Thanks to all for the useful suggestions. Unfortunately I'm stuck
with BGAs for the FPGAs I want.
Mark: I don't need to route all pins, only about 100 so I only need
to route the outermost rows.
Norm and timbomcnuckle: thanks for the links, I will take a look at
them.
Leon: I thought about having them done professionally but all the
quotes I got were like $500 for one board. The thing is I'll
probably need 2-3 iterations to make my design work ... quite a lot
of money for a hobby. The equipment is not expensive though (the hot
air stations are Chinese).
If you know a place where I can get a resonable price, please let
me know. It might be just that they solder the BGAs (1-2 per board)
and I would manually solder the rest.
Right now I'm leaning towards getting a Chinese hot air station AND
getting a toaster oven to "upgrade" to a reflow oven.
Any more suggestions, please keep them coming. Probably other
members wanted at some point to use BGAs but stopped because they
thought it would be too difficult.
