Patent ID: 7549567

Claim:
A component mounting method comprising the steps of: picking up a component by suction with a working face of a suction nozzle having a predetermined surface roughness; positioning said component such that its metal interconnect faces a metal interconnect of an object on which the components is to be mounted; pressing said component onto said object while applying ultrasonic vibration from an ultrasonic vibration source to the working face of the suction nozzle, thereby ultrasonic-bonding the metal interconnects of the component and object with friction generated therebetween; and applying ultrasonic vibration to the suction nozzle with its working face in contact with an abrasive for an appropriate time to generate friction between the working face and abrasive, thereby refining the working face to a predetermined surface roughness for subsequent picking up of components, wherein frictional abrasion to the working face is performed with an abrasive tape with the ultrasonic vibration of 60 KHz and 1 to 2 μm amplitude under a pressure load of 300 to 500 grams applied to the working face while moving the abrasive tape.
