* This LED is designed to be reflow soldered on to a PCB. If dip soldered, Nichia cannot guarantee its reliability.

* Reflow soldering must not be performed more than twice. Hand soldering must not be performed more than once.

* 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.

* This product uses silicone resin for the lens and internal pre-coating resin; the silicone resin is soft.

If pressure is applied to the lens, it may cause the lens to be damaged, chipped, and/or delaminated. If the lens is damaged,

chipped and/or delaminated, then the internal connections may be damaged and the reliability may decrease.

Ensure that pressure is not applied to the lens.

If an automatic pick and place machine is used for the LEDs, use a pick up nozzle that does not affect the lens.

Recommended conditions:

Using a nozzle specifically designed for the LEDs is recommended (See the nozzle drawing below).

* Ensure that the nozzle does not come in contact with the lens when it picks up an LED.

If this occurs, it may cause internal disconnection causing the LED not to illuminate.
