Abstract
The a system includes a visual inspection unit, a plating thickness inspection unit, and a shape inspection unit, suitably arranged in combination on the inspection line for automatic inspection of stains, flaws, glossiness or deformation in plated IC lead frames. The system can be used by an inventive method to correct errors in positional relation between a reference image and images input from an inspection camera, to obtain a comparison between a reference luminance curve and the individual luminance curves and the correlation between reflectivity and the corresponding area, and to obtain a comparison between the reference correlation and individual correlations to thereby enhance automation and precision in inspection IC lead frames.
