ABSTRACT:
There is disclosed an electronic parts mounting method in which it is possible to avoid a pick-up mistake for electronic parts (chips) in simultaneously picking up the chips respectively stored in juxtaposed parts feeders by a plurality of nozzles provided to a transfer head. Nozzle position data of first, second and third nozzles 9a, 9b and 9c are beforehand obtained by a first camera, and pick-up positions of the chips in parts feeders 4 are obtained by a second camera. After picking up respectively the chips in the parts feeders 4 by the nozzles 9a to 9c it is judged whether or not there would be caused the pick-up mistake. When it is judged there is caused no pick-up mistake, a transfer head is moved to a position above a board and each of the chips is mounted to the board. When it is judged there is caused any pick-up mistake, a pick-up mistake rate of any of the parts feeders in which the pick-up mistake occurs, is updated and each of the chips is picked up again by the nozzle which caused the pick-up mistake.
