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

Table 27
* If the head offset does not meet the specified value, it affects the vacuuming and mounting
accuracy. The possible causes are distortion of the shaft, the improper installation of the nozzle,
and so on. Please take the relevant measures.
