SI0804004E-000 = YS12, YG12: Procedure for adjustment after installation of the machine
41/60
If the measured result does not meet the specified value:
The “XY offset shift” is supposed to be corrected by performing feedback.
If the result does not meet the specified value, please investigate the cause of the problem
and perform the relevant basic adjustment again.
Please refer to “C. When the variation and the abrupt shift are found in the mounting
result.”
B. If the mounting result data spreads in the X and Y directions
The mounting result data spreads in the X and Y directions in different way depends on the
mounting angle as shown in Figure 57
.
The value of “Index 2” varies depends on the pattern of the mounting result data.
This symptom indicates that some adjustment data may have changed from the factory setting.
Instead of performing feedback (saving the machine data) of the ACP correction value, please
perform readjustment of the following items (check the variation of the data), and then perform
ACP accuracy check again.
Note:
Even when the value of “Index 2” is 1.000 or above, the mounting result data may spread in the X
and Y directions. In this case, please perform feedback of the correction data instead of
readjusting the basic data.
Figure 57
1. Items to be adjusted of the basic data
Please perform adjustment for the following items:
Scale adjustment of the fiducial camera
Scale adjustment of the scan camera
Positioning of the scan camera
Adjustment of the Head Offset XY
If the machine is equipped with the multi camera:
When performing the adjustment of the head offset of the scan camera, the basic data
adjustment of the multi camera needs to be performed. Please perform “Camera scale
adjustment” and “Positioning” of the multi camera after completing the above
adjustments.

2. Perform ACP adjustment
Please make sure to perform feedback for ACP adjustment after readjusting the basic data.
3. Check the accuracy after correcting the data (feedback)
After saving the corrected value in the machine data, perform ACP accuracy check again.
If the measured result meets the specified value:
- Bring back the machine data and the data of the mounting result.
- If the machine is equipped with the multi camera Move on to “0 7. Accuracy adjustment
of the multi camera (Option).
If the machine is not equipped with the multi camera Move on to “8. Items to be adjusted
relating to the mounting accuracy of the machine”.
If the measured result does not meet the specified value:
If the accuracy does not meet the specified value, please investigate the cause of the problem
and perform ACP accuracy check and the relevant adjustment again.
C. When the variation and abrupt shift are found in the mounting result
If the mounting is unstable, the accurate data is not obtained. Therefore, the mounting result
cannot be improved no matter how many times the feedback is performed. Please investigate
the cause of the problem and take relevant measures.
[Items to be checked]
- Is the board clamped properly?
- Is the mark recognition performed with the contaminated mark or insufficient mark
information?
- Is the component supply unit feeding the component properly or the components are
picked up properly?
- Are the components recognized properly?
- Is the nozzle clean or secured properly?
- Are the lens of the camera and the lighting part clean?
- Is the camera mounted properly?
If any problem is detected, please take relevant measures and perform ACP adjustment
again.
When performing adjustment of the board edge clamp unit, the data of the following items
may need to be adjusted.
[Items to be adjusted]
- “PCB Height”
- “Head Offset Z”

7. Accuracy adjustment of the multi camera (Option)
If the machine is equipped with the multi camera, please perform accuracy adjustment of the multi
camera (sub camera) after the accuracy adjustment of the scan camera (main camera) is
completed.
7.1. The flow of the accuracy check and adjustment of the multi camera
Note:
When performing adjustment of the basic data (“Scale”, “Camera pos.” and “Head Offset”)
of the scan camera (main camera) in ACP adjustment, please perform “Scale” adjustment , and
“Camera pos.” adjustment of the multi camera before performing ACP adjustment of the multi
camera.
1. Perform ACP accuracy check and adjustment with 301A (313A) nozzle (Ceramic 1005).
2. Perform FAMF accuracy check and
adjustment with 304A (315A) nozzle (Glass QFP68 pin).
7.2. ACP accuracy check of the multi camera (1005 ceramic chip)
The tools required for adjustment, the board name and the adjustment procedure are the same as
that of the ACP adjustment of scan camera. Please refer to “5. How to check the mounting
accuracy (with ACP)” for details.
1. How to change the settings
Click on the [ACP] button on the main menu of CalibSm. Change the camera number of the
“Adjust Camera” item to “5-digital MultiC” on the “AutoRun/Measure” tab.
If the machine is equipped with two multi cameras: Front Digital 5 / Rear Digital 6
If the machine is equipped with only one multi camera: Wherever (Front or rear) the camera is
mounted, it is Digital 5.
Figure 58
2. Start ACP adjustment
Check the settings and click on the [All] button to start ACP adjustment.
3. Perform feedback for the ACP adjustment.
The workflow after completing the ACP adjustment of the multi camera is basically the same
as that of the scan camera (main). Please refer to “5.2.2. Mounting and measurement
performed by ACP” for the adjustment procedure.
