And they’re not the sort of places where you get boards for consumer electronics made. They’re doing microwave/high frequency boards for companies like Boeing.
They'll absolutely do consumer product assembly. It's short-run versus mass-production that's the real problem, most of them just aren't set up for high volume.
Board fab though, not so much. I don't think we have a PCB fab left in the area after losing Prototron. I'd be more sad about that, except that I don't think I ever had a single order with Prototron that actually went smoothly and came back correctly.
