<< I'm having a problem with one 0805 cap part number where the parts are
being pulled out of the pocket before the placement head can pick it up and
they are sticking to the cover tape as it is pulled back from the pick up
position.
I have tried another reel and still the same problem. I'm guessing it is a
static charge that is being generated that is causing this. Don't think it
is glue. I have another 0805 cap in a feeder right next to this one and it
is not having this problem.
This is a consignment build with the customer supplying us with only two
reels.
Any ideas?

Hi Peter!
It could be the cover tape...the cover tape could be a P.S.A. (Pressure
Sensitive Adhesive) tape. It normally doesn't happen because a cap usually
sits in it's pocket low enough so that the tape won't contact it. BUT, if the
cap is pretty thick and maybe in the wrong sized carrier tape (not deep
enough pockets), it may sit high enough in the pocket to contact the tape,
and if it's a PSA tape I could see how that might happen...
