Abstract:
A method of mounting an electric component on a circuit substrate, the method comprising the steps of:moving at least one of a suction nozzle and an electric-component supplying device toward the other of the suction nozzle and the electric-component supplying device, so that the nozzle applies a suction to the electric component supplied by the supplying device and thereby receives the component, moving at least one of the suction nozzle and the circuit substrate toward the other of the nozzle and the substrate, so that the nozzle mounts the electric component on the substrate, taking an image of at least a portion of the electric component sucked and held by the suction nozzle, as seen in a direction perpendicular to an axial direction of the nozzle, in a state in which the nozzle takes a known position in the axial direction, determining, based on image data representing the taken image, a position of at least a mounted surface of the electric component that is opposite to a sucked surface of the component sucked by the suction nozzle, and controlling, based on the determined position, a movement of at least one of (A) the suction nozzle and (B) at least one of (b1) the electric-component supplying device and (b2) the circuit substrate, toward the other of the nozzle and said at least one of the supplying device and the substrate.
