Hi Anthony,
I'm about the same place you are, learning to make PCBs using the
toner transfer method. I went to a local chain of paper stores
called The Paper Zone and got samples of numerous types and weights
of clay coated paper and ran numerous trials. I have settled on the
gloss coated 80# paper shown in the link below:
http://www.paperzonestore.com/cgi-bin/paperzon/WEGW1180.htmlIt seems to work pretty reliably although I'm still using pretty wide
traces (25 mils) while I work on my technique. After soaking and
brushing off the paper, the toner traces are a light gray because of
the clay attached to it. I don't try to remove this since it doesn't
seem to cause any problems. I have been preparing my boards by wet
sanding them with 400 grit paper and then cleaning with Acetone and
this seems pretty good. I'm thinking that my next purchase may be a
laminator. I'm using an iron currently but find this to be not as
consistent as I would like. I liked the note from a user recently
who was using a Royal Sovereign laminator and would like to hear from
more users with their laminator experiences. Is anyone using the
laminator which Pulsar sells specifically for PCB transfer?
Thanks to others on the board for all I've learned.
