www.roithner - laser.com 4 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 only solder the leads. soldering of header or cap will damage the led ? do only cut the leads at room temperatur e with an esd protected tool ? do not solder closer than 3 mm from base of the header ? do form leads prior to soldering ? do not impose mechanical stress on the header when forming the leads ? do not apply current to the led until it has cooled down to room tempe rature after soldering recommended soldering conditions: dip soldering hand soldering pre - heat time max 30 s soldering time max 5 s dipping time max 5 s solder bath temperature max 190 c solder temperature max 190 c 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 el ectricity: uvtop 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. uv - radiation: during operation these leds do emit high intensity ultraviolet light , which is hazardous to skin and eyes , and may cause cancer. do avoid exposure to the emitted uv 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 uvtop 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 class 1
