PACKING & LABEL SPECIFICATIONS
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.
2. Do not directly touch or handle the silicone lens
surface. It may damage the internal circuitry.
1. Handle the component along the
side surfaces by using forceps or
appropriate tools.
4-1. The inner diameter of the SMD pickup nozzle should not exceed the size of the LED to prevent air leaks.
4-2. A pliable material is suggested for the nozzle tip to avoid scratching or damaging the LED surface during pickup.
4-3. The dimensions of the component must be accurately programmed in the pick-and-place machine to insure
precise pickup and avoid damage during production.
5. As silicone encapsulation is permeable to gases, some corrosive substances such as H2S might corrode silver
plating of leadframe. Special care should be taken if an LED with silicone encapsulation is to be used near such
substances.
3. Do not stack together assembled
PCBs containing exposed LEDs.
Impact may scratch the silicone lens
or damage the internal circuitry.
