Hi there
I have made a couple of PC boards like I normally do, but this time they were awful. The etch solution etched the already etched traces and made large holes in it. I think it's because I normally just do smaller board under 10x10cm, but now it's a 16x10cm. What can I do to avoid this? More UV, more developing, hotter etch solution...?
