480nm 485nm LED Blue 3528 SMD LED

480nm LED 3528 SMD LED Package with Phosphor Lens

In order to get the 480nm color from LED, there have two kinds way to make it. 

First, we just need to use the 480nm LED chip and package it in the LED package of what we need, with SMD LED type of LED Lamps type. Putting the LED chip inside the 3528 SMD LED case, bonding the gold wire inside for connection, covering the epoxy lens on the top to protect the LED chip from outside. Then we will get a 480nm LED.

The second way: We will also need to bonding the chip inside for lighting, but in this time, we don't need the 480nm LED, just common blue LED chip. When we comes the epoxy step, we cannot just put the clear epoxy inside. We need to add some phosphor to adjust the emitting color of LED chip, after that, we need to do the separating according the color. After that, we will got different bin code for this LED. After that, the production is done~

This 3528BW48D4L14 were made by the second way, if you need more information about that, just feel free to contact us!

HANDLING PRECAUTIONS:

Compare to epoxy encapsulant that is hard and brittle, silicone is softer and flexible Althouth its characteristiec significantly reduces thermal stress, it is more susceptible to damage by extemal 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, Do not stack together assembled PCBS containing exposed LEDs. Impact may scratch the silicone lens or damage the internal circuitry.

4, 4-A The inner diameter of the SMD pickup nozzle should not exceed the size of the LED to prevent air leaks;

    4-B A plible material is suggested for the nozzle tip to avoid acratching or damaging the LED surface during pickup.

    4-C The dimension of the component must be accurately programmed in the pick-and-place machine to insure precise pickup and avoid damage during production;

    4-D As silicone encapsulation is permeable to gases, some corrosive substances such as H2S might corrode silver plationg of leadframe. Special care should be taken if an LED with silicone encapsulation is to used near such substances. 

5, Please aviod continued exposure to the condensing moisture environment and keep the product away from repid transitions in ambiemt temperature.

6, Product in the original sealed package is recommended to be assembled within 24 hours of opening.
