PEC recognition function
Select one of the following options to determine whether or not this function
should be used.
Disable
: The PEC recognition function is not used.
Enable
: The PEC recognition function is used.
Notice
When the PEC recognition function is not used in a pattern program,
the program cannot be used.
(C01_02)
All (Zones 1 through 5)
When the "PEC recognition function" is to be used, the setting for the global
recognition is selected from the following items for each zone.
Disable
: The global recognition function is not activated.
1 Point
: The global recognition function is implemented, using one ducial
mark.
2 Point
: The global recognition function is implemented, using two ducial
marks.
3 Point
: The global recognition function is implemented, using three
ducial marks.
Note
(a) It is recommended that "2 Point" or more should be selected for the
global recognition.
(b) By dividing the area for the PEC recognition into several zones, it
became possible to correct a local expansion of a large PCB, etc.

•
1-Point Recognition
Only the X and Y elements are corrected. The θ element (expansion, etc.) is
not corrected.
Fiducial Mark
F2B16
•
2-Point Recognition
Specify ducial mark positions so that one ducial mark is kept as diagonally
away from the other as possible.
Fiducial Mark
PCB
F2B17
Note
Avoid making positional relation such as ducial marks aligned vertically
or horizontally with each other as shown below.
F2B18
•
3-Point Recognition
Specify ducial mark positions so that the triangle are formed by connecting
the three points (three ducial marks) becomes as large as possible.
Fiducial Mark
F2B19
Note
When any two of the three ducial marks are designated to be positioned
as close as possible to each other, the results of the correction will be
almost the same as "2-Point Recognition".
