    摘要: A suspension assembly is designed to carry a slider and read/write head elements in a magnetic data storage device. The suspension assembly is formed from a composite laminate structure that includes first, second, third, fourth and fifth material layers. The layers are arranged such that the second layer is disposed between the first and third layers, and the fourth layer is disposed between the third and fifth layers. The laminate structure is configured using a suitable removal process, such as partial chemical etching, to define a mount plate, a hinge, a load beam functional end, and an electrical lead system. The laminate structure may be further formed with a flexure gimbal system that comprises the third, fourth and fifth layers.

    摘要: 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.

    摘要: A flexure for use in a head gimbal assembly comprising a single narrow torsion beam that connects a suspension load beam to a slider support member. The flexure is centered underneath a read/write slider and may be comprised of a laminated material having a conductor layer, a dielectric layer and a support layer. A plurality of electrical leads may be formed in the conductor layer for attachment the slider. The slider is mechanically attached to the slider support member by a first set of solder balls the height of which create a space for accommodating deflections of the flexure and allowing the electrical leads to pass underneath the slider. Electrical connections to the slider are made using a plurality of right angle fillet joints between the slider and a second set of solder balls on the slider support member. The shape of the torsion beam may be varied to yield different levels of stiffness to pitch, roll and yaw movement of the flexure.

    摘要: In a data disk file a slider is mechanically attached to the suspension by means of reflowed solder balls. A pattern of solder contact pads is formed on the back side of the slider and a similar pattern of solder-wettable regions is formed on the suspension. Solder balls are formed on either the solder contact pads or the solder-wettable regions, the slider is located on the suspension so that the solder balls are in registration between the solder contact pads and solder-wettable regions, and the solder is heated to reflow, thereby forming solder joints as a mechanical connection between the slider and suspension. When a thin film transducer is formed on the slider trailing edge and the suspension is a laminated type with patterned conductors, solder balls are also formed on the transducer lead terminations on the trailing edge and on a row of solder-wettable regions on the suspension near the location where the trailing edge of the slider is to be located. In this embodiment, when the slider with thin film transducer, with solder balls on the lead terminations, is located over the suspension then all of the solder balls are heated. The solder balls for providing mechanical connection collapse during reflow, thereby causing the solder balls on the transducer lead terminations to come in contact with and flow together with the solder balls formed on the row of solder-wettable regions on the suspension. Thus the mechanical attachment of the slider is made simultaneously with the electrical connection of the transducer lead to the disk file read/write electronics.
