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 temperature 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 temperature after soldering

Recommended soldering conditions:

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:

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
