10. Precaution for use
(1) Storage
In order to avoid the absorption of moisture, it is recommended to store in a dry box (or
a desiccator) with a desiccant. Otherwise, to store them in the following environment is
recommended.
Temperature : 5ºC ~30ºC Humidity : maximum 65%RH
(2) Attention after open.
LED is correspond to SMD, when LED be soldered dip, interfacial separation may affect
the light transmission efficiency, causing the light intensity to drop. Attention in followed;
a. After opened and mounted the soldering shall be quickly.
b. Keeping of a fraction
Temperature : 5 ~ 40ºC Humidity : less than 30%
(3) In the case of more than 1 week passed after opening or change color of indicator
on desiccant, components shall be dried 10-12hr. at 60±5ºC.
(4) Any mechanical force or any excess vibration shall not be accepted to apply during
cooling process to normal temperature after soldering.
(5) Quick cooling shall be avoided.
(6) Components shall not be mounted on warped direction of PCB.
(7) Anti radioactive ray design is not considered for the products.
(8) This device should not be used in any type of fluid such as water, oil, organic solvent
etc. When washing is required, IPA should be used.
(9) When the LEDs are illuminating, operating current should be decided after
considering the ambient 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 LEDs must be soldered within seven days after opening the moisture-proof
packing.
(12) Repack unused products with anti-moisture packing, fold to close any opening and
then store in a dry place.
(13) The appearance and specifications of the product may be modified for improvement
without notice.
