I have been reading all the articles concerning the etching of circuit
boards, something I have a great need to do.  And they all assume that
one would be etching the copper off of the board.  Is it possible for
the home hobbyist to devise a system to deposit copper onto blank
boards?

I would picture a system where the hobbyist would pre-drill a blank
board, then treat it with a photo-sensitive material.  After the
photo-sensitive material has been applied both sides of the board
would be exposed.  The exposed images would then be developed most
likely in a chemical process.

After the circuit images have been developed the board would then be
treated either chemically or electrically to bond copper to the traces
developed on the board.  The might solve the problem of plated through
holes as they might get coated also.

I remember years ago someone describing a system similiar to this.
But I do not remeber if it dealt with circuit boards.  It may very
well have been used on something totally different not even related to
electronics.

If anyone knows of a process similiar to this I would sure like to
hear about it.  I picture the process would be much more precise then
etching, one would not have to worry about the etchant cutting under
the traces, etc.

I'm trying to do digital circuits and am getting ready to purchase
some TEC-200 paper to experiment with.  But I don't think it's gonna
be easy to do double sided boards or keep the traces as small as I
need them.

Thanks for any info.
