Abstract

PURPOSE: To confirm the position of a defect accurately by providing an optical system wherein the address display of a confirming film that is arranged on a first positioning table is made to agree with the surface of a printed wiring board to be inspected that is arranged on a second positioning table and the address display is projected.
CONSTITUTION: The position of a printed wiring board whose electrical inspection is finished is determined with positioning pins 7a on the surface of a second positioning table 7. Then, the position of a confirming film 3 wherein the result of the electrical inspection and the position of a defect are attached is determined with positioning pins 6a on the surface of a first positioning table 6. Then, a light source 8a of an optical system 8 is operated, and the light is emitted on the film 3. The position of the detect which is attached on the film 3 is projected on the surface of the board 2 through the table 6 and a projecting lens 8b. The relative positions of the film 3 and the board 2 are aligned with the tables 6 and 7. The optical system 8 is adjusted so that the projected image of the film 3 agrees with the circuit pattern of the board 2. Therefore, the position of the defect of the film 3 is accurately superimposed on the surface of the board 2 and visually confirmed.
