Abstract:
A head-gimbal assembly (HGA) with a suspension-lead pad having a form that is configured to inhibit formation of an inter-pad solder bridge. The HGA includes a gimbal, a head-slider and a plurality of suspension-lead pads. The head-slider is coupled with the gimbal, and includes a plurality of head-slider pads. The plurality of suspension-lead pads is coupled with the plurality of head-slider pads by a plurality of solder bonds. A suspension-lead pad comprises a first lateral side, a second lateral side, a proximal side, disposed in proximity to a respective head-slider pad, and a distal side. A first width of the suspension-lead pad closer to the proximal side is substantially larger than a second width of the suspension-lead pad further from the proximal side than the first width. A disk drive including the HGA, and a head-slider with a head-slider pad having similar form to the suspension-lead pad are also provided.
