Memo On Fiducial Marks
A fiducial mark has to satisfy several shape and material conditions.
During the design of PCB, the following precautions should be taken.
8 patterns of fiducial mark shapes are possible as shown in the
figure below (top/bottom symmetry or right/left symmetry)
For the size of A, over 2.0? is recommended. The width of mark
sensor beam is about ø0.7? measured from the surface of PCB
Make sure that any changes in color or shape (solder resist, lead
pattern) that can cause error should not be found within 2.0?of
fiducial mark's outer edges.
Make sure that the shading difference exits between the fiducial
mark and the board surrounding it.
To ensure search accuracy, coat the surface of the fiducial mark with
copper or lead so that the surface does not reflect. The line shaped
fiducial marks can not be searched with Beam.
<5. Mark List> group
A list of fiducial mark shape data.
<No> column
A serial number of fiducial mark shape.
<Name> column
