Abstract:
A probe for making electrical connection to contact pads on microelectronic devices, said probe comprising:(a) a conductive main body forming a torsional spring along a long axis and having a first and a second end; (b) a rigid substrate with a surface; (c) a single rigid electrically conductive post supporting said first end of said main body away from said surface of said substrate; (d) an arm extending distally from said second end of said main body atone an axis offset laterally from the lone axis of the main body and generally parallel to the substrate; (e) support means, said support moans being near said second end and disposed at said surface of said substrate, said support means providing a pivot point for said arm relative to said main body; and (f) an electrically conductive tip structure with a base disposed on said arm, wherein a displacement of said tip structure toward said substrate causes twisting of a substantially straight elongate portion or said main body as torsional distortion about the long axis.
