Did you teach the reject mark? Sounds like a lighting issue when looking for the white sticker. You can also skip images by pressing control-repeat after the machine has found fiducials. Good luck

Hi all. I used a 5/16" white paper sticker to mark a reject PCB in a panel of 10. One of my my Quad 4Cs sees it O.K. and marks the PCBs reject. The other machine either shows them all reject or shows the marked one as good and the other 9 as rejec

Are there recommended image reject marks in order to process x-outs from a PCB supplier? Do they have to be in the copper or will silkscreen suffice?

You're not the only one. We just got done with a batch of ICs that had a high reject rate at placement. The machine was rejecting about 70% of the parts because it didn't recognize the part. The reason it didn't recognize the part was due to the f
