stripping pcb traces?
Ferric Cloride
Clean off the solder-resist screen (stuff coveting the runners) with
solvent, go over with fine steel wool, dip in PCB etching liquid for about
15 mins, (available at any electronics store, includin' ****Shack), wash
with soap & water - Presto. Individual runners 9post-engineering f8ckups)
could be sliced through with an exacto 9tm) knife, and then you can pull
off
the offending runner, or simply take out a 3 mm section of it (make two
slices) to cut. Easier to buy a cheap-o PCB (they're cheap, and the
etching
stuff 9forgot the chem name) is cheap if you buy a gallon).
There are many sites on the net which take you through making your first
PC board, and many companies now offering short runs of your design. Some
even provide layout software. Have fun. I personally hate PCB's, but
there's little doubt that they're the easiest & best way of daling with
small-signal stuff. Look at some older & RF pc layouts, that's how I
learned. Use your printer & transparencies to line up both sides &
instantly see the errors, or do one side in red & one side in black &
print
out one over the other. Make sure you make corner hash marks. 'Luck.
