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.
Real one on the right. Be careful!
