Abstract
A board testing apparatus including: an image obtaining device that obtains an image of an inspection object area in a printed circuit board, the inspection object area including a component mounting area; and a control device that detects a foreign substance in the inspection object area based on the image, determines that the foreign substance is defective upon detecting that the foreign substance overlaps the component mounting area or is adjacent to the component mounting area when a lump part of the foreign substance has an area greater than an area threshold value or a length greater than a length threshold value, and determines that the foreign substance is non-defective upon detecting that the foreign substance neither overlaps the component mounting area nor is adjacent to the component mounting area even when the lump part has the area or the length.
