摘要： A method for head stack assembly (HSA) rework is disclosed. A first head gimbal assembly (HGA) includes a first suspension attached to an arm of the HSA, and a first flexure tail that terminates in a first bonding region that is bonded to a flexible printed circuit (FPC) of the HSA. The first HGA is removed by cutting the first bonding region from a remainder of the first flexure tail and detaching the first suspension from the arm. The first bonding region of the first flexure tail is left bonded to the FPC. A replacement HGA includes a replacement suspension and a replacement flexure tail that terminates in a second bonding region. The replacement HGA is installed on the HSA by attaching the replacement suspension to the arm, overlaying the second bonding region on the first bonding region, and bonding the second bonding region to the first bonding region.

摘要： A head gimbal assembly for a disk drive includes a flexure tail terminal region having flexure bond pads in electrical communication with the head. Each of the flexure bond pads is aligned with one of a plurality of flexible printed circuit (FPC) bond pads. An anisotropic conductive film is disposed between the FPC and the flexure tail terminal region. The flexure tail terminal region overlaps the anisotropic conductive film in a bonding area. Each of the flexure bond pads is bonded to one of the plurality of FPC bond pads by the anisotropic conductive film in a bonding area. A conductive layer of the flexure tail terminal region includes an exposed conductive ground pad that is disposed outside of the bonding area, and/or disposed outside of an application area of a thermode tool that is pressed against the flexure tail terminal region during the bonding process.

摘要： A method of manufacturing a head suspension includes a punching process, a positioning process, and an affixing process. An objective part on the head suspension to which a damper 73 is affixed includes a discontinuous section 72. The punching process punches a damper material into the damper 73 whose shape corresponds to the shape of the objective part excluding the discontinuous section 72. The positioning process positions the damper 73 to the objective part so that the damper 73 avoids and surrounds the discontinuous section 72, and the affixing process affixes the damper 73 to the objective part. The method secures a uniform damping effect among manufactured head suspensions and improves the yield of dampers and head suspensions without deteriorating the functions and performances of the head suspensions.
