Abstract
The maintenance of nozzles is carried out efficiently and smoothly by automatically identifying a defective nozzle, hence contributing to the increase of productivity. A method of mounting electronic components implemented in an electronic component mounting apparatus which includes an electronic component mounting means (7) provided with a plurality of nozzles (13) for attracting by suction and mounting electronic components (14), an imaging means (15) for shooting an image of the electronic component (14) held by the nozzle (13), and a recognition controlling means (16) for analyzing the image of the electronic component (14) recorded by the imaging means (15) to inspect the condition of the electronic component (14) being attracted, comprises the steps of taking an image of a tip surface of the nozzle (13) with the imaging means (15) which has repeated a suction error by a specific number of times, analyzing the image with the recognition controlling means (16) to inspect the condition of the tip surface of the nozzle (13), and judging the said nozzle (13) as a defective nozzle.
