    Patent number: 9299372
    Abstract: A device for loading a first and second head gimbal assemblies (HGAs) onto an actuator pivot flex assembly (APFA) of a hard disk drive may comprise a gripper configured to grip the HGAs and to move them between the first and second actuator arms of the APFA. A swage key may be moved to a first position such that first and second distal portions thereof are respectively disposed between the first and second HGAs, and to a second position such that the HGAs are supported, respectively, by first and second localized humps defined on the swage key and aligned with boss holes of the APFA. The swage key may be moved to a third position such that the HGAs face first and second proximal portions of the swage key and become seated onto the boss holes.
