Description
Features
®
The Broadcom ASMW-LG00 and ASMW-LM00
High reliability package with enhanced silicone resin
encapsulation
surface-mount LEDs use InGaN chip technology with
superior package design to enable them to produce higher
light output with better flux performance. They can be driven
at high current and are able to dissipate heat more efficiently
resulting in better performance with higher reliability.
Moisture sensitivity level 3
Available in green and deep blue colors
Low package profile and large emitting area
Enhanced corrosion resistance
These LEDs operate under a wide range of environmental
conditions, making them ideal for various applications,
applications including fluorescent replacement,
under-cabinet lighting, retail display lighting and panel
lights.
Applications
Specialty and architectural lighting
Gaming and vending machine backlighting
Industrial lighting; for example, tower light
Industrial equipment indicator
To facilitate easy pick-and-place assembly, the LEDs are
packed in tape and reel. Every reel is shipped in single flux
and color bin to provide close uniformity.
CAUTION! This LED is Class 1A ESD sensitive per ANSI/ESDA/JEDEC JS-001. Observe appropriate precautions during
handling and processing. Refer to Application Note AN-1142 for additional details.

Precautionary Notes
Soldering
Handling Precautions
Do not perform reflow soldering more than twice.
Observe necessary precautions of handling
moisture-sensitive devices as stated in the following
section.
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
LED. Refer to Broadcom Application Note AN5288, Silicone
Encapsulation for LED: Advantages and Handling
Precautions, for additional information.
Do not apply any pressure or force on the LED during
reflow and after reflow when the LED is still hot.
Use reflow soldering to solder the LED. Use hand
soldering only for rework if unavoidable, but it must be
strictly controlled to following conditions:
– Soldering iron tip temperature = 315°C maximum
– Soldering duration = 3 seconds maximum
– Number of cycles = 1 only
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.
– Power of soldering iron = 50W maximum
Do not touch the LED package body with the soldering
iron except for the soldering terminals, because it may
cause damage to the LED.
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.
Confirm beforehand whether the functionality and
performance of the LED is affected by soldering with
hand soldering.
Do not stack assembled PCBs together. Use an
appropriate rack to hold the PCBs.
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
cleaning, rub the surface gently without putting too
much pressure on the silicone. Ultrasonic cleaning is
not recommended.

For automated pick-and-place, Broadcom has tested a
nozzle size with an outer diameter of 3.5 mm to work
with this LED. However, due to the possibility of
variations in other parameters, such as pick-and-place
machine maker/model, and other settings of the
machine, verify that the selected nozzle will not cause
damage to the LED.

Storage
Handling of Moisture-Sensitive Devices
The soldering terminals of these Broadcom LEDs are silver
plated. If the LEDs are exposed in an ambient environment
for too long, the silver plating might be oxidized, thus
affecting its solderability performance. As such, keep
unused LEDs in a sealed MBB with desiccant or in a
desiccator at <5% RH.
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
Store an unopened moisture barrier bag (MBB) 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.
Application Precautions
The drive current of the LED must not exceed the
maximum allowable limit across temperature as stated
in the data sheet. Constant current driving is
recommended to ensure consistent performance.
Do not open the MBB prior to assembly (for example,
for IQC). If unavoidable, properly reseal the MBB with
fresh desiccant and HIC. The exposed duration must be
taken in as floor life.
The circuit design must cater to the entire range of
forward voltage (V ) of the LEDs to ensure the intended
F
drive current can always be achieved.
The LED exhibits slightly different characteristics at
different drive currents, which may result in a larger
variation of performance (such as intensity, wavelength,
and forward voltage). Set the application current as
close as possible to the test current to minimize these
variations.
Control after opening the MBB
Read the HIC immediately upon opening the MBB.
Keep the LEDs at <30°/60% RH at all times, and
complete all hightemperature-related processes,
including soldering, curing, or rework, within 168 hours.
The LED is not intended for reverse bias. Use other
appropriate components for such purposes. When
driving the LED in matrix form, ensure that the reverse
bias voltage does not exceed the allowable limit of the
LED.
Control for unfinished reel
Store unused LEDs in a sealed MBB with desiccant or a
desiccator at <5% RH.
This LED is designed to have enhanced gas corrosion
resistance. Its performance has been tested according
to the following conditions:
Control of assembled boards
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.
– IEC 60068-2-43: 25°C/75% RH, H S 15 ppm,
2
21 days.
– IEC 60068-2-42: 25°C/75% RH, SO 25 ppm,
2
21 days.
– IEC 60068-2-60: 25°C/75% RH, SO 200 ppb, NO
Baking is required if the following conditions exist
2
2
200 ppb, H S 10 ppb, Cl 10 ppb, 21 days.

2
The HIC indicator indicates a change in color for 10%
and 5%, as stated on the HIC.
Because the actual application might not be exactly
similar to the test conditions, verify that the LED will not
be damaged by prolonged exposure in the intended
environment.
The LEDs are exposed to conditions of >30°C/60% RH
at any time.
The LED's floor life exceeded 168 hours.
Avoid rapid changes in ambient temperatures,
especially in high-humidity environments, because they
cause condensation on the LED.
The recommended baking condition is: 60°C ± 5°C for
20 hours.
If the LED is intended to be used in a harsh or an
outdoor environment, protect the LED by means of a
protective cover against damages caused by rain water,
water, dust, oil, corrosive gases, external mechanical
stresses, and so on.
Baking can only be done once.
