Method and device for mounting electronic component

摘要

In a component mounting device in which a component is picked up and mounted on a circuit board by a suction nozzle, an amount of displacement between a center position of the suction nozzle (11) and that of the picked-up component (12) is measured, and when it is larger than a preliminarily determined value, a warning is generated indicating that the parts cassette (3) from which the component (12) has been fed is in abnormal condition, as well as the mounting action of the component (12) is stopped.
