The bubble inside BGA ball locate at via in pad and apply the resin plug hole.You shall check the cooper plating quality on PCB pad. If there is thin plating or broken on the pad then air will come from the resin plugged via and be trapped inside the

Deni, Thank you so much for your reply. Does this Calibration procedure require the calibration plate? Is there anyway to fix our calibration issue without it?

Yes, to calibrate you need calibration plate and calibration "parts". There's something you can try, though. There is a setting for on-head camera position. You can modify these values (write down original values, of course) manually and then try it

Why don't you try to manual trimming. If I remember, you have option to trim by camera or by head. This is only for FlexJet (7-Spindle)head.

Sorry for mis-information, it was a long time ago since I fiddled with that data. Default positions are only used for calibration, which then generated actual mapping files. So, it won't work that way...
