Surface-mount LED Board!

Since fabricating my Roomba controller board, I’ve been working to improve my PCB capabilities. My distant goal is design a complete embedded system with chips that are only available in surface-mount packages. Here’s a small LED PCB I began designing over the weekend:

LEDs on, mirrored

Actually, that’s a mirror image of the board because I forgot to flip the layout before I etched the PCB. Whoops Here’s the schematic and layout, in gschem and pcb:

Here’s some more pictures:

I’ve started using flux (probably essential for surface-mount) and I ran into trouble with some of the finer traces breaking during etching. I damaged the center LED, so it’s a bit dimmer… maybe I’ll replace it later.
