(A02_01) P.E.C. recognition function
Select one of the following options to determine whether or not this
function should be used.
Disable : The P.E.C. recognition function is not used.
Enable : The P.E.C. recognition function is used.
P.E.C. recognition mode global
When "Enable" is selected in the "P.E.C. recognition function" text box,
select one of the following options as a global recognition mode.
Disable : The global recognition function is not activated.
1 Point : The global recognition function is implemented, using one
fiducial mark.
2 Point : The global recognition function is implemented, using two
fiducial marks.
3 Point : The global recognition function is implemented, using three
fiducial marks.

1-Point Recognition
Only the X and Y elements are corrected. The θ element (expansion,
etc.) is not corrected.

2-Point Recognition
Specify fiducial mark positions so that one fiducial mark is kept as
diagonally away from the other as possible.
Fig. 3B45
Avoid fiducial mark positions aligned horizontally or vertically
with each other as shown below.
Fig. 3B46
3-Point Recognition
Specify fiducial mark positions so that the triangle area formed by con-
necting the three points (three fiducial marks) becomes as large as
possible.
Fig. 3B47
When any two of the three fiducial 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 Recog-
nition".

P.E.C. recognition mode image
When "Enable" is selected in the "P.E.C. recognition function" text box,
select one of the following options as an image recognition mode.
Disable : The image recognition function is not used.
Enable : The image recognition function(2-point recognition) is
used.
U-N : The P.E.C. recognition is performed, regarding a unit
P.C.B. as one unit on the multi-unit P.C.B.

When the global recognition function is used together with the
image recognition function, both recognizing actions take
place but the placement coordinates are corrected according
to the result of the image recognition.
