1. A socket assembly comprising:
an electrical interconnect having an insulator having an upper surface and a lower surface, the insulator including apertures therethrough, the electrical interconnect including primary contacts received in corresponding apertures and secondary contacts received in corresponding apertures, the primary contacts including primary conductive polymer columns having upper contact tips extending above the upper surface to distal ends and lower contact tips extending below the lower surface to distal ends, the upper and lower contact tips for electrically interconnecting first and second electronic packages, respectively, the secondary contacts including secondary conductive polymer columns having upper contact tips extending above the upper surface to distal ends and lower contact tips extending below the lower surface to distal ends, the upper and lower contact tips for electrically interconnecting the first and second electronic packages, respectively;
wherein the upper contact tips above the upper surface of the primary conductive polymer columns have a first shape and the upper contact tips above the upper surface of the secondary conductive polymer columns have a second shape different from the first shape to provide shielding in spaces between the upper contact tips of the primary conductive polymer columns; and
wherein the lower contact tips below the lower surface of the primary conductive polymer columns have a third shape and the lower contact tips below the lower surface of the secondary conductive polymer columns have a fourth shape different from the third shape to provide shielding in spaces between the lower contact tips of the primary conductive polymer columns.
