Abstract:
1. A method for rebuilding a head stack assembly, the head stack assembly including a carriage having a plurality of actuator arms and a plurality of head gimbal assemblies, to each head gimbal assembly a base plate of a mount plate is fixed, and in each of which a boss of each mount plate is swaged into one of the plurality of actuator arms, the method comprising: mounting the head stack assembly in a jig; facing a shearing edge of a reworking tool to contacting surfaces of the base plate and a first actuator arm; depositing a volatile alcohol solvent on the shearing edge of the reworking tool; letting the shearing edge of the reworking tool slide on a surface of the actuator arm to insert the shearing edge of the reworking tool in the contacting surfaces of the base plate and the first actuator arm and thereby removing the mount plate together with a first head gimbal assembly from the first actuator arm; and securing another head gimbal assembly to the first actuator arm, from which the first head gimbal assembly has been removed, through a swaging operation.
