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 or
handling, the unit should be held on the body only. Please
refer to Avago Application Note AN 5288 for detail infor-
mation.
Moisture Sensitivity
This product is qualified as Moisture Sensitive Level 2 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
7
– Unopen moisture barrier bag (MBB) can be stored at
– It is not recommended to open the MBB prior to
<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.
assembly (e.g. for IQC).
B. Control after opening the MBB
C. Control for unfinished reel
D. Control of assembled boards
E. Baking is required if:
Recommended baking condition: 60±5°C for 20 hours.
– The humidity indicator card (HIC) shall be read
– The LEDs must be kept at <30°C/60% RH at all time
– For any unused LEDs, they need to be stored in
– If the PCB soldered with the LEDs is to be subjected to
– “60%” HIC indicator is NOT Green.
– The LEDs are exposed to condition of >30°C/60% RH
– The LEDs floor life exceeded 1 year.
immediately upon opening of MBB.
and all high temperature related process including
soldering, curing or rework need to be completed
within 1 year.
sealed MBB with desiccant or desiccator at <5% RH
in order to stop the floor life. Otherwise, the floor
life will continue and precaution should be taken to
ensure it does not exceed 1 year.
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 1 year.
