* 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.

* Since the silicone used in the encapsulating resin is soft, do not press on the encapsulant resin.

Pressure can cause nicks, chip-outs, encapsulant delamination and deformation, and wire breaks, decreasing reliability.

* Repairing should not be done after the LEDs have been soldered. When repairing is unavoidable,

a double-head soldering iron should be used.

It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing.

* When soldering, do not apply stress to the LED while the LED is hot.
