Abstract
A flexible circuit includes a plurality of electrical traces and a plurality of probe tips directly formed thereto. The electrical traces are made of a first electrically conductive material and the probe tips are made of a second electrically conductive material that is harder than the first electrically conductive material. The first material is copper or a copper alloy and the second material is nickel or a nickel alloy, where the second material may be plated with gold. Portions of the probe tips are exposed to facilitate electrical contact with contact pads of another electrical circuit. The flexible circuit may also include a ground layer to facilitate electrical correction with another electrical circuit at relatively high frequencies.
