* The product is designed to be reflow soldered to a PCB. If you use dip soldering for the products,

Nichia cannot guarantee its reliability.

* Reflow soldering must not be performed more than twice. Manual soldering must only be done once.

* Care should be taken to avoid cooling at a rapid rate and ensure the peak temperature ramps down slowly.

* Customer is advised to use nitrogen reflow soldering as air flow process can cause optical degradation due to the heat and

atmosphere of reflow soldering.

* Since silicone used as encapsulating resin in this product is a soft material, do not press on the encapsulant.

Failure to comply might lead to nicks, chip-outs, delamination and deformation of the encapsulant, bump breakage

and an adverse effect on product 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, avoid applying any stress to the LED package while heated.
