A socket (130) employs a substrate (310) including a conductive network. An array of first contacts (136) is on a top surface of the substrate (310) and arranged to engage an integrated circuit (110). An array of second contacts (138) is on a bottom surface of the substrate (310) and arranged to engage a circuit board (120). The conductive network electrically connects the first contacts (136) respectively to the second contacts (138), and the first contacts (136) include a routed first contact (136′) that the conductive network routes horizontally in or on the substrate (310).
