F10390 Datasheet, PDF (20/21 Pages) Seoul Semiconductor – Power LED TECHNICAL DATA

21. Precaution for use
(1) Storage
Avoid the absorption of moisture, we recommended to store Z Power LEDs in a dry box
(or desiccator) with a desiccant . Otherwise, store them in the following environment:
Temperature : 5℃~30℃ Humidity : 50% max.
(2) Precaution after opening packaging
However LED is correspond SMD, when LED be soldered dip, interfacial separation
may affect the light transmission efficiency, causing the light intensity to drop.
Attention in followed.
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℃.
(3) Any mechanical force or any excess vibration shall not be applied to apply during
cooling process to normal temp after soldering.
(4) Avoid quick cooling
(5) Components should not be mounted on warped direction of PCB.
(6) Anti radioactive ray design is not considered for the products listed here in.
(7) Gallium arsenide is used in some of the products listed in this publication. These products
are dangerous if they are burned or smashed in the process of disposal. It is also dangerous
to drink the liquid or inhale the gas generated by such products when chemically disposed.
(8) This device should not be used in any type of fluid such as water, oil, organic solvent
and etc. When washing is required, IPA (Isopropyl Alcohol) should be used.
(9) When the LEDs are illuminating, operating current should be decided after considering
the package maximum temperature.
(10) LEDs must be stored to maintain a clean atmosphere. If the LEDs are stored for 3 months
or more after being shipped from SSC, a sealed container with a nitrogen atmosphere
should be used for storage.
(11) The appearance and specifications of the product may be modified for improvement
without notice.
(12) The package with lens can NOT be solder reflowed. It will damage the lens.
(13) Long time exposure of sunlight or occasional UV exposure will cause lens discoloration.
(14) Slug polarity is anode.
