proto boards

Sunstone would be my go-to for that, and you could get the boards in a few days. If you could stand a 3-4 week turn you'll save about a factor of 10 in price by going to OshPark. Oshpark is a board aggregator, but they deal with board houses in the US, not China -- so turns are a bit quicker and quality is more dependable.

I've bought a lot of 2-layer boards from OshPark (and Sunstone), but only a few 4-layer boards from Sunstone.

depending on how they count days and what shipping you choose they might be close to 2 weeks

We use Pentalogix and Gold Phoenix.

I assume you're not talking about Sunstone -- if they say 2 days, they mean shipped in two days, and since they charge you up the wazoo, getting it shipped next day isn't the most significant blow to your pocket book.

(Sunstone has done nice work for me so far -- but they know how much it costs for an engineering team to be sitting there twiddling their thumbs, and they price their service accordingly.)

I use advanced circuits for two layer. ($33 each) they have 4-layer for $66.

You use to be able to get 3 (so ~$100 for 3*$33) but then they raised the minimum to 4 or 5.

I use E-Teknet in Arizona for pretty much all my boards. They are not "dirt cheap" for prototypes, but still pretty competitive, for boards with solder mask and silk screen. Their quality is REALLY good, which is why I like them.

I'll second that, a good company. Only once they messed up by splitting grounds in the Gerbers but did an expedite run for free to make up for this. Everyone can make a mistake and they handled it very professionally.

These days I use complete turn-key:

Once 4pcb left the insulator out between 2 inner layers. They were good about it, replacing the boards quickly. And we've learned to always test before stuffing the boards!

Anyway you can use: pcbshopper.com to find a suitable fab house (based on size, layers, time, quantity...)

I have had good luck with them too. A coworker likes Bittele.

I recently used . Didn't have any problems.

Someone else here recomended them and they turned out to be pretty good. Some problems early on but have been trouble free since. The quality of the boards are very good.

I cast my vote with Advanced Circuits as well. John, who do you usually use for your complex boards?

Looks like Cirexx, Electronic Interconnect, Royal Circuits, Coastal Circuits, Cordova. Purchasing does that, so I don't have much involvement.

We did order the new protos from Myro. I'll let you know how they come out.

Here's the board. It's a mess of different circuits. I'll shear it up into separate bits and parcel out circuits for engineers to build and test.
