 Good information. I have tried many times to get thermal transfer to work with a Brother printer, but it seems the toner just does not want to melt like some other printers apparently do. I will try laquer thinner next time I make a board. I did see a post that pre-etching the board a few seconds helps with adhesion.

       (pure) = shortcut notation that I did not modify it
 by adding anything else. It is "acetone" (bought
 in Homedepot paint department. It is not "nail polish
 remover" which most likely contains acetone but my also
 have other stuff in it.
 I printed some text
 on a sheet of paper using the Brothers printer. I then
 deposited (in different spots) acetone, Isopropal alcohol,
 Methal alcohol, MEK, Naptha, and Laquer thinner. At each
 spot, I put a blank piece of paper and held it for about a
 minute. The Laquer thinner location was the only spot in
 which there was actually a transfer of print on to the blank
 paper. 
 
 I didn't
 perform any other test because I'm busy with other stuff
 right now and I'm not experienced in using the chemical
 transfer process. That is why I suggested that someone
 already doing chemical transfer (and having a Brothers
 printer) give this a try on PCB and tell us the results. I
 have no idea how well this  transfer would stick to PCB for
 etching.
