Abstract

An apparatus for detaching a head slider bonded onto a mounting plate of a suspension includes a platform on which a head gimbal assembly is mounted; a heating device for heating a joint section between the head slider and the suspension to decrease the bonding force; a latching part for latching the mounting plate at a position on a center line of the mounting plate in the lengthwise direction and/or at positions symmetric about the center line; and a clamp device for moving the head slider in a direction along the center line with the heating to detach the head slider from the mounting plate.

Claims (29)

1. An apparatus for detaching a head slider bonded onto a mounting plate of a suspension comprising:

a platform on which a head gimbal assembly is mounted;

a heating device for heating, a joint section between the head slider and the suspension to decrease the bonding force;

a latching part for latching the mounting plate at a position on a center line of the mounting plate in the lengthwise direction and/or at positions symmetric about the center line;

and a clamp device for moving the head slider in a direction along the center line with the heating to detach the head slider from the mounting plate,

the latching part has a pin inserted into a through-hole formed on an opposite side of the mounting plate from an end surface of the slider to latch the mounting plate,

wherein the clamp device is adapted for moving the head slider in a direction toward the pin to detach the head slider from the mounting plate.

2. The apparatus according to claim 1 , wherein

the head slider moves in the direction along the center line by virtue of the decreased bonding force at the joint section by the heating; and

the clamp device moves the head slider further in the direction along the center line to detach the head slider from the mounting plate after the heating.

3. The apparatus according to claim 1 , wherein the clamp device starts to move the head slider along the center line with the latching part latching the mounting plate.

4. An apparatus for detaching a head slider bonded onto a mounting plate of a suspension comprising:

a platform on which a head gimbal assembly is mounted;

a heating device for heating a joint section between the head slider and the suspension to decrease the bonding force;

a latching part for latching the mounting plate at a position on a center line of the mounting plate in the lengthwise direction and/or at positions symmetric about the center line;

and a clamp device for moving the head slider in a direction along the center line with the heating to detach the head slider from the mounting plate,

wherein the head slider has an end surface on which connection terminals for signals are provided;

the latching part has a pin inserted into a through-hole formed on an opposite side of the mounting plate from the end surface to latch the mounting plate;

the clamp device moves the head slider in a direction toward the pin to detach the head slider from the mounting plate; and

the head slider is detached from the mounting plate without touching the pin by virtue of the distance between the pin and the opposite surface from the end surface.

5. The apparatus according to claim 4 , wherein the latching part latches the mounting plate only by the pin inserted into the through-hole formed on the center line of the mounting plate.

6. The apparatus according to claim 4 , wherein

an outer circumferential surface of the pin is a tapered surface; and

the clamp device starts to move the head slider with the outer circumferential surface touching an inner circumference of the through-hole.

7. The apparatus according to claim 4 , wherein

the head slider moves in the direction along the center line by virtue of the decreased bonding force at the joint section by the heating; and

the clamp device moves the head slider further in the direction along the center line to detach the head slider from the mounting plate after the heating.

8. The apparatus according to claim 4 , wherein

the clamp device starts to move the head slider along the center line with the latching part latching the mounting plate.
