Abstract:
A bonding method for a bonding apparatus in which a position-detecting camera that detects a position of a part to be bonded and a tool that performs bonding are offset, the method comprising the steps of:moving the position-detecting camera to a point above a reference marking on a reference member, measuring the positional relationship between the reference marking and an optical axis of the position-detecting camera by the position-detecting camera, moving the tool to a point above the reference marking in accordance with an amount of offset stored in memory beforehand, measuring the positional relationship between the reference marking and the tool by an offset-correcting camera, and correcting the amount of offset stored in memory beforehand on the basis of the measurement results, thus determining a desired accurate amount of offset.
