ABSTRACT:
A soldering inspection system wherein light is irradiated on a soldered part at different incident angles by a light emitting means to collect information indicative of three-dimensional configuration of the soldered part and discriminate whether or not the configuration is acceptable. The three-dimensional configurational information can be obtained with light irradiated at least from two positions mutually of different angles with respect to the soldered part, the inspection is thereby made from quantitative viewpoint, and a highly precise result of the inspection is obtainable.
