The dipmicro tqfp32 adapter is discontinued from their site but I've gotten that exact same one from Futurlec.com for a decent price.

They're pretty good but they sometimes forget about your order if something is on backorder and you have to harass them. Otherwise very cheap with good (tiered) shipping prices and reasonable delivery times from Asia to NA.

How about Olimex (http://www.olimex.com/pcb/)?



I don't know. Have you used them?

The feedback on "I used X and it worked" is great; thanks everyone!

I have been trying to get a dense board that was autorouted in eagle thru the Olimex design rule check (DRC) (and this board has way more stuff than a 2 layer board as a right to have!). Can't get there with Olimex, too many clearance issues.
Same design passes iteadstudio just fine - my conclusion is that the Olimex build process cannot handle the levels of professional build work that iteadstudio can.

An additional issue is the minimum order size.
Places that order by area generally have a minimum that costs too much.

Here's what I can find:
international circuits: $125
pcbexpress: $109
pcb-pool: $65/$120 (w/o or with mask)
ap circuits: $57 / $85 (w/o or with mask)
expresspcb: $51/$61 (w/o or with mask)
olimex: $30

If I can pass the olimex DRC, that might be pretty competetive. Anyone used them?

Also, I have one part with square leads (a connector). Seems these places don't like overlapping drill hits. I wonder what I can do about this... Other than specify a big hole :-/
