Currently sat in my garage, waiting for a UV photo resist board to be exposed – trying it at 8 minutes. This is after our first forray into UV pcb’s, where we didn’t expose it for long at all… and it didn’t work. Well, it did, after we put it in an even higher strength sodium hydroxide solution…. around maybe 7% or so… and proceeded to eat all the resist off. Will post to say how well this one goes…
