| 1. An interconnection element comprising:
a post coupled at a first end to a surface of a substrate, the post extending away from the substrate to a second end of the
post;
a beam structure comprising:
a body coupled to the second end of the post, and
a plurality of leaf portions extending from the body to distal ends of the leaf portions, each of the leaf portions being
generally parallel to the surface of the substrate, there being a space between all adjacent leaf portions from the body to
the distal ends of the adjacent leaf portions such that the distal ends of the adjacent leaf portions are separated by the
space; and
a contact tip coupled to a free end of the beam structure opposite the body of the beam structure.
