ABSTRACT:
A component mounting method for successively mounting electric components on a printed circuit board, which method comprises the steps of recognizing the position of an electric component retained by a suction nozzle by the effect of a suction force; recognizing the predetermined mounting position on a printed circuit board or any other suitable substrate, at a location spaced a predetermined distance from the printed circuit board; mounting the electric component after the latter has been aligned with the predetermined mounting position on the printed circuit board; and recognizing, through the suction nozzle, the electric component to determine if the electric component has been mounted properly after the suction nozzle has been elevated to a position spaced a predetermined distance upwardly from the printed circuit board. In the event that the latter has been mounted incorrectly, information indicative of an incorrect mounting of the electric component is recorded in a control data.
