ABSTRACT:
The present invention provides a system and method for providing a improved device for dismounting integrated circuits for rework tools in the fabrication and manufacture of hard disk drives. Embodiments of the present invention include a vacuum cap with suction capabilities for dismounting the integrated circuits. The vacuum cap includes a cylindrical portion with a vacuum path for holding a rod-like vacuum cylinder which when pressurized causes the integrated circuit to dismount. Embodiments of the present invention further include a light weight aluminum heat-shield that is disposed around the vacuum cap to protect the vacuum cap from excessive heat and to preserve the suction capabilities of the vacuum cap. In one embodiment the heat shield acts as a stopper to prevent the vacuum cap from moving upwards and helps the vacuum cap from absorbing multiple mechanical stress in order to protect the vacuum cylinder from being damaged.
