I don’t know any of those shops, but we still have some regional ones like Hughes Circuits, Streamline, and TTM (was VIA systems). There are actually dozens of shops, of highly variable capability
haha! I've been to Hughes! I used to service the UV exposure machines. They had Olec machines. I also used to go into Sanmina (sp?) and other shops down there (VIA systems too). It's been so long I can't remember all the names. I think most shops that didn't move off-shore are now mostly R&D and quick turn. The huge high volume shops are mostly gone. There were dozens and dozens in SoCal and the Bay Area way back when.
