The comments here seem to show a typical US-EU divide in perspectives, people talk past each other. Yes, mass-market low-margin consumer products (the US view) probably won't be produced much in the EU in the next few years.
But much of the electronics industry in the EU is B2B and centers around producing high-margin products where 10.000 units of a product would be huge.
The company I work for, for example, usually produces a few hundred units of a product before the next revision replaces it. Whether or not the PCB costs 20€ more or not really isn't that important if you only plan to sell 100 devices of it per year for 10k€ each. Aspects like quality and regulatory conformity are way more important here.
Reminds me that comma.ai has its own line. While their setup is quite expensive they do run production for a smartphone-level of difficulty in-house. They detail it incredibly well at commacon [0].
What I really would love is a JLCPCB equivalent in Europe. Slightly higher prices are OK, but I want to have the the Same amount of process automation and flexibility. Should be good for a scale of a few thousend per year.
I used a Voltera V-One for a few small projects that otherwise would have been breadboarded, and it wasn't bad.

This is painful. They got a used solder mask holder, a Lumen pick and place machine, a bunch of old Siemens feeders, and a small automatic reflow oven. All these tools needed major work. Everything with firmware needed firmware mods. Everything else needed assembly or major cleaning. Everything needed adjustment. They had to 3D print their own solder paste squeegee. They're six months in and still trying to produce one simple board.
I've been down this road of populating a surface mount board. There is a minimum size for a practical board-stuffing operation, and they are below it. They are using prototype techniques for 100 units or so, not techniques that scale.
Surface mount soldering requires applying hot air in a very controlled way, with the temperature ramping up, holding at the high temp for a few seconds, and then ramping down. On a small scale, you have a programmable oven which tries to do that. Those always have heat distribution problems. For production, you have a tunnel oven, with about six sections at different temperatures and a chain conveyor to take the boards through the tunnel. With the tunnel oven, you let the whole thing warm up and stabilize, and when all zones are at the right temperature, you can repeatably solder boards successfully.
They're using a hobbyist-grade pick and place machine. Slow, but cheap. Plus the software isn't ready for prime time. They looked at a used production machine. Runs Windows XP and wouldn't fit through the door. Rejected that.
They're about EUR 30,000 into this, not counting their own labor. This approach is not going to revive electronics in Europe.
