  • Method for bonding slider and suspension together and deciding conditions of laser beam irradiation
    Patent number: 6676778
    Abstract: A slider and suspension of a hard disk drive are joined with a low modulus epoxy adhesive. The slider and suspension are set in a bonding jig while they are moving from process to process or subjected to a thermosetting treatment in a controlled temperature chamber. The slider and suspension must be kept bound together with the bonding jig until the adhesive is cured through a thermal treatment. The low modulus epoxy adhesive is cured with heat from a laser beam. In addition, a resistance value of the head disposed at the slider is measured so as to monitor the temperature of the head, thereby deciding both output and irradiation time of the laser beam for obtaining a desired strength of the bond within a predetermined temperature range.

  • Apparatus and method for adhesively connecting wires to a suspension arm in a disk drive assembly
    Patent number: 6112400
    Abstract: A head suspension assembly including a load beam having predefined gluing regions for gluing a bundle of wires thereto. For each gluing region, the load beam is partially-etched with the pattern that includes a plurality of grooves. Preferably, the pattern within the gluing region includes a set of parallel grooves. The gluing regions can be formed at very little cost because partial etching can be performed simultaneously etching other features on the load beam. Advantageously, the gluing regions provide enhanced adhesion between the wires and the load beam which reduces the possibility of failure during manufacture, thereby reducing costs.
