I've done 3 PCBs drawing the traces with a permanent ink pen. But the Ferric Clorhidre always attacks partilly the traces, so they are not shiny, and it's a pain to solder on it (alos, some traces are partially damaged).
It still works, but now I want to do a more complex project and I need to do better.
I use a Stadtler Lumocolor 0,4 pen. And here¡s the strange thing.. I also used for my last PCB a Stadtler Lumocolor (same as the other, but 0,8), and all the traces and pads done with it, were shiny and almost perfect!
So, I supose is not my fault, and that I use a not good pen for this. Any recomentdation?? Thanks!!
