Peel Back Force | 25 August, 2010

We've been breaking the cover tape on components from a specific supplier. I am curious what the standard is for the peel back force range, so I can better know if it is a feeder issue or component supplier. Of course the machine vendor is blaming the tape and the component supplier is blaming the tape feeders.

Thanks!

You may want to search on "Cover Tape", what date code is on the parts reel? I have multiple issues with cover tape sticking to the paper and not peeling back. Causes pick errors due to the part being covered. I think my problem is the parts have too much shelf life 2005,2006 on lots of them.

I previously did a search on "peel back force" and there were a few results, and there were a few hits that say EIA-481 is the standard, but nothing on what the standard force range is. A search on "cover tape" yeilds many hits about breaking cover tapes, but agian nothing (that I saw on how much force the feeders should be pulling the cover tape with.

EIA-481 Section 4.11 gives the min and max forces, but the values are based on the width of the reel. 0.1 - 1.0N (10 - 100 grams): 8mm wide 0.1 - 1.3N (10 - 130 grams): 12 - 56 mm wide 0.1 - 1.5N (10 - 150 grams): 72mm and wider Peel force to be measured at a peel speed of 300mm/min.

Hey, great, thanks!

Now I can check with my machine maker and see what their feeders are spec'd to.

I may send a reel of parts out to be tested, too.
