Precautions
Soldering:
• Do avoid overheating of the LED
• Do avoid electrostatic discharge (ESD)
• Do avoid mechanical stress, shock, and vibration
• Do only use non-corrosive flux
• Do not apply current to the LED until it has cooled down to room temperature after soldering
Recommended soldering conditions:
This LED is designed to be reflow soldered on to a PCB. If dip soldered or hand soldered, its
reliability cannot be guarantee.
Nitrogen reflow soldering is recommended. Air flow soldering conditions can cause optical
degradation, caused by heat and/or atmosphere.

Recommended Soldering Patterns
Unit: mm
Above table specifies the maximum allowed duration and temperature during soldering. It is
strongly advised to perform soldering at the shortest time and lowest temperature possible.
Cleaning:
Cleaning with isopropyl alcohol, propanol, or ethyl alcohol is recommended
DO NOT USE acetone, chloroseen, trichloroethylene, or MKS
DO NOT USE ultrasonic cleaners
Static Electricity:
LEDs are sensitive to electrostatic discharge (ESD). Precautions against ESD must be taken
when handling or operating these LEDs. Surge voltage or electrostatic discharge can result in
complete failure of the device.
Radiation:
Those LEDs do emit invisible light, which is invisible and may cause cancer. Do avoid exposure
to the emitted light. It is further advised to attach a warning label on products/systems.
Operation:
Do only operate LEDs with a current source.
Running these LEDs from a voltage source will result in complete failure of the device.
Current of a LED is an exponential function of the voltage across it. Usage of current regulated
drive circuits is mandatory.
