Does anyone have experience with placing heat sinks on BGAs? I have limited experience with PSA (pressure sensitive adhesives)heat sinks, and am interested with the possibility of a clip-on device. I am specifically concerned with ease of assembly

Is there any difference in performance when running paper tape or plastic? What's the smallest passive component that you have fed in the feeder? How does pressure sensitive adhesive (PSA) tape perform in the feeder? PSA has a tendency to transfer

We have an application where we are applying a heatsink with a thermal tape that has pressure sensitive adhesive (psa) on either side. Does anyone know of an off-the-shelf heatsink press that we could use to apply a consistent, measured force for a

PSA - Pressure Sensitive Adhesive? I don't know which type of tape the affected reels of parts use but it is not sticky. Thanks everyone for the comments and suggestions. There were no missing teeth on the plastic take-up reels. I have cleaned an

Sounds like PSA cover tape. Contact Siemens about this. There may be an adjustment or modification to the feeder to stop it from delaminating the tape. This is generally a problem in feeders that have continuos tension on the take up mechanism (su

Yes Davef, storage condition and long time remaining on shelf could effect pealing strength, but we experimented that by using Polystirene Carrier Tape also this problem was reduced almost to zero. Df, If I am not wrong when you talk about pr

It read to .0001 and was repeatable to +/- .0005. As the SR coating got thicker, it was more sensitive to pressure since the transducer (ours was a 1/8" dia.) would press into the coating. You might request a demo from a vendor and see if it is a f

We had this issue with a few parts on our universal 8mm feeders. The set up was correct all mechanisms were working, even tried a new feeder. The spring in between the take up wheel and pick point just wasnt cutting it since the adheasion was too m

Is anyone having trouble with PSA (pressure sensitive adhesive) cover tape used with embossed plastic tape? I am placing 0402 components out of embossed plastic tape with PSA cover tape. The feeders gum up, the take up reels are impossible to remov
