Coincidence: I saw in a trade journal today that Epsom have been experimenting with conductive printing ink & have made a *fourteen layer* :shock: pcb, with alternating insulating ink layers!!
I hate to think how much a cc of THAT ink will cost :x
I think I'll still be using stripboard for a while yet.. I can imagine conductive printed PCBs being great for high impedance SMT work, though.
I wonder if it is possible to get powdered metal to stick to a photocopied trace on paper or cardboard? If you had metal powder spread on a surface, and put a photocopy or laser print face down & ironed hot enough to melt the toner, then the metal powder would stick to it!
Hope nobody has patented that! GO FOR IT :lol: MAD SCIENTISTS
hint: think nickel powder, most other metals have oxides on their surfaces or other problems.
