After reflow soldering rapid cooling should be avoided
Use the following conditions shown in the figure.
<Pb-free solder> <Lead solder>
1.Reflow soldering should not be done more than two times
2.When soldering,do not put stress on the LEDs during heating
Handling Precautions
Compare to epoxy encapsulation 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 product, Failure to comply might leads to damage and premature failure of the LED.
? 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.
? Do not stack together assembled PCBs containing LEDs. Impact may scratch the silicone lens or damage the internal circuitry.
? Not suitable to operate in acidic environment, PH<7.
? LED operating environment and sulfur element composition cannot be over 25 PPM in the LED mating usage material.
When we need to use external glue for LEDs application products, please make sure that the external gluematches the LEDs packaging glue. Additionally ,as most of LEDs packaging glue is silica gel, and it has strong Oxygen permeability as well as strong moisture permeability; in order to prevent external material from getting into the inside of LEDs, which may cause the malfunction of LEDs, the single content of Bromine
element is required to be less than 225 PPM,the single content of Chlorine element is required to be less than225PPM,the total content of Bromine element and Chlorine element in the external glue of the applicationproducts is required to be less than 375 PPM.
? The encapsulated material of the LEDs is silicone. Therefore the LEDs have a soft surface on the top ofpackage. The pressure to the top surface will be influence to the reliability of the LEDs. Precautions should betaken to avoid the strong pressure on the encapsulated part. So when using the picking up nozzle, the pressureon the silicone resin should be proper.
? Static electricity or surge voltage damages the LEDs. Damaged LEDs will show some unusual characteristicssuch as the lower forward voltage, or the not light at low current, even not light. All devices, equipment andmachinery must be properly grounded. At the same time, it is recommended that wrist bands oranti-electrostatic gloves, anti-electrostatic containers be used when dealing with the LEDs.
Storage
? Before opening the package, the LEDs should be kept at 30? or less and 60%RH or less. The LEDs shouldbe used within a year.
? After opening the package, the product should be stored at 30? or less and humidity less than 10% RH, andbe soldered within 24 H. It is recommended that the product be operated at the workshop condition of 30?or less and humidity less than 60% RH. If unused LEDs remain, they should be stored in moisture proofpackages, such as sealed containers with packages of moisture absorbent material (silica gel). It is alsorecommended to return the LEDs to the original moisture proof bag and to reseal the moisture proof bagagain.
