Only one or two I looked at offered an online quote tool, and none of them came even close to the usability and functionality of PCBWay's website. The best one I found was this ridiculously overbuilt system with an embedded 3D engine and one of those shitty 200MB web apps that take 30 seconds to register a click and breaks your back button.
USA is simply not competitive with China on PCBs. For small, cash strapped business, domestic manufacture has never been an option. I expect prices will only go up and up as our entire domestic capacity is absorbed by big corps that can afford the premium. I have no idea how us little guys are supposed to get boards now.
You're not supposed to. It's a backhanded way to quash all competition.
The thing is that China is just really damn good at electronics manufacturing. Their tooling is cutting edge, their workers are career electronics manufacturing workers, and their supply chain is insane.
However I do have a feeling of "if you build it, they will come". But I think it would need to rely heavily on automation. And I'm also not sure how you would deal with the waste in the US. In China the volume is high enough to have local companies that deal with all the byproduct. In the US I would imagine you would have to pay through the nose to dispose of it through some small time contractor 6 states away.
Something like a smartphone would be borderline impossible to do well in the US and keep up with trends.
