Hi, its unfortunately not that simple. Essentially if you add chemicals
to the paste you muck up the rheology, or the die itself may cause
spitting and so on. Some resins do fluoresce under UV, so you might like
to try without doing anything.

If after that you are still looking for a florescent paste contact me
off line, [we have developed one especially for just this sort of
thing].

Subject: [TN] fluorescing agents


Does anyone know of a liquid fluorescing agent that I can blend in with
some no -clean rosin fluxes and solder pastes? I'm trying to do some
qualitative cleaning tests under low standoff SMT components.

Thanks
