Abstract: A cutting jig cuts bonding material of a terminal joint between a magnetic head's slider and a flexure's wiring terminal. A base of the jig receives the slider. A blade moves along the base and faces a front side wall of the slider in a moving direction. An upright portion of the jig is formed on the base and has a stop face that faces a rear side wall of the slider in the moving direction. The blade moves toward the slider to come into contact with the bonding material, and is pressed to the front side wall of the slider. The bonding material is interposed in the moving direction while the rear side wall of the slider is brought into contact with and is stopped by the stop face when the slider is set on the base and the bonding material is cut.

Abstract: A method is provided for reclaiming a suspension from a disk drive head gimbal assembly (HGA). An ultrasonic probe is applied to the HGA's read/write head slider on a side opposite that of its solder balls. Ultrasonic oscillations are transmitted through the ceramic slider to the side with the solder balls. The oscillations break the brittle intermetallic compound of the slider balls and free the slider. The ultrasonic energy also weakens the epoxy adhesive between the slider and suspension. The method can be used with heat to further weaken the solder balls and adhesive.

Abstract: A method of reworking a head suspension removes a slider from the head suspension by pressing a blade from a first side toward a second side in a longitudinal direction of the slider to solder ball bonding, stopping the second side of the slider in the longitudinal direction with a holding mechanism, and forcing the blade to bite and cut the solder ball bonding to remove the slider from the flexure. The solder ball bonding is cut without applying extra force to components of the head suspension except the slider. The method improves product yield.

Abstract: Embodiments of the invention relate to techniques to remove a defective head gimbal assembly (HGA) from a head stack assembly and replace the defective HGA with a good one without allowing any good HGAs to be damaged. In one embodiment, a volatile alcohol solvent is moved by gravity from a holder included in a reworking tool provided for a reworking jig to a shearing edge of a cartridge type edge mounted in the holder. The alcohol solvent is thereby deposited on the shearing edge in a drop-like shape through surface tension. The cartridge type edge is, in this condition, made to slide on a surface of an actuator arm and is thereby inserted in a gap between contacting surfaces of a base plate of a mount plate and the actuator arm. This assigns the drop-like alcohol solvent a function as a lubricant. Possible vibration can therefore be prevented from being transmitted through a carriage to other HGAs.

Abstract: A disk drive that is the product of modifying a standard computer disk drive to read and write data in parallel with all of its transducer heads at once, rather than serially with only one head at a time. A method and apparatus are disclosed for protecting the disk drive's platters from damage and contamination while working on the interior of the disk drive case. The apparatus includes a hinged cover that replaces a conventional disk drive cover while work is being performed on circuitry within the disk drive case. The hinged cover seals off the platters and the inside of the disk drive case except for the circuitry being worked on.

Abstract: A method for head stack assembly (HSA) rework is disclosed. A first head gimbal assembly (HGA) includes a first suspension attached to an arm of the HSA, and a first flexure tail that terminates in a first bonding region that is bonded to a flexible printed circuit (FPC) of the HSA. The first HGA is removed by cutting the first bonding region from a remainder of the first flexure tail and detaching the first suspension from the arm. The first bonding region of the first flexure tail is left bonded to the FPC. A replacement HGA includes a replacement suspension and a replacement flexure tail that terminates in a second bonding region. The replacement HGA is installed on the HSA by attaching the replacement suspension to the arm, overlaying the second bonding region on the first bonding region, and bonding the second bonding region to the first bonding region.
