Homebrew PCBs

Hi Bernie.

Yes, it's exactly what you understood... I apply the iron on the paper
while it is wet with alcohol. It's not to soak or drench it, just
enough so it'll stick to the copper while letting you see the tracks.
If you use too much, you'll smudge the toner on the copper... I have a
pic about this:

There are two possible mistakes here (this was one of my first trial boards):
1) Smudging of the tonner due to excessive use of alcohol (center of
the board, a bit to the left)
2) Not enough pressure (the area with no tonner in the center of the
board and in bottom right area)

Anything else, just say it!
