Abstract:
1. A die bonding method for successively bonding chips to a plurality of chip-mount portions disposed on a substrate, said method including: a bonding step that bonds a chip to a chip-mount portion by a bonding head; a bonding preparation step that moves said bonding head to a chip supplying portion to pick up a new chip and then moves said new chip to said chip-mount portion where a next bonding operation is performed; an imaging step which is performed in parallel with said bonding preparation step, said imaging step imaging only once a chip-mount portion both for inspection, which is a chip-mount portion where bonding has just been performed, and for position-detection, which is a chip-mount portion where bonding is going to be performed, and said imaging step being performed by an imaging device in which said plurality of chip-mount portions are contained in same visual field thereof; a position detection step that detects a position of said chip-mount portion for position-detection based on acquired image data; and an inspection step that inspects a state of bonding of said chip-mount portion for inspection based on acquired image data.
