Abstract
An expandable gripper for semiconductor processing equipment that allows the pitch between semiconductor chips to be adjusted. To adjust the pitch, several pick and place mechanisms are mounted around a shaft using nuts. The threads of the nuts have variable leads, causing each to travel a different amount as the shaft rotates. All of the threads engage the shaft because a compliant layer is attached to the shaft.
