● Product complies with JEDEC MSL 3 or equivalent. See IPC/JEDEC STD-020 for moisture-sensitivity details.
● Absorbed moisture in LED packages can vaporize and expand during soldering, which can cause interface delamination
and result in optical performance degradation. Products are packed in moisture-proof aluminum bags
to minimize moisture absorption during transportation and storage.
Included silica gel desiccants change from blue to red if moisture had penetrated bags.
● After opening the moisture-proof aluminum bag, the products should go through the soldering process
within the range of the conditions stated above. Unused remaining LEDs should be stored with silica gel desiccants
in a hermetically sealed container, preferably the original moisture-proof bags for storage.
● After the “Period After Opening” storage time has been exceeded or silica gel desiccants are no longer blue,
the products should be baked. Baking should only be done once.
● The leads or electrode pads (anode and cathode) of the product are plated with silver. Exposure to a corrosive environment
might cause the silver plated the leads or electrode pads to tarnish, and thus leading to difficulties in soldering.
If unused LEDs remain, they must be stored in a hermetically sealed container.
Nichia recommends using the original moisture-proof bag for storage.
● Do not use sulfur-containing materials in commercial products. Some materials, such as seals and adhesives, may contain sulfur.
The extremely corroded or contaminated plating of LEDs might cause an open circuit. Silicone rubber is recommended
as a material for seals. Bear in mind, the use of silicones may lead to silicone contamination of electrical contacts
inside the products, caused by low molecular weight volatile siloxane.
● To prevent water condensation, please avoid large temperature and humidity fluctuations for the storage conditions.
● Do not store the LEDs in a dusty environment.
● Do not expose the LEDs to direct sunlight and/or an environment where the temperature is higher than
normal room temperature.
