Abstract

In a circuit board, a fiducial mark (2) of the same material as that of a circuit pattern is formed on a main surface of a board (1) on which the circuit pattern is formed, and it is coated with a solder resist film (3). According to this circuit board, it is possible to carry out position recognition by irradiating infrared rays without exposing the fiducial mark (2), so that oxidation of the fiducial mark (2) or attachment of solder thereto are prevented. An apparatus for recognizing the position of a circuit board includes means (22) for picking up the image of the surface of a circuit board (20), means (23) for recognizing the position of the circuit board (20) from thus obtained image, and means (21) for irradiating infrared rays toward the circuit board (20). In another arrangement the apparatus is used to detect the position of part of the wiring pattern rather than a fiducial mark. FIG.6 <IMAGE>
