Disk drive suspension assembly having a flexure bond pad shelf separate from a tongue
Abstract:
A disk drive includes a suspension assembly that includes a load beam and a laminated flexure. The laminated flexure includes a structural layer, a dielectric layer, and an electrically conductive layer. The electrically conductive layer includes a plurality of flexure bond pads. The structural layer includes a tongue and a flexure bond pad shelf. The flexure bond pad shelf underlies each of the plurality of flexure bond pads. The flexure bond pad shelf is separate from the tongue in the structural layer so that the structural layer nowhere connects the flexure bond pad shelf to the tongue. A fine actuator may be disposed on and bonded to the tongue to produce relative motion between the head and the tongue. With the flexure bond pads bonded to the plurality of head bond pads, the fine actuator may also produce relative motion between the flexure bond pad shelf and the tongue.
