This is not an FPGA project, but it has some useful info about oven-soldering BGA parts with 0.8mm ball pitch:

Also about 4-layer PCBs.

This is pretty impressive work indeed. A shame the author didn't mention costs of having the PCB made.

FWIW, I'm going to be following that guy's blog. It looks like he's into some pretty interesting stuff.

2 layer boards are $5 per square inch (with 3 copies of your board included in that price) and ship in under 12 calendar days from ordering.
4 layer boards are $10 per square inch (also including 3 copies of your board), go to the fab once a week, and have a 2 week turn time from the fab.

It definitely is! I only use it for prototypes and up to half-eurocard, the prices are good. The smaller, the better. ;)
