1. Check the values of “INDEX (Total)”
Display the “Result 1” and check the values in the “INDEX 1 (Total)” and “INDEX2 (Total)”. If
the values fall below 1.000, the fields turn red and the lowest Index value of each head is
indicated by boldface. Please check the recognition state and the cause of the problem on the
“VgChart” screen and perform adjustment.

machine
8.1.How to perform scale adjustment of the fiducial camera
Adjust the camera scale by using the marks on the board as the conventional method.
When the machine is equipped with the sub fiducial camera (Option), perform adjustment for
the both fiducial cameras. Table 25 shows the specified values.
Items to be adjusted Specified value
Scale XY 10.000 - 10.600
Camera Angle 0.000 +- 0.500 degrees
Table 25
Click on the [Fiducial Camera] button on the main screen of the CalibSm.

Please follow the same procedure as the scale adjustment of the scan camera.
There should not be much difference between the measured value and the current value.
8.4. How to adjust “Head Offset XY”
The adjustment of the Head Offset XY is performed with the main camera (Scan camera).
(It is also possible to perform adjustment with the multi camera by logging in as “Engineer”.)
[Tools required for adjustment]
- Nozzle to be used: Type 303A (314A) nozzle (For SOP)
- Component to be used: Glass QFP 16pin (with white sticker) (KHY-M880A-00)
- Part No.: No.34 QFP16_P0.8_WHITE (Board data: MCH_SETUP)
[Procedure for adjustment]
Click on the [Head Offset] button on the main screen of the CalibSm.
Select “Head Offset XY” from the “Adjust Item”.
Make the nozzle vacuum the Glass QFP 16pin (with white sticker on the back) to perform
adjustment.
The number of the head to be adjusted at the same time is limited depends how many Glass
QFPs are prepared.
