- 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.
