Hi guys,
recently I have many problems with SMD LEDs. The most common problem is some kind of leakage in silicone encapsulation. It might be air but I have no idea what is the root cause of it. Do you have any ideas? Is it dangerous? What can be done to prevent it? Is it encapsulation process fault?
LED after putting into tester first shines few times, than start to work normally. After about month they become damaged permanently.
Here are some photos of good and bad one.
