I have PCBs with SMT nuts (SMTSO2060MTJ) which has been assembled onto a PCB – the nut has kapton tape on top to allow easy pickup for assembly. 
However, removing the kapton post reflow is proving very time consuming. We have a few thousand to remove. Currently, we are using a pointy edge of a needlenose tweezer, and a kind of angled stabbing motion to spear the tape – when this works, it allows perhaps 20 to be removed before needing to remove the tapes from the tweezers. However, it's not fast. We have also tried a modified "fishhook" barb but this ripped the kapton and it wouldn't come off in one piece.
How can we do this faster/what's a better method? I have wondered if we might be able to blow them off with compressed air from the back side but the tape is quite sticky.

After much trial and error the fastest method we have found involves poking the kapton with a rod from the back (which loosens it but doens't remove it completely), and then using tape to remove - either of these in isolation doesn't work but combined the method is pretty quick and can remove several thousand per hour when using a jig.
