Cautions:

1.Storage  
Before opening the package:The LEDs should be kept at 5~30°C and 60%RH or less. The LEDs should be used within a year. After opening the package:The LED must be used within 24 hours, else should be kept at 5~30? and 30% RH or less. The LEDs should be used within 7days after opening the package. If unused LEDs remain, they should be stored in moisture proof pachages .recommend to return the LEDs to the original moisture proof bag and to reseal the moisture proof bag again. If the LEDs have exceeded the storage time, baking treatment 
should be performed more than 24 hours at 60 ± 5°C.


2.Soldering Iron
  When hand soldering, keep the temperature of iron below less 300? less than 3 seconds
  The hand solder should be done only one times


3.Repairing 
Repair should not be done after the LEDs have been soldered. When repairing is unavoidable, a double-head soldering iron should be used (as below figure). It should be confirmed in advance  whether the characteristics of LEDs will or will not be damaged by repairing.




Handling Precautions:

1.Compare to epoxy encapsulant that is hard and brittle, silicone is softer and flexible. Although its characteristic significantly reduces thermal stress, it is more prone to damage by external mechanical force . As a result, Special handling precautions must be observed during assembling using silicone encapsulated LED products, Failure to comply might leads to damage and premature failure of the LED.




2.Handle the component along the side surface by using forceps or appropriate tools; do not directly touch or Handle the silicone lens surface, it may damage the internal circuitry.




3.The outer diameter of the SMD pickup nozzle should not exceed the size of the LED to
 prevent air leaks. The inner diameter of the nozzle should be  as large as possible. A pliable
 material is suggested for the nozzle tip to avoid scratching or damaging the LED surface during 
pickup. The dimensions of the component must be accurately programmed in the pick-and-place machine to insure precise pickup and avoid damage during production.




4.Do not stack together assembled PCBs containing LEDs.Impact may scratch the silicone lens or damage the internal circuitry.




5.Not suitable to operate in acidic erivironmengt.PH<7.
