So, as I thought, there are a few issues but overall (and especially for home etched PCBs) I’m super impressed by the results! I think I’ll widen the lines and gaps a bit, plus I’ll clean the board before UV printing next time.
I’ve had this idea for a good while now, and I’m excited about how it’s gone so far. I don’t know why I have such an issue with mechanical switches, but I’m always looking for an alternative. Anyway, I printed this mask on a copper board at lunch, and I’ll etch it later tonight when I have some spare time. It has a few problems, but will be a good proof of concept:
