I just ran up a few boards last weekend. I've had a
great success with the Staples inkjet paper, but based
on the recent discussions, and the fact I had some
extra time, I decided to try a few other papers and
techniques.
I am using a Samsung ML-2010 with third party refill
toner and a Xerox laminator.
Paper: the best and most amazing result was with the
paper from the SEARS flyer in the sunday paper! Great
transfer and almsot fell off under hot water.
Fusing the toner: after removing the paper and before
etching, I flash fused the toner using a hair dryer. I
flash fused half of a test board. The flash fused
portion has excellent 0.006" traces, where the
"normal" 0.006" traces were very crappy and had gaps.
Etching: I used a Muriatic Acid / H2O2 etch. 3 parts
water, 2 parts Muriatic Acid and 1 part 40 volume
H2O2. It gave a etching time of about 3 minutes. A
little quick, next time I'll reduce the H2O2 a bit.
"Tinning": Well not actually "tinning" per say more
like protecting the traces from oxidation. I had read
about using Future floor wax as a resist. And yes it
does work. This time I wiped a thin coat on the trace
side after etching and let it dry. Soldering was no
problem.
Just a few more tweaks to the Toner Tranfer process.
