Abstract
A head suspension assembly for a disk drive includes a load beam and a laminated flexure that comprises a stainless steel layer, a copper trace layer, and a dielectric layer between the stainless steel layer and the copper trace layer. The laminated flexure includes a flexure tail that extends away from the load beam to a flexure tail terminal region. The copper trace layer includes a plurality of flexure bond pads in the flexure tail terminal region. The stainless steel layer includes a plurality of backing islands in the flexure tail terminal region. Each of the plurality of backing islands is aligned with a corresponding one of the plurality of flexure bond pads. A noble metal layer is disposed on the plurality of backing islands.
