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:

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 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
