How to attach a paper screen to a DIY PCB?
Paper can have a pretty low resistivity value if the relative humidity is higher. I read somewhere that it changes downward by a factor of 1000 going from about 20% to 60%, for example. Still may not be any problem. But since you are worrying about the glue, I thought I'd throw that in just to give you something more to worry about.



You would want an "electrically resistant" epoxy or adhesive. For oddball electronics situations like this, one place I consider is Cotronics Corp. I use their products already and they are good stuff to have around, at times. In this particular case, you might consider their Electrically Resistant Epoxies or their Electrically Resistant Ceramic Adhesives. If I were buying, I'd probably would try out the first link to start, though I'd be curious about how well those from the second link might also work.

You should consider contacting them directly to ask. Chances are, they can recommend something more specific.
