#3 with off-board LED wiring

to clarify when using diagram #3, the LED and SW on the board will be empty?

Hey all,

So I just etched my first boards ever, two quasars and two egodriverrs and they came out pretty good. But I think I mightve left them on too long because they are starting to oxidize a little it looks like. I want to tin them but can't figure out a good process with the resources I currently have. It took almost 35minutes, maybe it was too cold or i wasn't agitating enough.

If I just use some rosin core paste flux and trace the traces and then a little bit of heat and solder, would that work well? Or do I need to get liquid flux with non-flux solder and spread across the whole board??

Thanks a bunch!

cool thanks.

I'm gearing up to etch 2 egodrivers (since there are two on the layout)

Should I etch on one full sized board with the transfer, then cut the board in half and clean afterwards? Or is it best to cut my transfer and boards down, clean them up, and then etch?

Or does it matter one bit?
