Sources for custom PCB

Sources for custom PCB

(OP)
Hi,
We've been looking for a source that can build custom circuit cards for us. The board layout is actually very simple, it's the details that we have to be picky about. This may go beyond what you're typically used to specifying because it's an aerospace application. We usually plug in the black boxes, not fill their guts. We are now exploring opportunities to do the other part.

We can easily identify suppliers like DigiKey (DK Red) that can make custom boards. The boards they make are OK and we can get configurations to suit our needs. However: The data they supply with the boards doesn't work for us. There's a understanding gap between us and these suppliers as we try to explain what we need. It's probably because they don't supply aircraft quality standards. So who does?

Here are some of the questions that we need to ask of all of our suppliers when buying finished products:
  • Proof of origin
  • Proof of test
  • serialized with date of manufacture
  • (probably more, this is just off the top of my head)
Another way of looking at it: We require a certificate from the supplier that attests that they actually used FR4 substrate, and links that material to a source, their batch, and the test that demonstrated its resistance to fire and any other property defined by the UL spec such as strength and insulation.

This is the standard we uphold for all other materials (seats, airframe, panels, everything).

RE: Sources for custom PCB

Call and talk to Accutrace about your needs.

I used them for years and years until I found I could get boards for a 10th their price elsewhere. You're clearly on a price-is-not-important quest. They're in Silicon Valley so US based.

RE: Sources for custom PCB

We have used Advanced Circuits Inc. (Aurora, CO) for boards that needed to have proof of UL listed materials. Not sure if they could handle the other requirements (serializing, country of origin, etc.). As 'smoked said, not cheap.

Thank you both!
So far a great response from Accutrace.
We'll see if ACI is also interesting.

RE: Sources for custom PCB

You can consider PCBway.
