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 ne cessary 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.
