摘要： A liquid dispensing apparatus, including a hollow horn having a central cylindrical cavity and a piezoelectric ring having a central opening. The piezoelectric ring is coupled to the hollow horn such that the central opening is in communication with one end of the central cylindrical cavity. A mesh screen is provided at the other end of the central cylindrical cavity. Liquid is delivered to an inner surface of the mesh screen through the central opening of the piezoelectric ring and the central cylindrical cavity of the hollow horn, and is dispensed from an outer surface of the mesh screen in the form of fine liquid droplets.

摘要： An apparatus and method for detecting the oscillation amplitude of a bonding tool includes a sensing unit disposed adjacent to and at a distance from the bonding tool. The sensing unit includes a pair of electrodes, a piezoelectric sensing layer located between the pair of electrodes, and a membrane associated with the piezoelectric sensing layer. The piezoelectric sensing layer becomes sensitive to ultrasonic vibrations and generates electrical voltage signals after being activated by a poling process. An optional pre-amplifier is used to amplify the signals generated from the sensing unit, and an oscilloscope is used to further process the signals.
