The plastic must be anti-static otherwise you can charge up your parts as
they pass the plastic, causing you much trouble.

Peter,


My understanding is that most feeders pull the tape back at some distance
before and travels under a shudder plate until the component pick-up point.
If your feeders have a big enough opening where the tape is pulled back, try
placing a piece of plastic to close that opening so that it leaves enough
room for just the tape. This way, the plastic will impede the progress of
the component,and in turn, will fall back into the pocket.

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?
