Sooo, having recently been involved in building one of these:
I’ll try to explain how modern manufacturing sometimes take shape. This is a prototype. Based on a design by a Belgian Academic (who also built and distributed the first design, made god knows where), it was designed (using kicad) by a German engineer, living in Taipei. I, being a long time user of the initial design, said, hey, I’ll throw some money at this problem. Europe or China? I suggested we could try aisler (where I have always done the first batch of pcbs of a project, in the past). He had never heard of them. But we had both used JLC (in hong kong). Let there be no doubt, JLC rocks at an 8th the price. Still, not gonna stop sending work to aisler to try to keep the home fires burning. Anyway, the components ON the board are made all over. Indonesia, Malaysia, Korea and, of course, China. Now, trying to source components in a BOM based on anything other than a technical specification is nigh to impossible at the moment. So, the providence of the parts is just a question of whether, as in this case, JLC has the tolerances in stock AT ALL (hope, hope, hope).
I have a collection of CMOS which I’m nostalgic about (I also have a lot of printouts of philips and texas instruments specifications). I like designing with it. I like soldering it. Quite a lot of that was still made in Europe or the US. Today, most ALL the electronic components I use are sourced in Asia. That’s many thousands of different parts. In my basement. Our best hope is South Korea. And Taiwan. Include them in the EU. Give them membership in NATO. I kid you not.
I think the Xperia 10ii was made in Thailand, but I’m not sure.
