Do not apply current to the LED until it has cooled down to room temperature after soldering Recommended soldering conditions: IR Reflow Soldering Profile IR Reflow Soldering Profile for Lead Free Soldering Manuel Soldering Recommended Soldering Patterns soldering time soldering temperature power of iron max. 3 s max. 260 °C max. 25 W recommended max. thermal resistance device-ambient: 20 K/W 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. www.roithner-laser.com 4 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: During operation these LEDs do emit high intensity UV light, which is hazardous to skin and eyes, and may cause cancer. Do avoid exposure to the emitted light. Protective glasses are recommended. It is further advised to attach a warning label on products/systems that do utilize UV-LEDs. 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 www.roithner-laser.com 5
