age the product and cause premature failure. During as-
sembly of handling, the unit should be held on the body
only. Please refer to Avago Application Note AN 5288 for
detail information.
Moisture Sensitivity
This product is quali ed 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 re ow
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 un nished 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 oor life of 672 hours.
E. Baking is required if:
- “10%” or “15%” HIC indicator turns pink.
- The LEDs are exposed to condition of >30°C / 60%
RH at any time.
- The LEDs oor life exceeded 672 hours.
Recommended baking condition: 60±5°C for 20 hours.
