* A characteristic point(s) that can be used for recognition is (are) flashing when an area is
selected. If you include many unstable shape portions of a component or many portions not
flashing, the system may recognize an element by mistake in some cases.
● Add polarity mark window
Check off this check box when you are to create the direction judgment definition when you
select “Positioning 2” or “Positioning 3” as the “Operation mode.”
● Correct angle
- None
This is set by default.
- Circumference
Select this when an electrode(s) and/or a mark(s) are arranged on the circumference of a
component. If you select “None” for such a component, the system may recognize an
element by mistake.
● Insp. algorithm
Select this when you select “Positioning 2” as the “Operation mode.”
- Brightness
The system determines the direction by the
brightness.
- Standard Deviation
The system determines the direction by the
variance in density.
● Brightness
Specify this when you select “Positioning 2” as the “Operation mode” and “Brightness” as
the “Insp. algorithm.”
- Bright
Specify this when a bright mark or electrode in
the area for determining the direction.
- Dark
Specify this when a dark mark or electrode in the
area for determining the direction.
● Deviation
Specify this when you select “Positioning 2” as the “Operation mode” and “Standard
Deviation” as the “Insp. algorithm.”
- Large
Specify this when the density difference of the
area for determining the direction is large.
- Small
Specify this when the density difference of the
area for determining the direction is small.

⑧ Saving
After you finish teaching and setting all data, the system recognizes a component.
After recognizing a component, the system displays the screen for saving information on the
result of measurement.
a) Press the <Save> button to save the component vision data. After the system saves the
data, this <Save> button changes to the <Exit> button.
b) Press the <Exit> button to quit the dialog box for performing the vision teaching operation,
and then return to the dialog box for setting the vision teaching operation.
c) When you press the <Cancel> button, the system discards the result of the vision teaching
operation, and then closes the dialog box for performing the vision teaching operation.
d) When you press the <Re-setting> button, the system starts the vision teaching operation
from the beginning again.

4.5.7.7 Bad mark teaching
This command uses the OCC unit to check whether to produce each circuit, and teaches the
coordinates of a bad mark.
(1) Operation for teaching a bad mark
1) Teaching a bad mark
When you select the [Bad mark teaching] command, the following dialog box appears on the
screen.
① Position on Bad Mark
Specify the coordinates of the position at which a bad mark is located on a board. You can
set these coordinates by teaching them.
② Position off Bad Mark
Specify the coordinates of the position at which no bad mark is located on a board. You
can set these coordinates by teaching them. As this position, specify the position
between which the system can distinguish the contrast and that of a bad mark.
③ Set OCC Bad Mark Threshold
Set a threshold value for recognizing a bad mark.
The system automatically determines the threshold value by recognizing a position of a bad
mark and that where no mark is located with teaching operation.
④ Vertical Light Parameter
⑤ Inclined Light Parameter
⑥ Contrast Pattern
⑦ Window Frame (Width, Length)
⑧ Mark Polarity
As an initial value, “***” appears in each of the fields above.
If the system obtains the threshold value successfully when you perform teaching operation
for the “Set OCC Bad Mark Threshold” field to recognize a position of a bad mark and that
where no bad mark is located, the recognized value is set in each of these fields.
