Recommended Land Layout (Unit: mm)
1. 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.
Soldering Conditions
2. Static Electricity
• The LEDs are very sensitive to Static Electricity and surge voltage. So it is recommended
that a wrist band or an anti-electrostatic glove be used 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.
