Abstract:
1. A driving mechanism for driving a detachment tool adapted to detach a chip from an adhesive tape to which the chip is mounted, comprising: a supporter for the detachment tool; a first actuator coupled to the supporter and operative to drive the detachment tool to move along a first axis perpendicular to the chip; a bearing holding the supporter; and a second actuator coupled to the bearing and operative to drive the detachment tool to move along a second axis perpendicular to the first axis, the first actuator being configured to drive the detachment tool along the first axis with respect to the chip in conjunction with the second actuator driving the detachment tool for movement along the second axis to provide controlled lifting of the chip for propagation of delamination between the chip and the adhesive tape; the second actuator being coupled to the bearing and decoupled from the first actuator such that an axial movement of the detachment tool along the second axis caused by the second actuator does not produce a corresponding axial movement of the first actuator along the second axis.
