Notes:
*This LED is designed to be reflow soldered o*a PCB. If dip soldered or hand soldered,
We cannot guarantee its reliability.
*Reflow soldering must not be performed more than twice.
*Avoid rapid cooling. Ramp down the temperature gradually from the peak temperature.
*Nitrogen reflow soldering is recommended. Air flow soldering condition*an cause optical degradation,
caused by heat and/or atmosphere.
*Since the glass used in the encapsulatin*lass is fragile, do not press on the hermetic glass.
pressure can cause nicks, chip-outs, Sealant layer and deformation, and wire breaks, decreasing reliability
*Repairing should not be done after the LEDs h*e been soldered.
It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing.
*The Die Heat Sink should be soldered to customer PCB. If it is difficult or im*sible, use high hea*ssipating adhesive.
*When soldering, do not apply stress to the LED while the LED is hot.
*When using a pick and place machine, choose an appropriate nozzle for this product.
*When flux is used, it should be a halogen free flux. Ensure that the manufacturing process is no*signed in a manner
Where the flux will come in contact with the LEDs.
*Make sure that there are no issues with the type and amou*f solder that is being used.

*此LED设计为回流焊接到印刷电路板上。如果是浸焊或手工焊，我们无法保证其可靠性。
*回流焊接不得超过两次。
*避免快速冷却。从.温度逐渐降低温度。
*建议采用氮气回流焊接。气流焊接条件会导致光学性能下降，由热和/或大气引起。
*由于封装玻璃中使用的玻璃易碎，请勿按压密封玻璃。压力会导致缺口、切屑、密封剂层和变形，以及断丝，降低可靠性。
*在焊接LED后，不应进行维修。应事先确认修理是否会损坏LED的特性。
*模具散热器应焊接到客户印刷电路板上。如果困难或不可能，使用高散热粘合剂。
*焊接时，不要在LED发热时对其施加应力。
*当使用拣配工具时，请为本产品选择合适的夹具。
*使用助焊剂时，应为无卤助焊剂。确保制造工艺的设计不符合要求。磁通量将与发光二****管接触的地方。
*确保使用的焊料类型和数量没有问题。

CAUTI*
1. Handling Precauti*
● Do not handle the LEDs with bare hands as it will contaminate the LEDs surface and may
affect the optical characteristics.
● When handling the product with tweezers, be careful not to apply excessive force to the
glass. Otherwise, the glas*an be cut, chipped, delaminate or deformed, causing wire-bond
breaks and catastrophic failures.
■  Dropping the product may cause damage.
2. Electrostatic Discharge (ESD)
● The product are sensitive to static electricity or surge voltage. ESD can damage a die and
its reliability. When handling the products, the following measure against electrostatic dis-
charge are strongly recommended:
Eliminating wrist strap, ESD footwear, clothes, and floors
Grounded workstation equipment and tools
ESD table/shelf mat made of conductive materials
● Ensure that tools, jigs and machines that are being used are properly grounded and that
proper grounding techniques are used in work areas. For devices/equipment that mount the
LEDs, protection against surge voltages should also be used.
● The customer is advised to check if the LEDs are damage by ESD
When performing the characteristics inspection of the LEDs in the application.
Damage can be detected with a forward voltage measurement at low current(≤1mA).
3. Eye Safety
● Please proceed with caution when handling any UVLEDs driven at low or high current.
Since UV light can be harmful to eyes, do Not look directly i* the UV light, even through an
optical instrument.
●  UV protective glasses are required to use in order to *oid damage by UV light in case of
viewing UV ligh*rectly.

注意事项
1. 处理措施
●不要徒手操作LED灯,因为它将发光二****管表面污染和可能影响光学特性。
●用镊子夹LED灯时,注意不要过度使用*夹住玻璃。否则，玻璃可能会被切割、*碎、分层或变形，导致金属丝粘结断裂和灾难性故障。
■产品掉落可能造成损害。
2. 静电放电(ESD)
●产品对静电或电压冲击敏感。静电可以损坏模具和它的可靠性。处理产品时，应采取以下防静电措施
强烈建议:
消除腕带，静电鞋，衣服和地板上面的静电
做好接地防静电
由导电材料制成的静电桌子/搁板垫子
●确保工具、夹具和机械使用正确接地
确保正在使用的工具、夹具和机器正确接地，并在工作区域使用正确的接地技术。对于安装led的设备，也应该使用****浪涌电压的保护。
●建议客户检查LED 灯是否被ESD损坏
在应用程序中对led进行特性检查时。
检测伤害要在低电流正向电压测量(≤1 ma)。
3.眼睛安全
●请谨慎处理任何UVLEDs驱动的低或高电流。
因为紫外线*睛*，所以不要直视紫外线，即使是通过光学仪器。
●在直接观看紫外线的情况下， 为了避免紫外线的伤害，需要使用防紫外线眼镜
