Cleaning/Recovering a soaked and corroded PCB

2003-01-15 by ghidera2000 <ghidera2000@yahoo.com>

I have a 24vac timer that got soaked pretty good. Tons of corrosion 
on the resistors, diodes etc. The four ICs also have smooth glassy 
looking areas over some of the pins (power pins I bet), making me 
think they're fried.

The traces look good though. The dielectric seems to have held up, no 
evidence of burning etc. Just for the hell of it, I'm going to see if 
I can clean this up and replace the ICs to see if I can get it 
working again.

Question is, Whats a good method of drying out the board after 
cleaning? I'll go at it with distilled water and a soft brush, then 
some contact cleaner but I'm worried about water trapped in little 
nooks and crannies.

Would putting it in an oven set for, say, 200F for a couple hours be 
a good way? If not, what would?
