Another test board & focus ramp

A project log for Powder coat pcb with toner & laser sinter

So we powder coat a blank PCB with laser toner. Selectively melt with laser engraver and maybe get some good results.

This is the ramp to check my focus, to the right is on the table, to the left is raised 3/4". Bottom line is 40% laser, 6th from the bottom is 15%. I still see smoke @ 15%, but I'm going to try it on the rest of the board.

So I shot this at table height @ 15% laser.

This is most certainly usable, I'd etch it but it's a mistake design I don't need. There's no voids or any of those missing spots you get with the paper peeling method. Just a nice layer everywhere it was intended to be. No guessing with the iron. Plus I'm washing my hands quite a bit with the leaky pickle jar powder gun. As soon as the real one gets here (movement now) this thing is going back to killing flies.
