3) Setting the shape of a mark
After setting the noise cut level, the system automatically recognizes the shape of the
mark, and then appends a “*” mark next to the corresponding mark displayed in the list
of mark shapes on the left side of the screen.
If the system misjudges the mark shape, press the top/bottom of the frame to select
the correct mark.
When you press the <OK> button, the system allows you to go to the next step.
4) Setting the detection frame
Next, the system teaches the detection frame.
After the mark shape is set, the system automatically displays the window whose size
is 1.5 times as big as that of the mark so that its center can be aligned with that of the
screen.
To change the position or size of the detection frame, set it in the same manner as the
scale frame.
When you press the <Prev> button at this point, you can return to the procedure for setting
the scale frame.
Set the detection frame in the same manner as the scale frame.
See “1) Setting the scale frame” for how to set the detection frame.
S After adjustm
ent, press the <OK> button.

5) Registering a mark
When the system finishes teaching a mark, the dialog box for registering mark data
into the database appears on the screen.
To register the taught data into the mark database, enter its name, and then press the
<Register> button.
To replace the mark data with that already registered in the database, select the data to be
replaced or enter its name directly, and then press the <Register> button. When the
following dialog box appears on the screen, select the <Yes> button.
If you do not want to register the taught data into the mark database, press the <Close>
button.
When the system finishes teaching operation for recognizing the mark, “OK” is displayed in
the field of the item next to the mark data to indicate that it has been already taught.
Perform teaching operation for recognizing all marks to be used.
* If there is no pattern to be taught on the screen, check to see if the entered coordinates
are correct.
* As for a mark (its color is white) on a ceramic board, press the “Teaching” button, and
then press the camera button of the “Device Select” column. The polarity is switched,
and the mark that has looked black on the board looks white. Switching of the polarity
with the camera button is effective only when the scale frame is entered.

• If the system cannot recognize a mark stably, press the "Light pattern setting" button to set
the light pattern. Be sure to set the light pattern before specifying the top side and left side
of the measurement frame.
When you use the <User defined> button, enter the light value directly.
Select the <Inclined> button, the <Vertical> button or the < OuterRing > button and enter
the desired value into the edit box directly, or change the displayed value with pressing
the <+> button or the <-> button.
* We recommend that you specify a value from 50 to 200 for a user-defined pattern.
If you specify 50 or a smaller value, the amount of light may become unstable.
The [OuterRing] button is displayed only when [Solder Print Misalignment Correction
(option)] is set.
If you want to teach only the inspection frame while holding the same information on a
mark, press the <Next> button. You can skip Step ③.
When the system recognizes a new mark, the <Next> button is disabled.
Light pattern Process
Standard Select this type if the system recognizes a normal BOC mark.
Resist/Cover Film Select this type if a mark is not reflected well with the standard type of
light because a resist or cover film is located over a mark, so the
system cannot recognize the mark stably.
User defined Select this type if a mark is not reflected with either type of the light
above, and the system cannot recognize a mark stably.
This selection allows you to set the light amounts of the vertical,
inclined and OuterRing lights directly.
