What are the negative, and positive (if any) considerations for removing or
leaving flux deposits on the circuit board after soldering?
Thank you.

I am probably not qualified to answer that question on a loaded board. The
suggestion was just for home brew type cards. In the type of work I did, it
never seemed to make much of a difference if the flux was cleaned or not.
Though we did it for cosmetic reasons. As for a bare industrial board, they
use a piece of equipment called a Sirometer to measure surface insulation
resistance that will vary according to contaminants left on the board. The
board is immersed into a 75/25 mixture of alcohol and water with a couple of
resin filters. Dependant on remaining contaminants, the SIR readings will
show in spec or not. There's a lot of info on Google on such devices, so I
won't drone on here. The piece of equipment I seem to remember is an
Omegameter. Hope this was of some help...if not....the price was
right!....Ross
