5. Board Recognition Marks
Create the board recognition marks under the following conditions.
(See Figure 1.1.7.2.) We recommend the filled circle for the mark.
The clearance area around the mark shall be as shown in Figure 1.1.7.3.
Within this area, there shall not be any silk patterns, strip lines (including inner
layer patterns), through holes, resists, and other components.
A size: 0.5 to 3.0 mm ± 10％
B size: 0.2 mm or more
C size: 0.5 to 3.0 mm ± 10％

Notes: 1. When recognition, the mark shall be placed in the angle shown above.
However, if you specify "Use of each circuit mark" for a non-matrix
PWB, the mark can be recognized only when all marks of the
reference circuit are positioned in the angle described and the circuit is
positioned at 90, 180, 270 or 360 degrees.
2. The fiducials of the same shape and same size is preferable within a
board.
3. When processing, copper foil or solder plating can be recognized.
4. Maximum number of marks which can be registered
Board mark: 1 set (2 marks or 3 marks)
IC mark: 50 sets (Pairs of 2 marks)
5. Items that can be registered

Normal/reverse rotation identification when detected
