10. Precaution for Use
1) Storage
• Before opening the package
Avoid the absorption of moisture, we recommended to store High Flux LEDs in a dry
box(or desiccator) with a desiccant . Otherwise, store them in the following environment:
Temperature : 5℃~30℃ Humidity : 50% max.
• After opening the package
a. Soldering should be done right after opening the package(within 24Hrs).
b. Keeping of a fraction
- Sealing
- Temperature : 5 ~ 40℃, Humidity : less than 30%
c. If the package has been opened more than 1week or the color of desiccant changes,
Components should be dried for 10-12hr at 60±5℃
• Any mechanical force or any excess vibration shall not be accepted to apply during cooling
process to normal temp. after soldering.
• Avoid quick cooling
• Leadframes are silver plated copper alloy. The silver plate surface may be affected by
environments which contains corrosive substances. Please avoid conditions which may cause
the LEDs to corrode, tarnish or discolor.
2) Static Electricity
• Static Electricity and surge voltage damage the LEDs. 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 properly grounded.
It is recommended precautions be taken against surge voltage to the equipment that mounts
the LEDs.
3) Heat Generation
• Thermal is one of the important parameter to design the end product. Please consider the heat
generation of the LEDs.
• The operating current should be decided after considering the ambient maximum temperature
of LEDs.
