(4) Specifications of Lines extended from a Pad Mark or a Through Hole
Unit: mm
Fig. 3B69
(a) A through hole or a pad mark should have only one land
which is directed in increments of 45°.
Consult our marketing department or sales agency for
details (dimensions, 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:
(Front Side of Machine)
Unit: mm
Fig. 3B70
(c) The shape of P.C.B. (a cutout, a punched hole) and the
external elements (light reflected from a structure, light
emitted from an external device, etc.) may sometimes in-
terfere with recognition of the fiducial marks. Consult our
marketing department or sales agency 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.
