Electric-component mounting system

摘要

Method of transferring an electric component from a component supply device to a suction nozzle of a component-holding head, wherein a relative position between a sucking surface of the suction nozzle and an axis of rotation of the component-holding head is obtained, and the component-holding head and the component supply device are moved relative to each other on the basis of the obtained relative position, so as to minimize an error of relative positioning between the sucking surface and a predetermined sucking position of the electric component positioned at the component-supply portion. The head and the component supply device are then moved toward each other, for transferring the electronic components from the component supply device to the suction nozzle. Also disclosed is an electric-component mounting system arranged to practice the method before the electric component is mounted on a circuit substrate.
