... and to think that I was (silently) complaining about the 5-working-day turnaround of the local guys. Of course, they charged more than $70 because we're talking about US-based labor. At least they would work without a stencil for small runs where the cost of a one-time stencil didn't make sense. I believe they just hand-painted the paste before turning on the pick-and-place.

> Super true Brian, the difference here is turnaround time and price. I can submit a new design to JLC, let's say for an analog eurorack module, and get 20 pieces back with all SMD soldered (even some through hole, if common enough) in 2 weeks or less, for ~$70 total. All of this without talking to anyone.
> PCBCart, who I've worked with for years, takes about 8 weeks with ~$2k minimum if I want a reasonable unit cost. They're awesome, and when I need hundreds of something I often go with them.

>> There's no need to limit yourself to JLC. There are tons of PCB Assembly houses around the world. Depending upon where you live, one might even be nearby. I used to live in Bellevue, WA, and there is a PCB Assembly shop just a 10-minute walk from my home there. They got to know me on a first-name basis, and would have rework done over lunch.
>> When it came to full assembly, I would simply provide the PCB from the fab and the parts from Mouser, DigiKey, Jameco, etc. Of course, I made mistakes from time to time, but they would always let me know when my counts were off. I learned that they prefer to have at least 10 spare parts on the tapes because they need some room to feed the pick-and-place. The local guys basically trained me on how to provide them what was needed. As you folks are saying, even a slight amount of time learning how to enable automation pays off many times in efficiency. Also, the boards look absolutely perfect (compared to any of my hand-soldering).

>>> heh yeah Mike, I'd say "an order of magnitude" more productive. I'm really looking forward to consignment parts too. it would be quite the game changer if they could stuff 2164s, SSI or AS parts, solder through hole on the opposite side of the smd, etc. funny how much better they do this than any other service, even with their huge limitations. Super Synthesis wouldn't really work without them right now, I'm very grateful.
