Rich, I seen the same demo by 3M. They make a anti-static Kapton Tape (#42) that generates virtually no charge on either the peel-off from the roll, or the peel-off from the board. The tape is about (?) 50% in cost however, but this may be peanuts compared to the cost of ESD failures. The advantage of the #42 tape over the ionizer blowers is that the tape is fool-proof. With the blower, the tape has to be put on and pulled off in front of the blower (hopefully working properly). If the tech from test borrows a roll of tape to hold down a jumper wire (and you know he will), he won't be in front of an ionizer. Again, with the #42 tape, who cares. Also, data I've seen show that the #42 tape leaves equal or less residue on the board than its non-conductive counterpart. Other alternatives: titanium stiffeners; G10 goldfinger protectors (Stevens Products in New Jersey in almost any size); or wave solder fixtures to mask the goldfingers.

Does anyone else have any experience with Kapton tape and ESD concerns? What are the alternatives? Any historical problems with Kapton and ESD? We typically use the Kapton for masking gold fingers. Any help is appreciated.
