Update Aug 26, 2016: See post #61 on page 7 for Eagle files, BOM, and Gerbers, as well as pics of the final board.
Original post:
I am working on a tpa3118d2 PCB. This is literally the first PCB I've ever designed. It's not yet fully complete, but I'd like to think I'm done with the major design, and getting to the fine-tuning phase. So I was hoping to solicit some comments, critiques, tips, etc.
My main goal here was to familiarize myself with the PCB design and manufacturing process.
The schematic is an almost verbatim copy of DUG's DUG-1 PBTL board. DUG was nice enough to let me copy his design. It's not as fancy as the GMARSH Wiener boards, and that's not what I'm going for. I really like the DUG-1 boards, and basically want those with a few small tweaks:
I haven't created the ground plane yet, only the signal and power lines are routed.
I know there is an error on the output side, it seems Eagle is omitting a net.
Thanks for any feedback!

- Use of Coilcraft VER2923 inductors to save some board space
- Room for through-hole input capacitors (actually I'll probably tweak the design a bit so you can use either SMD or leaded)
- Room for multiple OS-CON caps
- Room for leaded caps in part of the output filter
