ABSTRACT:
Embodiments of the present invention provide a head gimbal assembly manufacturing method which can attach another magnetic head slider to a suspension to be reused without addition of solder. According to one embodiment of the present invention, a head gimbal assembly (HGA) is attached to a jig. Both sides of a portion close to the rear end of a magnetic head slider are gripped with hot tweezers heated at about 200° C. They are heated for about four seconds while applying force in a direction of peeling off the magnetic head slider from gimbals, thus removing the magnetic head slider from the gimbals. When another magnetic head slider is attached to the suspension, an adhesive adhered to the gimbals is removed and another adhesive is applied to the gimbals. The back of another magnetic head slider is pressed to the adhesive, whereby the magnetic head slider is fixed to the gimbals. Next, the solder fillet left on the gimbals is irradiated with laser beams to be melted and joined to an electric terminal.
