Description
Features
®
The Broadcom ALMD-Ex1E/2E series is essentially like a
Using high brightness AlInGaP material
conventional high brightness through holes LED in the form
of surface mount device. It can be assembled using
common SMT assembly processes and are compatible with
industrial reflow soldering processes.
Available in Red and Amber
– Red – AlInGaP 621 nm
– Amber – AlInGaP 590 nm
Typical viewing angle: 15° and 23°
JEDEC MSL 3
The LEDs are made with an advanced optical grade epoxy
for superior performance in outdoor sign applications. For
easy pick and place assembly, the LEDs are shipped in tape
and reel. Every reel is shipped from a single intensity and
color bin for better uniformity.
Compatible with industrial reflow soldering process
Tinted
Applications
Variable message signs
CAUTION! The LEDs are ESD sensitive per ANSI/ESDA/JEDEC JS-001. Please observe appropriate precautions during
handling and processing. Refer to Application Note AN-1142 for additional details.
CAUTION! Customers should always keep the LED in the moisture barrier bag (MBB) with < 5% RH when not in use
because prolonged exposure to the environment might cause the silver-plated leads to tarnish or rust, which
might cause difficulties in soldering.

Soldering
Recommended reflow soldering condition.
Figure 16: Leaded Reflow Soldering
Figure 17: Lead-Free Reflow Soldering
1. Do not perform reflow soldering more than twice.
Observe necessary precautions of handling moisture
sensitive devices as stated in the next section.
3. Do not apply any pressure or force on the LED during
reflow and after reflow while the LED is still hot.
4. Use reflow soldering to solder the LED. Use hand
soldering for rework only if unavoidable but must be
strictly controlled for the following conditions:
2. Recommended board reflow direction.
Figure 18: Recommended Board Reflow Direction
– Soldering iron tip temperature = 320°C maximum
– Soldering duration = 3 seconds maximum
– Number of cycles = 1 only
– Power of soldering iron = 50W maximum
5. Do not touch the LED body with a hot soldering iron
except when soldering the terminals because it might
damage the LED.
6. For de-soldering, use an appropriate double-head
soldering iron. Confirm beforehand whether the
functionality and performance of the LED is affected by
hand soldering.

Precautionary Notes
Control for unfinished reel:
Handling Precautions
Store unused LEDs in a sealed MBB with desiccant or
desiccator at <5% RH.
For automated pick-and-place, Broadcom has tested the
following nozzle size made with a urethane material to work
well with this LED. However, due to the possibility of
variations in other parameters, such as pick-and-place
machine, maker and model, and other settings of the
machine, verify the selected nozzle before using it.
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.
Figure 19: Nozzle Size
Baking is required if the following conditions exist:
The HIC indicator is not BROWN at 10% and is AZURE
at 5%.
The LEDs are exposed to conditions of >30°C/60% RH
at any time.
The LED floor life exceeded 168 hours.
The recommended baking condition is: 60°C ± 5ºC for 20
hours. Baking should only be done once.
Storage:
The soldering terminals of these Broadcom LEDs are silver
plated. If the LEDs are exposed in ambient environments for
too long, the silver plating might oxidize; thus affecting their
solderability performance. As such, keep unused LEDs in a
sealed MBB with desiccant or in desiccator at <5% RH.
Handling of Moisture Sensitive Devices
This product has a Moisture Sensitive Level 3 rating per
JEDEC J-STD-020. Refer to Application Note AN-5305,
Handling of Moisture Sensitive Surface Mount Devices, for
additional details and a review of proper handling
procedures.
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
Before use:
You can 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, then it
is safe to reflow the LEDs per the original MSL rating.
recommended to ensure consistent performance.
LEDs exhibit slightly different characteristics at different
drive currents, which might result in larger performance
variations (that is, intensity, wavelength, and forward
voltage). Set the application current as close as
Do not open the MBB prior to assembly (for example,
for IQC).
possible to the test current to minimize these variations.
The LED is not intended for reverse bias. Use other
appropriate components for such purposes. When
driving the LED in matrix form, it is critical to ensure that
the reverse bias voltage does not exceed the allowable
limit of the LED.
Control after opening the MBB:
Read the HIC immediately upon opening the MBB.
Keep the LEDs at <30°C/60% RH at all times, and
complete all high temperature-related processes,
including soldering, curing, or rework, within 168 hours.
Avoid rapid changes in ambient temperatures,
especially in high-humidity environments, because this
situation causes condensation on the LED.

High Brightness SMT Round Red, Amber LED Lamps
If the LED is intended to be used in outdoor or harsh
environments, protect the LED leads with a suitable
potting material against damages caused by rain water,
oil, corrosive gases and so on. Use a louver or a shade
to reduce direct sunlight on the LEDs.
Eye Safety Precautions
LEDs might pose optical hazards when in operation. Do not
look directly at an operating LED as it might be harmful to
the eyes. For safety reasons, use appropriate shielding or
personal protective equipments.
The number of reflow cycles and reflow temperature
conditions used might affect the optical characteristics
of the LED. Use LEDs with the same number of reflow
cycles and same reflow temperature conditions within
the same finished product.
