PLCC-2 Surface Mount LED
Description
The Broadcom® ASMM-Cx03 Surface Mount LED is
packaged in the industry-standard PLCC-2 package and
has high-reliability performance designed to work under a
wide range of environmental conditions. This high-reliability
feature makes them ideally suited to be used for wide range
of applications.
The wide viewing angle at 120° makes these LEDs ideally
suited for panel, push button, or general backlighting in
office equipment, industrial equipment, and home
appliances. The flat top emitting surface makes it easy for
these LEDs to integrate with light pipes. With the built-in
reflector enhancing the light output intensity, these LEDs are
also suitable to be used as LED pixels in indoor electronic
signs.
To facilitate easy pick and place assembly, the LEDs are
packed in tape and feel form. Every reel is shipped in single
intensity and color bin to provide close uniformity.
Features
Industry-standard PLCC-2 package.
High-reliability LED package with enhanced silicone
resin encapsulation.
High brightness using AlGaAs, GaP, and AllnGaP dice
technologies.
Available in full selection of colors.
Wide angle viewing angle at 120°.
JEDEC MSL 3.
Applications
Electronic signs and signals.
Office automations, home appliances, and industrial
equipment.
– Front panel backlighting
– Push button backlighting
– Display backlighting
– Scanner lighting
CAUTION! This LED is ESD sensitive. Please observe appropriate precautions during handling and processing. Refer to
application note AN-1142 for additional details.

Precautionary Notes
Soldering
Figure 25: Recommended Board Reflow Direction
Do not perform reflow soldering more than twice.
Observe necessary precautions of handling moisturesensitive device as stated in the following section.
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 max.
– Soldering duration = 3 sec max.
– Number of cycles = 1 only.
– Power of soldering iron = 50W max.
Do not touch the LED package body with the soldering
iron except for the soldering terminals, as it may cause
damage to the LED.
Confirm beforehand whether the functionality and
performance of the LED is affected by soldering with
hand soldering.

Handling Precautions
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.

TIME
Broadcom
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.
Do not stack assembled PCBs together. Use an
appropriate rack to hold the PCBs.
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 OD 1.5 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.
