Well, I had really hoped to find a place like the one you mention in
Toronto... any recommendations, or pricing suggestions? Anyone know of
a place that'll build you a few prototypes if you promise (sign a
contract, whatever) to go with them for the final run (of say, 50-100
boards)? I've googled all over, with very limited success -- and I'd
hate to spend a fortune on this. Anyone know of anything in the New
England (US) area?
BGAs are keeping me from design nirvana -- it would be great to be
able to incorporate faster DSPs/procs/whatever in my design -- no one
seems to make >50 MHz QFPs anymore :(
