2.3 Operation Data
Checker (Rectangle)
Thru Hole
(Round)
Pad Mark
(Rectangle)
(a) A through hole or a pad mark should have only one land
which is directed in increments of 45°.
Consult our marketing department for details such as di-
mensions, etc.
(b) 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.
Example:
Unit: mm
(Front Side of Machine)
Fig. 3B60
(c) The shape of P.C.B. (a cutout, a punched hole), the exter-
nal elements (light reflected from a structure, light emitted
from an external device, etc.) may sometimes interfere with
recognition. Consult our marketing department for details.
(d) A fiducial mark should make ample contrast with the sur-
roundings. (To prevent false recognition)
(e) Anything resembling a pattern similar to a fiducial mark
should not exist in the designated window. If one exists, it
may cause false recognition.
(f) A test may be required when the fiducial mark cannot be
recognized because of the extreme warpage of the P.C.B.
