Subject: [TN] Conformal Coating


Dear Technet Experts,

I am in need of info on conformal coatings.  We are contemplating coating a
4-layer board (signal,vcc,gnd,signal), .062 FR4 2 oz all layers, smobc.
It's 100% thru-hole.  The board carries about 2.5 amps.  The board is placed
in a commercial electric grill where contaminates such as grease and (ugh!)
bugs are common.  Is there a web site of reliable tutorial info on types of
coatings, advantages/disadvantages, etc.  I've found a couple of commercial
sites, but need more objective info.  Any help is much appreciated.
