Hello, I use Siemens MS128 & HS180. I need to place a lot of TO-252AA, SOT223, ... components. At the moment I use only mechanical centering but I want to center these components opticaly. There is no problem to center chips and other symetrical com

Another sticky issue is that if you use after market nozzles especially mixed in with Fuji nozzles the Anti-Marking Illumination Disks can be different enough that the vision system will reject nozzles. Jerry

I've had some that under normal light they looked the same but when the UV light hit them they were very different.

The right paper incorrectly applied can be a problem also. I have seen it on even new Fuji nozzles with the illumination disk bunched up on one side of the tube with a gap on the opposite side.

Hi all, Is it normal for some of the small nozzles to be rejected by the wide view camera? Every time I do a nozzle centering the narrow view camera shows green circles for nozzles 1,2,3,4. The larger ones (5 and 6) show the asterisk. The wide view c

The nozzles get centered at zero degrees and 180 degrees. I believe the yellow asterisk is the measurement at zero degrees, when it rotates to 180 is when you will get a red X or a green O. (In other words the yellow asterisk is normal) I think you

Thank to all for the help. The problem was the reflective disk. They're all green now. Thanks again. I got another error but I'll start a new thread because it is not related to the disks.

The centering jaws are made out of copper, I believe...and conductive. I'd suggest that the conductivity of the copper makes it a fairly poor source of ESD damage in a component. I have observed physical damage to components from the centering jaws

We have placed billions of components with our Mydata's. No issues with ESD.
