SOLDERING
• Recommended Reflow Soldering Condition(Lead-free Solder)
● Recommended Soldering Pad Pattern
* This LED is designed to be reflow soldered on to a PCB. If dip soldered or hand soldered,
* 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,
* Repairing should not be done after the LEDs have been soldered.
* The Die Heat Sink should be soldered to customer PCB.
* When soldering, do not apply stress to the LED while the LED is hot.
Nichia cannot guarantee its reliability.
caused by heat and/or atmosphere.
It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing.
If it is difficult or impossible, use high heat-dissipating adhesive.
