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 tunable vibration absorption device is provided that is suitable for active or semi-active vibration absorption or damping of vibrations in vibrating structures. It comprises a stack including a force actuator mechanism for generating an axial actuation force and a force sensor mechanism which is responsive to an external force acting on the stack to generate a force signal. A controller unit is electrically connected to the force sensor mechanism for receiving the force signal generated by the force sensor mechanism, and it is also electrically connected to the force actuator mechanism for adjusting the axial actuation force generated by the force actuator mechanism in response to the received force signal generated by the force sensor mechanism.

摘要： An alignment tool for a bonding apparatus comprises a loading surface for receiving a pushing force from a surface of a device which is attached to the bonding apparatus, the loading surface being arranged and constructed to experience a tilting moment upon receiving an unequally distributed pushing force from a misaligned device acting on it. The loading surface transmits the tilting moment experienced by it to a sensing surface which is operatively connected to the loading surface through a columnar body, which has a smaller width than the loading surface and the sensing surface, and which connects the loading surface and the sensing surface. An array of piezoelectric elements communicates with the sensing surface and produces electrical signals in response to the tilting moment such that a computing unit operatively connected to the piezoelectric elements may detect a direction of tilt of the loading surface from the electrical signals produced by the piezoelectric elements.

摘要： There is disclosed a method and apparatus for ensuring release of objects such as solder balls from a pick head in a transfer and placement apparatus, comprising causing said pick head to vibrate by applying a vibration signal to said pick head over a range of frequencies. The range of frequencies is chosen such that it bounds the resonant frequencies of the pick head which may be calculated by computer simulation.
