LED SMD PLCC 2 3528 Blue SMT LED

3528 SMD LED PLCC-2 460nm 465nm Blue SMD LED;

SMD LED have kinds of size of package, such as 3528 SMD LED, 5730 SMD LED, 2835 SMD LED, 5050 SMD LED ect. The one that we discussed today is 3528 SMT LED, which have the size of 3.5*2.8*1.9mm(thickness). There will have two pad in the bottom of SMD LED to conntect the circuit, in this case, we also name is as PLCC 2 3528 SMD LED. We produce this Blue SMD LED with 465nm LED inside for lighting source with common bright type.

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.
