Hi Markus
I ran across a site that looks well suited for this thread and the
Inkjet printing thread..
http://www.rtcircuits.com/They have a couple of patented methods of making (really) printed
circuits. The first, they are just printing using conductive ink. The
second, and maybe more interesting from your standpoint, they print a
resistive image of the circuit on a substrate and then plate it. They
claim to get circuit widths that are small:
"And Track Widths down to 20 microns are easy to produce." I really
like that you are not producing waste copper with this method. I wonder
if their ink is stampable? How resistive is Indian ink, does anyone
know (Indian ink is pretty much ground carbon and water, isn't it?).
Is you can see from this post, I'm coming to the realization that some
type of chemical process will have to occur for me to make pcbs. ;)
(unless I can get the multilayer laser printing thing going).
Slap me on the forehead! Didn't someone say some types of toner are
conductive? Does anyone know which ones? I wonder if they are
conductive enough to copper plate? Print the circuit on bare FR-4 in a
laser printer, and then plate it on. Has anyone tried that before? Is
anyone with a thp system interested? At this stage, the most I can do
is root you on and throw out ideas.
Thanks,
Richard
