1. An interconnect assembly for providing electrical interconnection between a device to be tested and a testing system, the interconnect assembly comprising:

  • a carrier structure defining a plurality of openings therethrough; and

    a plurality of resilient electrical contact structures supported by the carrier structure, each of the plurality of resilient electrical contact structures comprising (a) a base portion planar with a surface of the carrier structure such that a first surface of the base portion is in contact with the surface of the carrier structure and a second surface of the base portion opposite the first surface is exposed, (b) a first resilient contact portion shaped to extend above the carrier structure such that the first contact portion is bent with respect to the base portion along a first bending axis, wherein the first contact portion further includes a first bow that is substantially coplanar with the first contact portion, and (c) a second resilient contact portion shaped to extend below the carrier structure such that the second contact portion is bent wit respect to the base portion along a second bending axis, wherein the second contact portion further includes a second bow that is substantially coplanar with the second contact portion, wherein one of the first contact portion or the second contact portion extends through a corresponding one of the plurality of openings defined by the carrier structure.
