I'm starting a design for a new project using a bunch of 100 pin .5mm pitch pic32mx460's in a TQFP package that we were throwing away at work.
I was hoping that I could use Itead or Seeed to manufacture my boards because the fab we use for prototypes at work would charge 100+ bucks per piece!
Has anyone designed a board with a .5mm pitch? I've been searching online for peoples experiences but so far I haven't found anything conclusive.
I don't care if the yield isn't 100% working. I have 6 or 7 chips and apparently Itead will send you 12 if you opt for the open source option so 75% working yield would be good enough (I know desoldering each chip will be a pain but it still beats paying 100 bucks a board).
I don't really want to waste my time designing only to get 1 or 2 working boards when I need 6 or 7... Also it'd be a waste of 50 bucks.
Edit: I may be wrong about get shipped 12 boards. Rather they make 12 and send 2 out to random people and you get 2 random boards from other people. If anyone could confirm that'd be great
