Ok, a s.e.design thread has got me thinking about pan-frying BGAs.
Now I'm curious. What's a good BGA to start with? "Good" is defined
as:
1. Inexpensive, cause I'll probably toast a few.
2. Useful, because it's good to see results.
3. Easy to design around, because I want to worry about the soldering
process, and not burn through a number of chips getting the design
4. Require a minimum of support components.
5. Not so complex that lots of tiny vias would be needed. If I can
get by with two rows pulled out on the top with 7/7 rules, and the
remaining rows tied to gnd/vcc through one or two big vias, that's
acceptable.
