I've seen problems where the component was slightly thicker than the tape and popped out of the pocket upon transport. Is the component still in the pocket after mispick? Do you have access to a high speed camera or could rent one for a day?

We have struggled with this as well. Basically, we have a consistent rotation for all packages of the same type, but I don't think our rotation has anything to do with the actual rotation that the PnP equipment actually wants to see. I believe our
