Only someone who is either totally naive or willfully dishonest intellectually can make the claim you just made. Obviously you’ve either never worked in the electronics field, or if you have you’ve never worked in a proper QA role and/or taken quality seriously. Of course I work with a lot of people on the supplier side in a major medical device manufacturer that think the same exact way you just did - it is terrifying to think we rely on people who think like this...
What kind of idiot QA person thinks that they should blindly trust a component just because it's supplied by a "domestic" company.
So you exclude all chinese chips? What about Singapore? Texas Instruments chips made in Singapore? Germany? Japan?
What's worse? A potential adversary looking to sell knock-off chips to us, or a domestic "QA expert" who can't tell the difference between a boogieman and a burn-in chamber?
