Delarre

Just finished making the PCB for a little LED project I’m working on with a friend for BurningMan this year. Didn’t turn out as well as hoped, had some problems with undercutting, and lost a few tracks.

Definitely need to improve the technique. We used the Toner Transfer method to move the toner from a piece of glossy photo paper to the board, then etched with Ferrich Chloride solution.

Initially didn’t heat the etchant but tried to use a sponge to agitate it, I think this probably didn’t help with the undercutting. Plus I accidentally rubbed off some of the toner.

Still, it’ll work for our initial prototype, and give us enough feedback to modify the board before getting it professionally printed.
