Etching deity 1, Stephen 0 Etched PCB fail. The copper was eroded under the etch-resist ink. So there is not much left. Perhaps left too long, but also there is still copper between the pads in places where there was no ink. I will make sure the copper is thoroughly cleaned before I apply the etch resist. I might even go something a bit more heavy duty than the etch resist pen. Nail polish?
