Abstract
A magnetic head slider with at least one thin-film magnetic head element on a suspension is mounted. This mounting includes electrically connecting the magnetic head slider with the suspension with ball bonding connections. Electrical property of the thin-film magnetic head element is inspected, and then the ball bonding connections are separated when it is judged that the thin-film magnetic head element has defective electrical property. Then, the magnetic head slider is detached from the suspension, and thereafter a new magnetic head slider with at least one thin-film magnetic head element is mounted on the suspension from which the magnetic head slider was detached.
Claims11
A manufacturing method of a head gimbal assembly comprising the steps of:
- mounting a magnetic head slider with at least one thin-film magnetic head element on a wireless suspension, said mounting including a) using a resin adhesive to fix the magnetic head slider to the wireless suspension and b) electrically connecting said magnetic head slider with said suspension with ball bonding connections;
- inspecting electrical property of said at least one thin film magnetic head element;
- separating said ball bonding connections when determined that said at least one thin-film magnetic head element has defective electrical property;
- detaching said magnetic head slider from said suspension by heating a part of said magnetic head slider and a part of said suspension to loosen the resin adhesive used to fix said magnetic head slider to said suspension;
- and
- mounting a new magnetic head slider with at least one thin-film magnetic head element on said suspension from which said magnetic head slider was detached.
