Patent ID: 7861908

Claim:
A component mounting apparatus for mounting a component having a plurality of bump electrodes on one face thereof onto leads of a mounting object, comprising: a component feeder for feeding the component with the bump electrodes facing down; a mounting head for holding the component and mounting the component onto the mounting object; a supporting base for securing the mounting object; and a positioning device for moving the mounting head relative to the supporting base to align the component with the mounting object, wherein said mounting head includes: an ultrasonic vibration generator, an ultrasonic vibration propagation member including an oscillator having a working face configured to hold the component, and a connecting rod connecting the ultrasonic vibration generator to the oscillator and disposed so as to convey ultrasonic vibration provided by the ultrasonic vibration generator along a direction to the working face such that a vibrating direction of the ultrasonic vibration is substantially parallel to the working face, a pressure loader for applying a pressure load to the working face of the ultrasonic vibration propagation member, a heater for heating a vicinity including the working face, and a thermal transfer unit defining a chamber having an inlet which provides a flowing heat transfer medium and configured to effect at least one of cooling or heat retaining via the connecting rod, and the chamber encompassing at least a portion of the connecting rod and containing the flowing heat transfer medium in direct contact with the connecting rod.
