Abstract: A method of assembling a head gimbal assembly. The method comprises a series of steps which include: stacking a base plate, a load beam, and a flexure to form a three-layered stacked series with at least a bottom layer being a base plate series; joining portions of the load beam to the base plate, and the flexure to the load beam in the three-layered stacked series to make a suspension section; attaching a slider to the flexure in the suspension section to make a head gimbal assembly; load-bending a hinge portion formed in the head gimbal assembly; and heating the hinge portion in order to adjust a bending load on the hinge portion at a predetermined bending angle to a predetermined value.

Abstract: A capillary tube for a solder ball connection device connects a first connection surface of a pad to a second connection surface of a pad with a solder ball. The first connection surface is formed at a slider held by a slider holder in a disk unit. The second connection surface is formed at an end of a lead wired to the slider holder. The capillary tube has a ball regulator with a substantially conic, hollow portion. The solder ball regulator has an opening at its top that opens to the tip of the hollow portion. The center axes of the hollow portion and the opening are common. The solder ball regulator also has a pair of projections along the center axis around the opening, where the projections face each other with the center axis therebetween. The projections regulate the movement of the solder ball. The tip of the hollow portion is tapered when viewed from a line connecting the pair of projections and the extreme tips of the tapered tip portions.
