SOLDERING
• Recommended Reflow Soldering Condition(Lead-free Solder)
● Recommended Soldering Pad Pattern
* The product is designed to be reflow soldered to a PCB. If you use dip soldering for the products,
* 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
* Since silicone used as encapsulating resin in this product is a soft material, do not press on the encapsulant.
* Repairing should not be done after the LEDs have been soldered. When repairing is unavoidable,
* When soldering, avoid applying any stress to the LED package while heated.
Nichia cannot guarantee its reliability.
due to the heat and atmosphere of reflow soldering.
Failure to comply might lead to nicks, chip-outs, delamination and deformation of the encapsulant, bump breakage
and an adverse effect on product reliability.
When using automatic pick and place machine, use a pick up nozzle which does not directly apply stress
to the encapsulation of the LEDs.
Recommended conditions:
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.
1 to 5°C per sec
It is recommended to use a pick up nozzle designed for the LEDs. (See Figure below.)
* Avoid direct contact to the resin lens

Failure to comply might result in catastrophic failure
of the LEDs due to bump damage or breakage.
