Fake voltage regulators

Posted: October 12, 2015 at 8:51 am, Category: Devices,

I’ve heard before about the fake ICs but never seen it in real life. Here is a first of them was captured accidentally in our new butch. The real magic that not all of them are bad. I was found one during the routine test, which is really noisy. But after that the more detailed analysis showed that there is just about 10% of them are problematic. Though, I didn’t check the voltage drop yet and thinking it would be better to resolder all of them for originals, to make sure that everything will be fine during regular operation.
