The calibration was ok. When i switch off the back camera and use front one everything is ok. Is it true that when Topaz use back line camera after checking the components the machine rotates the components 180 degree?. Mark \

Hi! Try to make "R_AXIS_ACCURACY" calibration for all of FNC heads for back camera only. I met such problem on Topaz-X. There was clearly seen offset on 0.8mm pitch components. I simply calibrated all cameras for FNC nozzles and problem disappeared.

I would run scale calibration first (for the suspect camera). That may be your only problem. However, if your having a rotation issue and all major angles are off (differently) then it is most likely R-axis accuracy. However, I would run AMF and

Oooo, you are waving 0402. Tell us more about your wave and its set-up. Never seen this [knock on wood]. When is this skewing occurring, after placement or during cure? What�s the distribution? What happens when you slow-down yer placement rate?

Is the glue intended for printed SMD attach? 3 Are you following all the manufacturer�s glue shelf life recommendations? 4 Are you observing all the manufacturer�s glue working life guidelines? Finally, what level of skewing are we talking about?

Hi guys I am having problems with skewed placement of 0402 devices I would like to add the board has raised pads and we are placing on glue. We are now printing the glue rather that dispensing with a GL5. have any of you guys had this pro
