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.

摘要： Various embodiments concern a suspension having a DSA structure on a gimbaled flexure comprising a loadbeam having a load point dimple and a flexure attached to the loadbeam. The flexure comprising a metal layer having a pair of spring arms, a tongue located between the spring arms, and a pair of struts. The struts connect the pair of spring arms to the tongue. One of the struts is located distal of the other strut. The pair of struts has a midline centered between the pair of struts. The suspension further comprises a motor mounted on the flexure. Electrical activation of the motor bends the pair of struts to rotate the tongue about an axis of rotation. The axis of rotation is aligned with the dimple. The midline is offset distally or proximally with respect to the axis of rotation. The offset counters a mass in imbalance of the tongue.
