SMT reels using paper for caps and have problems with feeder jam

5v or 12v feeders.....and are you sure the parts fit through the feeders and are not getting jammed. On some of the old feeders you had to remove the springs and other parts to make the tall caps work.... chow

Is anyone aware of the spec for tape if any?

Thanks for the spec Greg, For us it is the stiffness.

I agree the stiffness is definately the problem.

I wouldn't say we've escaped either - Fuji blade wear is heavily up at the moment.

Yes I would have to agree Kemet is the worse. I believe our feeders are just not strong enough to handle the thickness of the tape. It seems to need alot of force to move and to roll the tape through.

Does anyone else encounter problems using feeders to handle caps that are reeled up with paper tape. We are having alot of problems with vendors that are now using the thicker type (like cardboard) to use to reel up caps. Our feeders either run too

EIA-481-B Max tape thickness 1.1mm (not including bottom and top cover tapes which can be .1mm max each) Of course a 1.1mm thick piece of steel will be stiffer than a 1.1mm thick lasagna noodle (already cooked). Is the thickness the issue or is it t

We are also experiencing problems with this thick stiff paper tape. Our problem is the strength of the spring that supports the tape at its pick position. After a while it just pushes it down because the tape exit wants to bend the tape too sharply
