Wow, I had mistakenly assumed that you couldn't do 0.8 mm BGAs on a hobbyist-level PCB. The solder lands are actually within recommendations. The author mentio

The author mentioned that this is a test board without much hooked up. That really helps, since not every pin needs to be broken out. On a more complex design with higher pin coverage you'd need more layers to be able to route it all.
- Gracana 12y agoThis is actually new, OSH Park has made a couple big improvements in the last year or so; it wasn't possible the last time I looked into it, and even then OSH Park was a bit of an outlier in terms of the small process sizes they could do.
- jesuslop 12y agoI underwrite that wow also, I have fantasies about my own custom FPGA designs, looks that it could be done with garage-like resources following this workflow!

- tcas 12y agoOSH Park is what I would expect form a high level board house, the 4 layer boards are 5/5mil with a good substrate as well
- adestefan 12y agoThey're also looking at adding 6 or 8 layer boards, too.
