Abstract
A head gimbal assembly for a disk drive includes a read head and a suspension assembly. The suspension assembly includes a load beam and a laminate flexure. The laminate flexure includes a structural layer, a dielectric layer, and a conductive layer that includes a plurality of electrical traces. The laminate flexure includes a tongue portion that connects to the read head and a flexure tail that extends away from the tongue portion. The flexure tail includes a plurality of flexure bond pads. Each of the plurality of flexure bond pads includes a widened region of a corresponding one of the plurality of electrical traces in the conductive layer, and a corresponding one of a plurality of segments or discontinuous islands in the structural layer.
