Precautionary Notes
cleaning, rub the surface gently without putting too
much pressure on the silicone. Ultrasonic cleaning is
not recommended.
Reflow Soldering
Do not perform reflow soldering more than twice.
Observe necessary precautions of handling
moisture-sensitive devices as stated in Handling of
Moisture-Sensitive Devices.
Handling of Moisture-Sensitive Devices
Do not apply any pressure or force on the LED during
reflow and after reflow when the LED is still hot.
This product has a Moisture Sensitive Level 3 rating per
JEDEC J-STD-020. Refer to Broadcom Application Note
AN5305, Handling of Moisture Sensitive Surface Mount
Devices, for additional details and a review of proper
handling procedures.

Before use:
255 – 260°C
3°C/SEC. MAX.
An unopened 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 humidity indicator
card (HIC) indicates that baking is not required, it is
safe to reflow the LEDs per the original MSL rating.

150°C
3°C/SEC. MAX.
Do not open the MBB prior to assembly (for example,
for IQC). If unavoidable, MBB must be properly
resealed with fresh desiccant and HIC. The exposed
duration must be taken in as floor life.
60 – 120 SEC.
100 SEC. MAX.

Control after opening the MBB:
Handling Precautions
Read the HIC immediately upon opening of MBB.
Keep the LEDs at <30°/60% RH at all times, and
complete all high temperature-related processes,
including soldering, curing, or rework within 168 hours.
The encapsulation material of the LED is made of silicone
for better product reliability. Compared to epoxy
encapsulant, which is hard and brittle, silicone is softer and
flexible. Observe special handling precautions during
assembly of silicone encapsulated LED products. Failure to
comply might lead to damage and premature failure of the
Control for unfinished reel:
Store unused LEDs in a sealed MBB with desiccant or a
desiccator at <5% RH.

LED. Refer to Broadcom Application Note AN5288,
Silicone Encapsulation for LED: Advantages and Handling
Control of assembled boards:
Precautions, for additional information.
If the PCB soldered with the LEDs is to be subjected to other
high-temperature processes, store the PCB in a sealed
MBB with desiccant or desiccator at <5% RH to ensure that
all LEDs have not exceeded their floor life of 168 hours.
Do not poke sharp objects into the silicone encapsulant.
Sharp objects, such as tweezers or syringes, might
apply excessive force or even pierce through the
silicone and induce failures to the LED die or wire bond.
Do not touch the silicone encapsulant. Uncontrolled
force acting on the silicone encapsulant might result in
excessive stress on the wire bond. Hold the LED only
by the body.
Baking is required if the following conditions exist:
The HIC indicator indicates a change in color for 10%
and 5%, as stated on the HIC.
The LEDs are exposed to conditions of >30°C/60% RH
at any time.
Do not stack assembled PCBs together. Use an
appropriate rack to hold the PCBs.
The LED's floor life exceeded 168 hours.
The surface of silicone material attracts dust and dirt
easier than epoxy due to its surface tackiness. To
remove foreign particles on the surface of silicone, use
a cotton bud with isopropyl alcohol (IPA). During
The recommended baking condition is: 60°C ± 5ºC for
20 hours. Baking can only be done once.
