Overall P.C.B. B.B.R. Detection Function
If most of the unit P.C.B.’s are not defective (bad mark attachment
not required) but the machine implements the unit P.C.B. bad board
reject function on every unit P.C.B., the production rate of the ma-
chine will deteriorate. To avoid this, the overall P.C.B. B.B.R. detec-
tion function becomes effective.
When this function is activated, the machine implements the overall
P.C.B. B.B.R. detection function to detect a bad mark on the overall
P.C.B. before the implementation of the unit P.C.B. B.B.R. detection
on each unit P.C.B. If no bad mark is detected on the overall P.C.B.,
the machine does not implement the unit P.C.B. B.B.R. detection
function on each unit P.C.B. of the multi-unit P.C.B. because each
unit P.C.B. is considered "Defect-Free".

2.3 Operation Data
When "Enable" is set in the "Overall P.C.B. B.B.R."
text box, be sure to put overall P.C.B. B.B.R. bad marks
on the bad-marked P.C.B.’s. Otherwise,
all unit P.C.B.’s are regarded as "Defect-Free".

(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.
Fig. 3B44
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".
