| Summary: | A printed circuit board is fabricated in a manufacturing process. In an inspection process, first and second light sources of an inspection device irradiate the printed circuit board with first and second light having first and second wavelength distributions. First and second imaging devices produce a monochromatic first image and a color second image of an inspection subject region of the printed circuit board based on the first and second light respectively reflected by the printed circuit board. Presence and absence of a defect is determined based on at least the first image by automatic optical inspection. Further, verification of the defect is performed by visual observation of at least the second image. |
