I was wondering if anyone has tried using a pantograph for making a pcb. A larger scale image could be printed out on paper and traced using the pantograph to make a smaller size on the pcb. A fine tip magic marker could be used as a resist or maybe just printing directly using conductive ink. It is sort of a low tech way to do it, but it would provide another option.

That is an interesting thought. I happen to have an old Hermes engraving pantograph with a diamond tip. I could print the PCB out 2:1 and trace the spaces between lines to scratch the copper through to the substrate, which would isolate all the copper that I want to keep. As an alternative I could spray paint the copper and scratch off the paint where I want to remove the copper, followed by etching the copper in the scratches. I have used this technique before, but used an exacto knife or carbide scribe to hand scratch the paint off instead of a pantograph. I will have to try it and see what happens. It should work for fairly small boards in any case. Bob [Non-text portions of this message have been removed]

that'd certainly make it easier to do fine detail for those preposterously tiny smd pads... templates could routed in wood/plastic/cardboard with cnc equipment that doesn't have such fine detail, like a carveright, cricut, makerbot -- Riley On Sep 7, 2011, at 9:45 PM, "javaguy11111" <javaguy11111@...> wrote: I was wondering if anyone has tried using a pantograph for making a pcb.

I think it would be significantly easier than making one by hand, significantly harder than making one via some fully automated process PG

Hi I have a small engraving pantograph for marking signs. Copied a trace from paper, It turned out fairly rough and is Ok for a small board without IC. This is an exercise of great care, one slip and bingo! Start a gain. Regards Tim I was wondering if anyone has tried using a pantograph for making a pcb. A larger scale image could be printed out on paper and traced using the pantograph to make a smaller size on the pcb. A fine tip magic marker could be used as a resist or maybe just printing directly using conductive ink. It is sort of a low tech way to do it, but it would provide another option.
