Abstract

PURPOSE:To form compact positioning mark of a printed circuit board for electronic part mounting and type identification mark of the printed circuit board. CONSTITUTION:A mark 10 is provided on non-forming area of a circuit on the substrate body 2 of a printed circuit board 1. In the mark 10, an internal circle 11 and an external circle 12 are arranged concentrically. The area in the internal circle 11 is recognized for positioning of the printed circuit board, while the area between the internal circle and external circle has a pattern formed by bit detecting portions a, c, e, g consisting of conductor film pattern and bit detecting portions b, d, f, h consisting of substrate surface pattern. The bit detecting portions are recognized for type identification. Compact pattern can be obtained by using concentrically formed marks.

The conventional printed circuit board requires the discarding ear portion 42 for printing the bar code 46 for identifying the model. As the density of the printed circuit board increases, the area where the barcode 46 is printed is the board body 4
This is because it cannot be secured at 1. Since the discarding ear portion 42 has nothing to do with the original function of the printed circuit board, it is necessary to cut it away after mounting all electronic components. Therefore, the conventional printed circuit board needs a function of cutting off the discarding ear portion 42, which causes a problem that the mounting equipment becomes large and complicated. Further, it is necessary to incorporate a bar code reader for reading the bar code 46 into the mounting equipment, which makes the equipment larger and more complicated.
