Really, the method works (with a laminator). I'm familliar with the
photo-resist method and have the equipment and have used it in the
past. I don't use photoresist now because toner transfer works great
for me. Once you get it figured out it is actually faster. I can do
everything I want with less expensive materials. I've done stuff
quite a bit more complex than what I've published on the website; but
I thought the given examples were sufficient to prove you can do
pretty fine pitch work with the method. There still seem to be some
critics out there. Thats fine; but don't discount something just
because you haven't had as good of results yet.
I've just done (last month) a 188 processor board with 2 100 pin
tqfp's, 1 32pin tsop,1 40 pin pdip, 1 28 pin SOIC, 1 24 pin SOIC,
several headers, leds, resistors, caps, SOT-223's. This one was
tight and a bit of a headache, but more from drilling and soldering
that many holes (>100). Thats mostly because I used a $39 harbor
freight drill press.
Maybe I'll have to post more pictures...
Anyway, photoresist works. Toner transfer also works. Both take a
little bit of experimentation to get workable results. My first
photoresist boards weren't exposed/developed perfectly, just as my
first toner tranfer boards weren't perfect either. A little patience
and practice fixed that for me. I'm sure it could for you as well.
