Abstract: Devices including high-aspect ratio electroplated structures and methods of forming high-aspect ratio electroplated structures are described. A method for manufacturing metal structures includes providing a substrate having a metal base characterized by a height to width aspect ratio A/B and electroplating a metal crown on the base to form the metal structure with a height to width aspect ratio A/S greater than the aspect ratio A/B of the base.

Abstract: A system and methods for manufacturing devices such as flexures using process coupons are described. The method includes performing a test on at least one feature of a coupon, the coupon is included on an assembly sheet used in manufacturing flexures. The at least one feature is produced by a manufacturing processing step that is used to produce a portion of a flexure. And, the physical characteristics of the feature include at least one physical characteristic that is different than physical characteristics of the portion. The method also including determining the manufacturing processing step will produce an abnormal portion of a flexure based on the performed test. Further, the method includes adjusting the manufacturing processing step and manufacturing a portion of a flexure using the adjusted manufacturing processing step.

Abstract: 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.

Abstract: A method of manufacturing an integrated lead head suspension flexure of the type having conductors on a spring metal layer capable of being etched by a first etching process. The method includes forming a patterned layer having gaps one or more flying lead regions of dielectric material on a major surface of the spring metal layer and forming one or more conductive leads on the flexure, including onto the dielectric material and over exposed spring metal at the gap at each flying lead region. At least the flying lead portion of the conductive lead is formed from conductive material resistant to the first etching process. The method also includes etching a flying lead region of the spring metal layer to remove a portion of the spring metal layer in the flying lead region and expose the flying lead portions of the conductive lead.
