Abstract:
1. An assembly comprising: a substrate including first and second contact pads; an elongated coaxial spring finger having an anchor portion attached to the substrate, a curved cantilever portion extending from the anchor portion away from the substrate, and at least one tip located at a distal end of the cantilever portion, wherein said coaxial spring finger includes: a first elongated conductive layer having a first end connected to the first contact pad and a second end located adjacent to the at least one tip, wherein the first elongated conductive layer includes a first finger portion defining a first tip and a second finger portion defining a second tip; a dielectric layer including a first dielectric portion extending along the first finger portion to the first tip; and a second elongated conductive layer having a first end connected to the second contact pad and a second end located adjacent to the at least one tip, wherein the second elongated conductive layer is disposed on the dielectric layer over the first finger portion such that the first finger portion and the second conductive layer are separated by the first dielectric portion.
