Notes:
*This LED is designed to be reflow soldered on to 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 conditions can cause optical degradation,
caused by heat and/or atmosphere.
*Since the glass used in the encapsulating glass is fragile, do not press on the hermetic glass.
pressure can cause nicks, chip-outs, Sealant la[x]yer and deformation, and wire breaks, decreasing reliability
*Repairing should not be done after the LEDs have 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 impossible, use high heat-dissipating 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 not designed in a manner
Where the flux will come in contact with the LEDs.
*Make sure that there are no issues with the type and amount of 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。从高温度逐渐降低温度。
*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。磁通量将与发光二极管接触的地方。
*确保使用的焊料类型和数量没有问题。

CAUTIONS
1. Handling Precautions
● 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 glass can 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 into the UV light, even through an
optical instrument.
●  UV protective glasses are required to use in order to avoid damage by UV light in case of
viewing UV light directly.
