Hi Liza - polystirene monolayer (blend ?) could be sealed at less presure, ie 35-40 PSI. Temprature could be 165�-170�C. For sure after sealed you shoud make sure the sealing strength (peel strength)should meet min 15-25 N.(bet avg from 25 to 45 N)

A quick and dirty test; Take a few inches of carrier tape, peel off the cover, gently turn it upside down and see if any of the parts stay in the tape. If they do, then you know there's an issue with the tape.

Apparently the adhesive tape peels off from the joint, which could have some reasons. 1. There should be an overlap of the cover tape, as Cal mentioned. The new cover tape laying over the old by approx. 2mm. I also peel the cover tape a bit off, whi

This happens with either old tape, the cover tape doesn't stay sealed on the left side, or is the seal is too far to the right, the knife lifts the cover tape. There isn't much you can do in this case. Your choices are: switch the component into an A

Does anyone else have issues of certain cover tape that gets stuck in and around the feeders? I have been fighting these 2 tapes all day. I try to tape them to the pocket tape with a twist, but it only works so long. It happens Either because its s

Bert, The original IP feeders do a poor job of peeling the cover tape. Things to check: -All teeth present on the take-up reel -Take-up reel has even drag as it rotates (reel out of round or dirty) -Take-up reel drag is not too high (locations and

Does this only happen with certain feeders or certain components? We have a few regularly used components that experience the same problem ( Philips SMT machinery ) where the cover tape is just too sticky. Experience taught us which components will c

Hi, Does anyone have problems with the cover tape not peeling back on the 8mm wide feeders. We often find that particularly at the start of the job, the cover tape doesn't peel back causing mis-picks. Thanks, Grant

We all seem to have forgotten about cover tape peel force testers. GPD makes them as do others I suppose. I would ask the tape and reel house if they have a tester. If they don't I would consider using someone else. Otherwise as another poster s

I beg you pardon AR, I made a mistake by reading your request, you are looking for a service lab who can do the peel back force test and not the Reference Standard (like EIA-481) for T&R. You should check if in your Country some Tape and Reeling Serv
