Instructions for Use

1. Handling:
   • Use anti-static precautions when handling to prevent electrostatic discharge (ESD) damage.
   • Avoid touching the LED lens with bare hands to prevent contamination and degradation.
2. Soldering:
   • Reflow soldering is recommended for mounting. Preheat the PCB to 150°C for 1-2 minutes.
   • Peak soldering temperature should not exceed 260°C and should be maintained for no more than 10 seconds.
   • Use appropriate solder paste and follow manufacturer guidelines for the reflow soldering profile.
3. Circuit Design:
   • Ensure the forward voltage and current specifications are met to prevent overdriving the LED.
   • Implement current-limiting resistors or constant current drivers to maintain stable operation.
   • Consider thermal management in the PCB design to dissipate heat effectively.
4. Placement:
   • Use automated pick-and-place machines for precise placement on the PCB.
   • Verify the polarity before placement; typically, the longer lead or marked side indicates the anode (+).
5. Testing:
   • Test the LEDs under the recommended operating conditions to verify performance.
   • Check for uniform light output and proper color temperature after soldering.
6. Storage:
   • Store LEDs in a dry environment, ideally with humidity control to prevent moisture absorption.
   • Use moisture barrier bags with desiccants and seal them properly when not in use.

The White LED SMD 1206 Package is a versatile and efficient lighting solution suitable for a wide range of applications.
