  • Building Sproggy's PSU, PCB question....

    Okay, I've begun to assemble the PSU from sproggy, but I'm having a problem getting the etch-resist done properly. It's coming up all streaky and broken up.

    That said, I'd like suggestions from those who have made Sproggy's PSU on exactly how to get the board created.

    Although I cannot help you here (haven't done it yet, but I want to) I would be interested in know exactly what people are buying and using in order to do these PCBs, as I have never done one before

      Okay! I just tried a new tranfer, and patched up what needed with a rub-on etch resist kit, and gave it the etch treatment... looks like it came out good!

      Now, I just have to find a drill bit small enough for this... What sizes are recommended?

      And to Telek: What I used was a standard Copper-Clad Board (available lots of places, inc. RatShack), a rub-on etching kit (came with rub-ons and etchant), and some stuff called Press-N-Peel Blue, which I printed (on a high-quality laser printer (at least 600dpi is recommended)) sproggy's design on. You then take a standard iron, and iron on the design. (I had to make a fair ammount of patching, but not too bad).
