Moisture Sensitivity
This product is qualified as Moisture Sensitive Level 2a per
Jedec J-STD-020. Precautions when handling this moisture
sensitive product is important to ensure the reliability of
the product. Do refer to Avago Application Note AN5305
Handling of Moisture Sensitive Surface Mount Devices for
details.
A. Storage before use
– Unopen moisture barrier bag (MBB) can be stored at
<40°C/90%RH for 12 months. If the actual shelf life
has exceeded 12 months and the HIC indicates that
baking is not required, then it is safe to reflow the
LEDs per the original MSL rating.
– It is not recommended to open the MBB prior to
assembly (e.g. for IQC).
B. Control after opening the MBB
– The humidity indicator card (HIC) shall be read
immediately upon opening of MBB.
– The LEDs must be kept at <30°C/60%RH at all time
and all high temperature related process including
soldering, curing or rework need to be completed
within 672 hours.
C. Control for unfinished reel
– For any unuse LEDs, they need to be stored in sealed
MBB with desiccant or desiccator at <5%RH.
D. Control of assembled boards
– If the PCB soldered with the LEDs is to be subjected to
other high temperature processes, the PCB need to
be stored in sealed MBB with desiccant or desiccator
at <5%RH to ensure no LEDs have exceeded their
floor life of 672 hours.
E. Baking is required if:
– “10%” is Not blue and “5%” HIC indicator turns pink.
– The LEDs are exposed to condition of >30°C/60%RH
at any time.
– The LEDs floor life exceeded 672 hours.
Recommended baking condition: 60±5°C for 20 hours.
Handling Precaution
The encapsulation material of the product is made of
silicone for better reliability of the product. As silicone is
a soft material, please do not press on the silicone or poke
a sharp object onto the silicone. These might damage the
product and cause premature failure. During assembly
of handling, the unit should b e held on the body only.
Please refer to Avago Application Note AN 5288 for detail
information.
