ABSTRACT:
A workpiece, on which electrically-conductive balls have been mounted by a mounting machine, is inspected by a camera of an inspecting device. The workpiece has a number of conductive ball-mounting areas arranged in a matrix-like pattern. The camera inspects each of the mounting areas independently with respect to the absence of the conductive ball, the misregistration of the conductive ball and the overload of the conductive balls. The defective workpiece, fed from the inspecting device, is stopped at a repair stage, and the operator effects a repairing operation at this repair stage. A monitor television is provided at the repair stage, and a defect category for each mounting area of the workpiece is displayed on a screen of this monitor television, and the operator effects the repairing operation while viewing this screen. Therefore, the burden of labor on the operator is reduced, and the repairing operation for correcting the mounting error can be effected easily and rapidly.
