Soldering Conditions
•
•
•
DO NOT apply any stress to the lead particularly when heat.
After soldering the LEDs should be protected from mechanical shock or vibration until the LEDs
return to room temperature.
When it is necessary to clamp the LEDs to prevent soldering failure, it is important to minimize the
mechanical stress on the LEDs.

Static Electricity
•
•
LEDs are very sensitive to Static Electricity and surge voltage. It is recommended to always wear
a wrist band or an anti-electrostatic glove when handling the LEDs.
All devices, equipment and machinery must be grounded properly. It is recommended that
precautions should be taken against surge voltage to the equipment that mounts the LEDs.
