe-routing configuration and the second connector pin is oriented away from the first connector pin to couple to the PCB in the toe-routing configuration.
