Abstract:
1. A solder printing inspection apparatus for inspection of solder printed on a circuit board having a multiplicity of lands for mounting of electronic components, the solder printing inspection apparatus comprising: an irradiation unit that irradiates a light on the circuit board; an imaging unit that images the circuit board irradiated by the light; a solder bridge detection unit that detects a solder bridge connecting at least two of the lands based on an image data imaged by the imaging unit; a detection unit that extracts two lands, solder printing regions, or solder inspection frames having a farthest positional relationship among at least two lands contacting a single solder bridge or a solder printing region or solder inspection frame set corresponding to such lands; a distance calculation unit that calculates, as a bridge distance, a minimum distance between the extracted two lands, solder printing regions, or solder inspection frames; a distance determination unit that determines whether or not the bridge distance is within a permissible range; and a severe defect processing unit that performs a certain severe defect processing when the bridge distance is determined not to be within the permissible range, wherein the solder printing inspection apparatus further comprises a memory unit that remembers various types of setting data relating to manufacture of the circuit board, and the solder bridge detection unit, based on the setting data, sets a bridge inspection frame for detection of the solder bridge.
