Abstract
A driving mechanism and method are provided for driving a detachment tool adapted to detach a chip from an adhesive tape to which the chip is mounted. The mechanism includes a first actuator coupled to the detachment tool and operative to drive the detachment tool to move along a first axis substantially perpendicular to a surface of the chip, and a second actuator coupled to the detachment tool and operative to drive the detachment tool to move adjacent to a width of the chip along a second axis perpendicular to the first axis. The first actuator is configured for programmable movement along the first axis with respect to the chip in conjunction with the second actuator for movement adjacent the width of the chip to provide controlled lifting of the chip for propagation of delamination between the chip and the adhesive tape.
