Abstract
A method to manufacture a head stack assembly for a disk drive, the method comprising: attaching a head gimbal assembly that includes a flexure tail having flexure bond pads to an actuator that includes a flexible printed circuit (FPC) with FPC bond pads; folding each of the flexure bond pads upon itself such that the flexure tail is substantially thicker at each of the folded flexure bond pads; aligning the flexure bond pads with the FPC bond pads; introducing an adhesive material that includes electrically conductive beads of substantially similar size between each of the flexure bond pads and corresponding ones of the FPC bond pads; and bringing a thermode tool into contact with the flexure bond pads after folding, with the thermode tool pressing the flexure bond pads against the FPC bond pads for a period.
