Abstract:
A method of wiring a head suspension assembly, comprising the steps of:preparing a suspension assembly comprising a suspension for elastically supporting a slider on which a magnetic head of a disk storage device is provided, and a tab frame formed integrally with the suspension so that the tab frame and a peripheral suspension on a top side of the suspension are substantially coplanar, the tab frame having bonding portions to which a plurality of wires are each bonded for electrically connecting the magnetic head and a controller which transmits data relative to the magnetic head, the tab frame having a first frame integrally connected to the suspension and being bendable substantially perpendicular to the suspension, and a second frame including the bonding portions, integrally connected to the first frame, and being bendable substantially perpendicular to the first frame; a first fixing step for fixing a tube binding the plurality of wires on a predetermined location on the suspension assembly; a second fixing step for fixing the plurality of wires extending from the fixed tube on a predetermined location on the suspension, while leading them to a top side of the suspension, to which the slider on which the magnetic head is provided is attached; a third fixing step for bonding each wire led to the top side of the suspension to the bonding portions of the second frame of the tab frame; an insulation film removing step for removing the insulation film of each connecting portion of the plurality of wires to connect the plurality of wires to respective connecting pads of the slider; a first frame bending step for bending the first frame substantially perpendicular to the suspension; a second frame bending step for bending the second frame substantially perpendicular to the first frame, thereby to position the connecting portion of the plurality of wires bonded to the bonding portions of the second frame at the respective connecting pads on the slider; and an ultrasonic welding step for ultrasonically welding the plurality of wires to the respective connecting pads on the slider.
