14.3.7.10. Fly to Fix Camera & Fly Runout Offset Calibration
The calibration is performed to compensate the offset that occurs due to the difference
between the ‘part-alignment height’ and placement height when placing the part after part-
recognition by the fly-camera.
The offset that occurs this time is caused by the run-out, bending of an axis, etc. Perform
compensation of the value at the recognition height of the fly camera and fiducial camera,
which are the same as the placement height.
In order to perform this calibration, the ‘Fly-Camera Offset Calibration’, ‘Fix-Camera
Scale Calibration’ and ‘Head Offset Calibration’ must be performed first and the CNT20
nozzle must be used.
The following is the procedure to calibrate the ‘Fly to Fix Offset’
1. Click the <Nozzle Prepare> button and insert the CNT20 nozzle into the No. 1 hole of
the ANC manually.
2. If the <14. Fly to Fix Offset> is clicked after selecting the <Automatic Next> check
box, calibration is performed for the selected gantry automatically.
If calibration is performed after selecting the <No Real Motion [Manual]> check box,
the nozzle is inserted into each head manually. Click the <Next> button to move onto
the next step.
If calibration is performed without selecting either the <Automatic> check box or
<Manual> check box, the nozzle is changed automatically for the currently selected
nozzle. Click the <Next> button to move onto the next step.
If the <14. Fly to Fix Offset> button is selected, the message “First, We must Put all
Nozzles From Heads on Manually. To Move down Z Axis, Click [Next]” appears.
Click the <Next> button to move down the Z-axis of the head in order to manually
move all nozzles inserted in the nozzle-holder of the head.

3. Then, after the head assembly moves to the designated position, move all Z-axes
down. At this time, remove all inserted nozzles manually.
4. Then the message “Next Attach the Calibration Tool to Head 1. Click [Next] for
Moving Down Head. After Moving, Attach the Tool to Head Manually” appears.
Click the <Next> button after inserting the CNT20 nozzle in the nozzle-holder of
Head #1 manually.
5. The message “Move To Center Position of [Fix1] Camera. To Move, Click [Next]”
appears. Click the <Next> button to move the head assembly to the center of the Fix1-
Camera. At this time, select the ‘Fix Cam1’ in the <Target Camera> combo box. Click
the <Light…> button and adjust the brightness of the light in the ‘Light Control’
dialog box so that the fiducial mark on the CNT20 nozzle that is seen in the
‘SMVision’ window can be seen clearly.
6. Then the message “Up to Align Height and Mirror Close, Click [Next]” appears. Click
the <Next> button.
7. Next, Head 1 moves up to the align height of the Fly Camera and the mirror is closed.
Then the message, “Calibration is Prepared. To Calibrate, Click [Next]” is displayed in
the message window. At this time select the ‘Fly Cam1‘ in the <Target Camera>
combo box and, in the ‘Light Control‘ dialog box, adjust the brightness of the lighting
so that the ‘Fiducial Mark’ on the CNT20 nozzle can be clearly seen in the ‘SMVision
‘ window. Then click the <Next> button.
8. The calibration is performed automatically. If it is completed, the calibration result is
displayed as shown in the following figure. Click the <Next> button.
9. From Head #2 to Head #10, perform calibration in the same manner as it was
performed for Head #1.
10. If the calibration procedure is completed for all heads normally, the result is displayed
as shown in the following figure. Click the <Update> button to apply the calibration

value.
11. The measurement result can be confirmed in the Fly-Fix Offset dialogbox.
Memo The reference values for the calibration of the Fly to Fix Offset is as
follows.
Offset X : -0.050 ~ 0.050(mm)
Offset Y : -0.050 ~ 0.050(mm)
The reference values for the calibration of the Fly Runout Offset is as
follows.
Offset X : -0.020 ~ 0.020(mm)
Offset Y : -0.020 ~ 0.020(mm)
