Abstract
A method is provided for reclaiming a suspension from a disk drive head gimbal assembly (HGA). An ultrasonic probe is applied to the HGA's read/write head slider on a side opposite that of its solder balls. Ultrasonic oscillations are transmitted through the ceramic slider to the side with the solder balls. The oscillations break the brittle intermetallic compound of the slider balls and free the slider. The ultrasonic energy also weakens the epoxy adhesive between the slider and suspension. The method can be used with heat to further weaken the solder balls and adhesive.
