Abstract
A method of surely removing a read/write slider from a flexure without large displacement of the slider, the slider attached to the flexure of the head suspension through an adhesive, comprises heating the slider so that the adhesive is heated through an adhered surface of the slider being in contact with the adhesive; and applying ultrasonic vibration to the slider so that the adhered surface of the slider vibrates at ultrasonic frequency with respect to the adhesive.
Claims4
A method of removing a read/write slider from a flexure of a head suspension, the slider attached to the flexure of the head suspension through an adhesive, comprising:
- heating the slider so that the adhesive is heated through an adhered surface of the slider being in contact with the adhesive,
- applying ultrasonic vibration to the slider so that the adhered surface of the slider vibrates at a first ultrasonic frequency with respect to the heated adhesive to cause a shearing force due to the ultrasonic vibration on an interface between the heated adhesive and the adhered surface, thereby to detach the slider from the heated adhesive;
- and
- removing the detached slider from the flexure;
- and
- wherein said heating comprises bringing a heating jig into contact with the slider;
- and wherein said applying comprises vibrating the heating jig at a second ultrasonic frequency.
A method of removing a read/write slider from a flexure of a head suspension, the slider attached to the flexure of the head suspension through an adhesive, comprising:
- heating the slider so that the adhesive is heated through an adhered surface of the slider being in contact with the adhesive;
- applying ultrasonic vibration to the slider so that the adhered surface of the slider vibrates at a first ultrasonic frequency with respect to the heated adhesive to cause a shearing force due to the ultrasonic vibration on an interface between the heated adhesive and the adhered surface, thereby to detach the slider from the heated adhesive;
- and
- removing the detached slider from the flexure;
- wherein the heating and applying are performed concurrently;
- wherein said heating comprises bringing a heating jig into contact with the slider;
- and
- wherein said applying comprises vibrating the heating jig at a second ultrasonic frequency.
A method of detaching a read/write slider from a flexure of a head suspension, in which the slider is attached to the flexure of the head suspension through an adhesive before said detaching, comprising:
- heating the slider so that the adhesive is heated through an adhered surface of the slider, the adhered surface being in contact with the adhesive;
- applying ultrasonic vibration to the slider so that the adhered surface of the slider vibrates at a first ultrasonic frequency with respect to the heated adhesive;
- and
- vibrating the adhered surface at the first ultrasonic frequency so that a shearing force action of said vibrating acts at an interface between the heated adhesive and the adhered surface to accomplish said detaching of the slider from the heated adhesive, and
- wherein said detaching accomplished by said vibrating of the adhered surface is a complete detachment of said slider from said heated adhesive.
