Abstract

Inspection a is executed between a step B of mounting a chip component by a high-speed mounter and a step C of mounting a odd-shaped component by a odd-shape mounter. The inspection a executes not only mounted component inspection for determining a mounted state of a chip component mounted in the preceding step but also component fly inspection for determining whether a chip component is flown to a position where a odd-shaped component is mounted in the next step C. It is possible to execute the component fly inspection in accordance with a condition corresponding to the situation of an actual spot such as a case in which it is detected that a component is missing in mounted component inspection or a case in which the replacement date of an attracting nozzle in a high-speed mounter is approaching.
