PRECAUTIONS FOR HANDLING ELECTROSTATIC SENSITIVE LEDs
Static Electricity and Surge
Static electricity and surge will damage the LED and a high standard of care must be taken during handling. It is recommended that a wristband, conductive mat or
anti-electrostatic glove is used when handling the LEDs. All devices, equipment (e.g. soldering iron points) and machinery must be properly grounded.
SAFETY PRECAUTIONS FOR HANDLING HIGH BRIGHTNESS LEDs
The light output of the Products may cause injuries to human eyes in circumstances where they are viewed directly with unshielded eyes for more than a few seconds.
Please refer to European Standard BSEN 100015-1 1992

WHITE DISCRETE LEDs - Technical Info.
USAGE INFORMATION ON WHITE LEDS
White LEDs are produced by combining blue LEDs and special
phosphors and consequently the colour can vary slightly if different
operating currents are used.
Lead Forming
During forming the leads should be bent at a point at least 3mm from
the base of the epoxy. The base of the leadframe should not be used
as a fulcrum during lead forming.
Lead forming should be carried out before soldering.
Do not apply any bending stress to the base of the lead as the stress
may damage the LED.
When mounting the LED onto a PCB, the holes drilled on the PCB should be exactly aligned with the leads on the LED
because if the LEDs are mounted with stress at the leads degradation of the epoxy resin could result.
Soldering Conditions
Do not solder the LEDs at a distance closer than 3mm from the base of the epoxy. Soldering the LED below the stand
off is recommended.

DISCRETES

Do not apply any stress to the lead particularly when heated.
The LEDs must not be repositioned after soldering
After soldering the LED, the epoxy bulb should be protected from mechanical shock or vibration until the LED returns
to room temperature.
Direct soldering onto a PC board should be avoided. Mechanical stress to the epoxy may be caused from warping of
the PC board or from the cutting of the leadframes. When it is absolutely necessary, the LEDs may be mounted
directly onto the board but the user must assume responsibility for any problems.
Direct soldering should only be done after testing has confirmed that no damage will occur.
LEDs should not be soldered directly onto double sided PCB's because the heat will deteriorate the epoxy resin.
When it is necessary to clamp the LED to prevent soldering failure it is important to minimise the mechanical stress on
the LED.
Cut the LED leadframe at room temperature as cutting at high temperature can lead to failure of the LED.

WHITE DISCRETE LEDs - Technical Info.
USAGE INFORMATION ON WHITE LEDS Ctd.
Static Electricity and Surges
Both of the above will damage the LED. It is recommended to use a
wrist band or antistatic glove when handling the LEDs. In addition all
devices, equipment and machinery must be properly grounded.
Typical static electricity resistance figures are
Withstand voltage:
Standard test method:
Condition A
Heat Generation
This must be taken into account when using the LEDs as the temperature gets higher when the LEDs are densely
mounted. It is necessary to design the circuit so that the operating temperatures are within the absolute maximum
ratings of the device.
The operating current should be decided after consideration of the maximum ambient temperature when the LEDs are
illuminated.
Cleaning
Avoid exposure to chemicals as they may discolour and damage the epoxy. When washing is required isopropyl
alcohol should be used.
The influence of ultrasonic cleaning depends on how the LEDs are mounted and factors such as speed of oscillation.
Before cleaning using this method tests should be carried out to ensure the LED will not be damaged.
Other points
Care must be taken so that reverse voltage will not exceed the absolute maximum rating when using LEDs with a
matrix driver.
As the leads are silver plated they may become discoloured with Hydrogen Sulphide and other gaseous chemicals.
Precautions must be taken to maintain a clean storing atmosphere.
The LED light output is strong enough to damage the human eye and precautions must be taken to prevent looking
directly at the LED with unaided eyes for more than a few seconds.
