why do cheap Chinese electronics work perfectly at first, but quickly get broken afterwards?
In: Engineering
When you buy stuff like that you are seeing the 60% that passed the end of line turn on test, the boards that were broken before it was assembled are not shipped.
Also, many things with chips have firmware on them. If you cheap out development and testing, you can easily have a thing that turns on and runs correctly, then after a week it enters an irrecoverable loop or some cheap memory corrupts and suddenly the thing is a paper weight. or it breaks in a different time zone. Or if you cool then heat the board and it gets humid the contacts corrode or..
Quality product companies spend a lot of time and money finding all those problems and spend money protecting against them. Cheapo companies just ship the thing and hope to get some sales before the 1 star reviews come in.
