A first connector includes a first plurality of eye-of-needle (EON) pins. Each EON pin of the first plurality includes two opposing spring arms. Each EON pin of the first plurality is configured to be received within a corresponding electrical via of a printed circuit board (PCB) such that the spring arms engage walls of the corresponding electrical via at a set of contact points. A second connector includes a second plurality of EON pins. Each EON pin of the second plurality includes two opposing spring arms. Each EON pin of the second plurality is configured to be received within a same corresponding electrical via of the PCB as a corresponding EON pin of the first plurality located at a same relative connector body location such that the spring arms engage the walls of the same corresponding electrical via at a different set of contact points.
