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.
