Abstract
A packaged substrate inspecting apparatus comprises an imaging device for picking up images of substrates. Land images are extracted from the image of a non-packaged substrate and that of a packaged substrate. On the basis of the shapes of the land extracted from the non-packaged substrate and those of the packaged substrate, positional relationship between a part mounted on the packaged substrate and the land is determined to be utilized for deciding whether the mounted state of the part on the substrate is to be satisfactory or not.
