1.2 Operation Data
Regulations regarding Mark Surroundings
• A fiducial mark should make ample contrast with the surround-
ings. (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 or salse agency 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 plate and the settings of screen fiducial
marks.
