Abstract
A head gimbal assembly for a disk drive includes a read head, 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 and includes a plurality of flexure bond pads that may facilitate ultrasonic or ACF bonding. Each of the plurality of flexure bond pads consists of a widened region of a corresponding one of the plurality of electrical traces in the conductive layer, and a gold coating upon the widened region. The widened region of each of the plurality of electrical traces extends transverse to the flexure tail's longitudinal axis at least 2.5 times more than it extends parallel to the flexure tail's longitudinal axis.
