No doubt there. And it’s something I’ve seen quite a few times over the 30+ years I’ve been involved in/with electronics.
All silicon is not created equal (from life expectancy, to conductivity). All PCB’s are not created equal (from trace depth, to integrity of via’s, to board elasticity). All contact points are not created equal (from plating, to sub-structure materials, to finish)… Which is why I’m so picky (and curious about) quality, and trying to learn who actually makes what. It’s also why I usually don’t care what brand is stamped on it, because it’s the components and workmanship that impress me, as it’s those factors that are relied on the most IMO.
