Patent ID: 7952713

Claim:
A bonding agent sticking inspection apparatus comprising: a photographing section for photographing an image of a substrate on which a plurality of electrodes are arranged at predetermined pitches between electrodes in such a manner that the image includes a sticking expected range indicating a range in which a bonding agent to be interposed between the electrodes and a component to be electrically connected to the electrodes should be positioned; a movement section for guiding the substrate into a visual field of the photographing section; and a control section for controlling the photographing section and the movement section in order to photograph an entire region of the sticking expected range, setting an inspection region having a width equal to the pitch between electrodes in an entire edge part in a direction in which the electrodes are arranged in a peripheral edge part of the sticking expected range in the image photographed by the photographing section, detecting a ratio of a nicked part of the bonding agent to the inspection region, and judging whether or not an abnormality is present in the bonding agent on the basis of a comparison between the ratio of the nicked part and a threshold set in advance.
