摘要： A damping apparatus is provided for a positioning stage that is operative to move and position an object along a motion axis. The damping apparatus comprises a motion transformation device operative to rotate the positioning stage about a rotary axis that is substantially perpendicular to the motion axis, in response to forces generated to the positioning stage during acceleration or deceleration thereof. Resilient elements connected to the positioning stage serve to reduce transmission of vibration generated from the positioning stage.

摘要： A die detachment apparatus for detaching a die from an adhesive tape on which the die is mounted includes a pick-and-place tool movable along a pick-up axis for picking up the die from the adhesive tape and a die ejector comprising an ejector shaft including an ejector pin. The ejector pin is movable parallel to the pick-up axis to raise the die from the adhesive tape to facilitate pick-up of the die by the pick-and-place tool. At least one movable table to which the ejector shaft is operatively coupled is actuable by at least one piezoelectric actuator which is connected to the movable table via a flexure. Actuation by the piezoelectric actuator forces the movable table and ejector shaft to move in directions which are perpendicular to the pick-up axis for alignment of the ejector pin with the die pick-up tool along the pick-up axis.
