Regulations regarding Mark Surroundings

• A fiducial mark should make ample contrast with the surroundings. (Preven-

tion of False Recognition)

• The shape of P.C.B. (a cutout, a punched hole), the external elements (light

reflected from a structure, light emitted from an external device, etc.,) may

sometimes interfere with recognition.

(Consult our marketing department for details.)

• A copper leaf, a resist, a coating, a silk print, and a punched hole should not

exist in the range of 1.0 mm in both X and Y directions from the outermost

edges of a fiducial mark. They may cause false recognition.

• Anything resembling a pattern similar to a fiducial mark should not exist in

the designated recognition area. If one exists, it may cause false recogni-

tion.

Refer to "Chapter 2" in "Volume 1" for the material of the screen
