  • 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. IR Reflow Soldering Profile (Lead-free Solder) 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. © All Rights Reserved The above specifications are for reference purpose only and subjected to change without prior notice
