Laser toner transfer - IT WORKS

2003-10-27 by wheedal99

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.
