6. If “AMF index” falls below 1.0.when performing accuracy
check by ACP
If the measured results of “AMF index 1” and “AMF index 2” fall below 1.0, analyze the measured
data by “VgChart” and check the mounting state. If the mounting is unstable, the AMF index
cannot be improved no matter how many times the adjustment by ACP is performed.
Please check the cause of the problem referring to the analysis result, and perform adjustment
again.

main scan camera, please
make sure to perform scale

Feedback
When the AMF Index value falls below 1.0, the initial
adjustments of the items adjusted for the main camera (Fiducial
camera scale, Head offset) are not basically performed.
The value of “Index 2” varies depends on
the patterns of the mounting results data. If
the value is 1.0 or above, please perform
feedback for the correction value instead of
performing adjustments such as scale
adjustment.

6.2. Check the “VgChart”
1. Click on the [VgChart] button.
The chart screen is automatically created based on the measured data by clicking on the
[VgChart] button.
Figure 53
2. Check the Chart screen
Check the Chart screen to determine which head is the causal factor that the “AMF Index 1”
does not meet the specified value.
Figure 54
Analyze the chart and perform further adjustment if needed.

6.3 How to analyze the “VgChart”
Please refer to the following for the typical chart of the adjustment result and how to take
measures.
A. If the XY offset shift is found in the data of mounting result
What is “XY offset shift”?
When the deviation is found in the positions where all the components are mounted, in the same
direction and in all the angles as can be seen in Figure 55
.
If the analysis result by the Vg Chart indicates that there is “XY offset shift”, perform feedback for
the compensation value of the measured result.
Figure 55
1. Check and save the corrected value
1) Select the “Accuracy Value” tab.
Click on the “Accuracy value” tab to display the screen shown in Figure 56.
Figure 56
2) Check the values to be corrected.
Check if there is no problem with the values to be corrected, then click on the [Save
Mch.Data] button.
2. 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”.
