ABSTRACT:
A component-mounted printed circuit board inspecting apparatus comprises an imaging device for picking up images of printed circuit board. Land images are extracted from the image of a bare printed circuit board and that of a component-mounted printed circuit board. On the basis of the shapes of the land extracted from the bare printed circuit board and those of the component-mounted printed circuit board, the positional relationship between a comonent mounted on the printed circuit board and the land thereon is determined. This positional relationship is utilized to decide if the component is mounted properly on the printed circuit board.
