I have been following the PCB thread with a great deal of interest, as I'm
sure many others have.  I was perusing back issues of Circuit Cellar Ink
(all of you *DO* subscribe to this wonderful journal, don't you?) and came
across the following.  Though I have not tried it, it sounds very
promising.

The article is on page 80 of the August/September 1992 issue (issue #28).
The article is by Jeff Bachiochi and is about a product called the Toner
Transfer System by DynaArt Designs.  It is a paper that is specially coated
to allow easier direct-toner transfers of artwork to PCBs.  The way it
works is that you print out your artwork and iron it on to the PCB, as in
other designs, but then, and this is the secret, you put the board, still
attached to the paper, in a tray of water.  The water dissolves the
"special sauce" that lies between the toner and the paper.  Like a decal,
the paper lifts off, leaving the toner on the board.

Again, I have not tried this myself, but the author of the article is very
enthusiastic.  He claims he had no problems using this technique in making
a double-sided PCB.  The paper comes in 8.5 by 11 inches.  The author does
not mention how many sheets in a box nor the cost of the system.

The address of the manufacturer is:

        DynaArt Designs
        3535 Stillmeadow Ln.
        Lancaster, CA 93536
        (805) 943-4746

        Toner Transfer System #TTS 58511-392

Again, this article was published in 1992, so I don't know if this is still
available or not.  I'm not ready to etch a board yet, so I didn't call to
find out, but I thought this might interest some of you.

Please let the rest of us know what you find out.
