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
pre-heat time
dipping time
solder bath temperature
max 30 s
max 5 s
max 190 °C
soldering time
solder temperature
hand soldering
max 5 s
max 190 °C
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:
Class 1
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
