Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

I was playing around with some scrap pieces of circuit board I etched and
drilled in order to find a way to simulate the HASL (Hot Air Solder
Leveling) process. This process puts down a very thin coat of solder over
the copper. The solder protects the copper plus makes soldering in
components easier.



I found that I could brush the board with flux. Then I built up a small bump
of solder on the ground plane. Using my soldering iron as a paint brush, I
dipped into the bump and then painted the copper. When done, I scrubbed the
board with alcohol. Worked great. I had no shorted paths.
