*Subject: **Re: [TN] Most  UV Resistant (conformal) coating?*


without knowing what is your application for UV intensity, as doug said,
hard to select.  If just the UV you are worry about, you can use $$ - PTFE
might be your best bet if money is not issue...

Application is key: to prevent IC - a bit thicker molding compound would
work (UV erasable type), even just a good piece of tape.  it either
protected by UV blocking (molding compound) or UV reflecting (mirror like
coating).  Exposure time, intensity also matters as well as type of UV - A,
B, or C.  with presence of other lights.  IMHO.
Good luck.

Anyone have a clue as to what  type of coating that would be?
