Board inspection apparatus

A board inspection apparatus comprising:

• a surface-side irradiator that irradiates a surface side of each of a plurality of inspection areas of a board;
• a surface-side camera that takes a surface-side image of the surface side irradiated by the surface-side irradiator;
• a rear face-side irradiator that irradiates a rear face side of each of the inspection areas;
• a rear face-side camera that takes a rear face-side image of the rear face side irradiated by the rear face-side irradiator;
• and
• a controller that:
• moves the surface-side irradiator and the surface-side camera to a position corresponding to the surface side of each of the inspection areas;
• moves the rear face-side irradiator and the rear face-side camera to a position corresponding to the rear face side of each of the inspection areas;
• and
• inspects the surface side and the rear face side of each of the inspection areas based on the surface-side image and the rear face-side image, respectively, wherein
• the surface-side camera and the rear face-side camera alternately take the surface-side image and the rear face-side image, and
• the surface-side camera takes the surface-side image when the rear face-side irradiator stops the irradiation, and subsequently the controller moves the surface-side irradiator and the surface-side camera to a position corresponding to a surface side of a next inspection area and the rear face-side camera takes the rear face-side image when the surface-side irradiator stops the irradiation, or
• the rear face-side camera takes the rear face-side image when the surface-side irradiator stops the irradiation, and subsequently the controller moves the rear face-side irradiator and the rear face-side camera to a position corresponding to a rear face side of a next inspection area and the surface-side camera takes the surface-side image when the rear face-side irradiator stops the irradiation.
