T-1¾ (5 mm) Precision Optical Performance
AlInGaP LED Lamps
Description
Features
These precision optical performance AlInGaP LEDs provide
superior light output for excellent readability in sunlight and
are extremely reliable. AlInGaP LED technology provides
extremely stable light output over long periods of time.
Precision optical performance lamps use the aluminum
indium gallium phosphide (AlInGaP) technology.
These LED lamps are tinted, diffused, T-1¾ packages
incorporating second-generation optics producing
well-defined radiation patterns at specific viewing cone
angles.
The high maximum LED junction temperature limit of
+130°C enables high temperature operation in bright
sunlight conditions.
These lamps are available in two package options to give
the designer flexibility with device mounting.

Precautions
Lead Forming
The leads of an LED lamp may be preformed or cut to
length prior to insertion and soldering on PC board.
For better control, use the proper tool to precisely form
and cut the leads to the applicable length rather than
doing it manually.
If manual lead cutting is necessary, cut the leads after
the soldering process. The solder connection forms a
mechanical ground that prevents mechanical stress
due to lead cutting from traveling into the LED package.
Perform this action for the hand solder operation,
because the excess lead length also acts as small heat
sink.
Soldering and Handling
Take care during the PCB assembly and soldering
process to prevent damage to the LED component.
LED component may be effectively hand soldered to
the PCB; however, do this only under unavoidable
circumstances, such as rework. The closest manual
soldering distance of the soldering heat source
(soldering iron's tip) to the body is 1.59 mm.
1.59 mm
Soldering the LED using a soldering iron tip closer than
1.59 mm might damage the LED.
Apply ESD precautions on the soldering station and
personnel to prevent ESD damage to the LED
component, which is ESD sensitive. Refer to Broadcom
application note AN 1142 for details. Use a soldering
iron used with a grounded tip to ensure that
electrostatic charge is properly grounded.
The following table shows the recommended soldering
condition.

a. The preceding conditions refer to measurement with a
thermocouple mounted at the bottom of the PCB.
b. Use only bottom preheaters to reduce thermal stress
experienced by the LED.
Set and maintain wave soldering parameters according
to the recommended temperature and dwell time.
Perform daily checks on the soldering profile to ensure
that it always conforms to the recommended soldering
conditions.
NOTE:
1. PCBs with different sizes and designs (component
density) have different heat mass (heat capacity). This
might cause a change in temperature experienced by
the board if the same wave soldering setting is used. So,
recalibrate the soldering profile again before loading a
new type of PCB.
2. The Broadcom high brightness LEDs use high-efficiency
LED dies with single wire bond as shown in the following
figure. Take extra precautions during wave soldering to
ensure that the maximum wave temperature does not
exceed 250°C and the solder contact time does not
exceed 3 seconds. Overstressing the LED during the
soldering process might cause premature failure to the
LED due to delamination.

LED Configuration
If PCB board contains both through-hole (TH) LED and
other surface mount components, solder the surface
mount components on the top side of the PCB. If
surface mount must be on the bottom side, solder these
components using reflow soldering prior to insertion the
TH LED.
The following table shows the recommended PC board
plated through-holes (PTH) size for LED component
leads.
CATHODE
LED Component
Lead Size
AllnGaP Device
NOTE: The electrical connection between the bottom surface of
the LED die and the lead frame is achieved through conductive
paste.
Any alignment fixture that is being applied during wave
soldering should be loosely fitted and should not apply
weight or force on LED. Use nonmetal material
because it absorbs less heat during wave soldering
process.
At elevated temperatures, LED is more susceptible to
mechanical stress. Therefore, allow the PCB to cool
down to room temperature prior to handling, which
includes the removal of the alignment fixture or pallet.

Oversizing the PTH can lead to a twisted LED after
clinching. On the other hand, undersizing the PTH can
cause difficulty inserting the TH LED.
Refer to application note AN5334 for more information
about soldering and handling of high-brightness TH LED
lamps.
