PCB Manufacture – Part 3

So just did a full board with the new UV lightbox, and it came out pretty good. Need to do something better with the sodium hydroxide, but other than that a success.

the finished panel

The board has a few places where the photo resist failed, mainly due to how long i had to develop it for, and using a sponge probably didn’t help. So for next time, no sponge, and heat the developer up a bit beforehand… its a bit cold in the garage afterall.
