Electrical contacts to motors in dual stage actuated suspensions

摘要

Various embodiments concern a dual stage actuation flexure having a motor contact paddle for connecting to a terminal of a piezoelectric motor. The flexure comprises a paddle having a top side and a bottom side, the paddle comprising at least one void, each void extending through the paddle from the bottom side to the top side. The paddle further comprises a stainless steel base, a conductor comprising a layer of metal, and a dielectric layer having a first section and a second section, the first section positioned between the conductor and the stainless steel base to overlap the stainless steel base and the second section extending beyond the stainless steel base to not overlap the stainless steel base. The bottom side of the paddle is configured to connect to the terminal with electrically conductive adhesive.
