INSPECTION DEVICE OF SOLDER MATERIAL AND INSPECTION METHOD OF SOLDER MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an inspection device of a solder material and an inspection method of the solder material capable of simply enhancing measuring precision of a degradation level of the solder material.

SOLUTION: The inspection device of the solder material and the inspection method of the solder material include: a light projection part for irradiating the solder material applied to the surface of the base material to be flattened with irradiation light; a light receiving part for receiving the diffused reflected light of the light projected from the light projection part; a housing which houses the light projection part and the light receiving part and a window part capable of permitting the irradiation light and the diffused reflected light to pass; a support part for supporting the housing at a predetermined height from the surface of the flattened solder material, and a processing part for processing the output signal of the light receiving part. The processing part allows the light receiving part to detect the diffused reflected lights obtained from a plurality of the different regions of the surface of the solder material according to a relative change in the horizontal positions of the surfaces of both of the housing and the solder material to collect a plurality of light receiving data and inspects the degradation level of the solder material on the basis of a plurality of the light receiving data.
