I have a problem setting up the LAE on my Quad 4c. I set it up for 0805, and it seems to work, although it rejects a lot of parts, at least it places "most" of them. I tried setting up on a soic14, and could not get even one to pass. I believe I h

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

I place 0302's on my Quad 4c's all the time. Use a repeat pick-up just like a waffle tray part but make sure the z height is perfect on your pick-up or you will bounce the other parts out of their pockets. Also change your mod code to only try once o

Quad IV C Recommendations

0603 and up should be no problem on the machine. If you are doing under 25 mil pitch the machine needs an upward camera to repeatably place the parts. You will always lose the first 10 or so parts with cut tape but that should be about it. Repair par
