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, 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,
* Since the silicone used in the encapsulating resin is soft, do not press on the encapsulant resin.
* Repairing should not be done after the LEDs have been soldered. When repairing is unavoidable,
* When soldering, do not apply stress to the LED while the LED is hot.
caused by heat and/or atmosphere.
Pressure can cause nicks, chip-outs, encapsulant delamination and deformation, and bump breaks, decreasing 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

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