LED Packaging with Silicone Encapsulants

When working together, the packager and silicone provider should take into account several details. One major consideration is the methodology used when packaging an LED, such as surface mount LED, compression molding or injection molding. Besides that, the end use of the LED and the longevity of the LED must be addressed. As we often find, producing an LED is a game of compromise – durability versus reliability. We will explore some of the basics of silicone to get a better understanding of the material. Also, we will delve into a few questions to be asked when packaging an LED, such as what type of material to use or what RI should be targeted. In all cases, the necessity of a relationship between the silicone provider and the LED manufacturer will become clearer.
