WIRING PATTERN TREATMENT APPARATUS

摘要

PROBLEM TO BE SOLVED: To detect with high precision defects in a wiring pattern formed on a wiring board. SOLUTION: A wiring pattern display apparatus irradiates the wiring board 1 with light and displays the wiring pattern 2 formed on the wiring board 1 by means of the reflected light of the light. The apparatus comprises: a plurality of irradiation means for generating a plurality of lights having different wavelengths and irradiating the wiring board 1 with the lights from a plurality of different directions; a wavelength separation means for separating the wavelengths of the reflected lights of the lights irradiated on the wiring pattern 2 from the irradiation means; and a display section for displaying the wiring pattern 2 in accordance with the light with the wavelength separated by the wavelength separation means.
