Abstract:
A mounting apparatus of a flip-chip having a plurality of bonding areas said bonding areas constituting bumps, utilizing ultrasonic wave and thermocompression bonding to form a flip-chip bonding system which monitors the connection of a plurality of bonding areas on said flip-chip to assure a non-defective bond thereof comprising:an ultrasonic vibration generating device; a horn attached to the ultrasonic vibration generating device; a collet tool for holding a flip-chip attached to said horn; a control unit being connected to the ultrasonic vibration generating device; a substrate conductor heating unit connected to said control unit; a height measuring device for monitoring a height of the flip-chip with respect to a substrate conductor connected to the control unit, by monitoring a first bump sinking amount and a second bump sinking amount of a flip-chip having a plurality of bumps thereon; and a vibration measuring device for monitoring a vibrating state of a plurality of bonding areas of the flip-chip connected with said control unit; wherein the control unit controls operation of the ultrasonic vibration generating device based on change in height between the flip-chip and the substrate conductor heating unit and on the vibrating state of the plurality of bonding areas of the flip-chip.
