SMD LED STORAGE AND HANDLING PRECAUTIONS
<Storage
Conditions before Opening a Moisture-Barrier Aluminum Bag>
・
Before opening a moisture-barrier aluminum bag, please store it at <30ºC, <60%RH. Please
note that the maximum shelf life is 12 months under these conditions.
<Storage
Conditions after Opening a Moisture-Barrier Aluminum Bag>
・
After opening a moisture-barrier aluminum bag, store the aluminum bag and silica gel in a
desiccator.
・After
opening the bag, please solder the LEDs within 72 hours in a room with 5 - 30ºC, <50%RH.
・Please
put any unused, remaining LEDs and silica gel back in the same aluminum bag and then
vacuum-seal the bag.
・It
is recommended to keep the re-sealed bag in a desiccator at <30%RH.
<Notes
about Re-sealing a Moisture-Barrier Aluminum Bag>
・When
vacuum-sealing an opened aluminum bag, if you find the moisture-indicator of the silica gel
has changed to pink from blue (indicating a relative humidity of 30 % or more), please do not use the
unused LEDs, the aluminum bag, or the silica gel.
<Notes
about Opening a Re-sealed Moisture-Barrier Aluminum Bag>
・When
opening a vacuumed and re-sealed aluminum bag in order to use the remaining LEDs stored
in the bag, if you find that the moisture-indicator of the silica has changed to pink, please do not
use the LEDs.
※The
72-hour- long floor life does not include the time while LEDs are stored in the moisture-barrier
aluminum bag.
However, we strongly recommend to solder the LEDs as soon as possible after opening the
aluminum bag.
