Homebrew PCBs

What a small world... I worked once for a gentleman who was a boss of 
Dennis before he became famous. I remember that it was a kitchen 
table with all relatives helping out and Dennis was told that he 
would not sell more than a few dozens of modems because who in the 
right mind would want to connect computers to each other! Dennis was 
at the time a technician. Great success overnight, cash paid 
building, lawsuit for an &AT key string, divorce and out. I guess his 
patent has expired.

That electrochemical method of cleaning makes a mlot of sense to me: 
I have seen it at the galavnizing (plating) shop many moons ago. The 
guy dunk my part into the tank (part was connected to the circuit) 
for cleaning and seconds later he was plating. I was always puzzled 
what that process was and meant to ask that question yesterday. Great 
that you commented on it. That process of cleaning does work. Now, I 
am not sure what hte electrolyte was, but chances are pretty high 
this is it. Glad you mentioned it, Adam.
