Professional Electronics Assembly
Let's face it... Putting together electronics can be hard. This page is intended to be a reference guide for getting something you have designed professionally made. (I'm going to gradually populate this page with more information - DaveB.)
Local Electronics Assembly Shops
DFE Woodlawn/Cincinnati. PB and ROHS. Will do prototype as well as 100+ unit production runs. End-to-end i.e. PCB and PCBA (DaveB has used for his business. Did very well.)
Spectratech Batavia/Greater Cincinnati Tend to work on bigger like multiple thousand production runs. (DaveB has used at a consulting job. Did very well.)
Non-local Electronics Assembly Shops
These are more "traditional" contract assembly shops where you probably are going to need to communicate via email, exchange gerbers, get a quote, etc.
Advanced Circuits - Colorado. PB and ROHS. PCBs and full assembly, based in US, tend to be moderately pricey. (DaveB has used for his business with mixed results.)
Bittele - Canada. untested
Elecrow China, untested
Premiere Manufacturing Colorado, Untested
Screaming Circuits Oregon, untested
Technotronix - California, seem to push fast turn stuff, untested.
Tempo Automation - California,
Non-traditional Electronics Manufacturing Shops
These shops tend to be end-to-end manufacturers that do PCB manufacture, PCB assembly and sometimes component sourcing. They tend to provide an automated web interface for quoting and ordering without the need for emailing and quoting.
Macrofab Houston TX. ROHS only. Will do prototype as well as 100+ production runs. (DaveB has used for his business. Did very well. Very reasonable prototypes if you stay in "standard" spec.)
Circuit Hub untested
PCB-NG Brooklyn, NY. Interesting flat-pricing-per-area model, untested.
