Package is a key factor, and affects the reliability of LED. In this paper, the main failure modes and mechanisms that caused by poor package process were investigated through some failure analysis cases, and some improving methods to improve the LED's reliability are put forward.
Aiming to study dynamic mechanical properties of the transparent silicone resins for LEDs packaging and the effects of dynamic mechanical properties on the reliability of high power LEDs, dynamic mechanical analysis (DMA) has been adopted to study one silicone resin used for packaging high power white light LEDs. The viscoelastic behavior of silicone resin was obtained from multi-frequencies dynamic...
