Handling Precautions
Compare to epoxy encapsulant that is hard and brittle, silicone is softer and flexible. Although its characteristic
significantly reduces thermal stress, it is more susceptible to damage by external mechanical force.
As a result, special handling precautions need to be observed during assembly using silicone encapsulated
LED products. Failure to comply might lead to damage and premature failure of the LED.
1. Handle the component along the side surfaces by using forceps or appropriate tools.
2. Do not directly touch or handle the silicone lens surface. It may damage the internal circuitry.
3. As silicone encapsulation is permeable to gases, some corrosive substances such as H
2
S might corrode silver plating of
leadframe. Special care should be taken if an LED with silicone encapsulation is to be used near such substances.
