Abstract: PROBLEM TO BE SOLVED: To provide the method for soldering a suspension and a lead of a converter of a miniaturized disk drive. SOLUTION: The suspension member 32 is provided with the integrated electrically conductive lead 120 extending to the rear tail part along the longitudinal direction. This lead 120 is extended beyond the tail part and electrically connected with an acceptor pad member. The distant end 135 of the lead is provided with a recessed area at the edge of a terminal for guiding the flow of the fluid solder to the joint part. This recessed area is formed into e.g. a chamfer 136, preferably to be semicircular. The tail pad is provided with a pair of tab members 134 accepted by an opening part of the acceptor pad member, for accurately aligning the lead.

Abstract: PROBLEM TO BE SOLVED: To protect an MR head having an MR sensor against the damage generated by the presence of an electric field having static electricity by discharge. SOLUTION: The MR head is provided with shunts in the positions immediate near the terminals of adjacent conductive leads 18, 19 heading toward the MR sensor on the MR head across these leads. Solder overhanging parts of at least one of selected shapes are arranged adjacently to the leads in order to facilitate the removal of the shunts by causing the reflow of solder. These overhanging parts include limitation overhanging parts 30, 32 which play the role of limiting the solder within the shunt regions when the shunts are formed and an assignment part 32 which acts to transfer the solder from the shunt regions to an assigned position at the time of the next reflow of the solder and to give rise to physical breakdown in the shunt accordingly. The need for the physical removal of the solder material is eliminated.

Abstract: PROBLEM TO BE SOLVED: To control strictly spacing between a slider and a suspension. SOLUTION: A slider/suspension assembly is constituted so as to provide a spacer device separating the slider 56 from the suspension 42 as for a data recording disk file. In such a case, this spacer device contains one or above of solder bumps 66, and their heights are controlled strictly, and the required spacing is given. This spacing device prevents the contact between the slider 56 and the suspension 42.

Abstract: A method for the fabrication of a data recording disk file slider-suspension assembly, the slider being of the type having an air bearing surface, a back side opposite the air bearing surface and a trailing edge having a read or write transducer formed as a thin film thereon with electrical leads formed solely on the trailing edge and terminating adjacent the slider back side at termination pads, and a suspension having etched conductive lead structures and conductive contact pads connected to the lead structures. The method comprising the steps of forming a solder bump on each of the termination pads and each of the contact pads, wherein one or more solder bumps are selectively flattened, mechanically attaching the back side of the slider to the suspension such that the termination pads are properly aligned with the contact pads, and heating the solder bumps so as to reflow the termination pad and contact pad bumps such that they electrically connect, wherein a selectively flattened bump extends along an axis defined by a point on one pad and a point on another pad when heated to make contact with another bump.

Abstract: Disc file data read/write head assembly has a slider (56) having an air bearing surface facing the data surface of the disc and a back surface which is attached to a suspension (42) which biases the slider in close proximity to the disc surface, in which the spacing between the slider (56) and suspension (42) is maintained by at least one solder bump (66). Also claimed is the method of controlling the spacing between the suspension and slider as described above and in which the slider is attached to the suspension by adhesive surrounding the solder bumps, and such a slider suspension arrangement in a magnetic disc data storage system.

Abstract: MR heads having MR sensors are protected against damage caused by electrostatic discharge or the presence of electrostatically charged fields. A shunt is provided across the adjacent conductive leads or traces to the MR sensor at a point that is immediately adjacent their termination on the MR head. A solder bridge may be used for the shunt. The solder shunt is removed prior to putting the integrated suspension on which the MR head is mounted into operation in a magnetic disk drive system. The solder shunt is removed by reflowing the solder and drawing the reflowed solder away from the leads to break electrical connection of the shunt across the adjacent leads to the MR sensor. To facilitate removing the shunt by reflowing the solder, at least one solder lobe of a chosen geometry is placed adjacent a lead. This lobe includes a confining lobe which serves to confine the solder in the shunt region when the shunt is formed, and a designated portion which serves to draw the solder to a designated location away from the shunt region upon subsequent solder reflow, thereby causing a physical break in the shunt. Physical removal of the solder material would not be required. The shunt may also be in the form of an integral bridge of conductive material interconnecting the adjacent leads, which is removed by using a laser to melt the material.

Abstract: A suspension system for supporting a magnetic read/write slider comprises a load beam, a slider support member and a flexure comprised of a first flexure arm and a second flexure arm. The electrical conductors to the slider are positioned either along one or both flexure arms or adjacent to, but outside of, the second flexure arm, so as not to contribute to the stiffness of the second flexure arm. The electrical conductors are comprised of a laminated material which includes a conductor layer, such as a high strength copper alloy, a dielectric layer and a support layer. A first plurality of slots extend completely through the first flexible finger region, and a second plurality of slots extend completely through the second flexible finger region for providing regions into which the electrical conductors can move when the flexure undergoes deflections (see fig 12).
