LED Lamps
Overview
The Broadcom® 5V and 12V series lamps contain an
integral current limiting resistor in series with the LED. This
allows the lamp to be driven from a 5V/12V source without
an external current limiter.
Features
The diffused lamps provide a wide off-axis viewing angle.
The T-1¾ lamps are provided with sturdy leads suitable for
wire wrap applications. The T-1¾ lamps may be front panel
mounted by using the HLMP-0103 clip and ring.

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 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.
Use this method for the hand soldering 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.
The LED component may be effectively hand soldered
to the PCB. However, do this 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. Soldering
the LED using soldering iron tip closer than 1.59 mm
might damage the LED.
1.59 mm
Apply ESD precautions on the soldering station and
personnel to prevent ESD damage to the LED
component that is ESD sensitive. Refer to Broadcom
application note AN 1142 for details. The soldering iron
used must have a grounded tip to ensure electrostatic
charge is properly grounded.

a. The preceding conditions refer to measurement with a
thermocouple mounted at the bottom of the PCB.
b. Use only bottom pre-heaters to reduce thermal stress
experienced by LED.
Broadcom
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 size and design (component
density) will have a different heat mass (heat capacity).
This might cause a change in temperature experienced
by the board if the same wave soldering setting is used.
Therefore, recalibrate the soldering profile again before
loading a new type of PCB.
2. 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 3s.
Overstressing the LED during the soldering process
might cause premature failure to the LED due to
delamination.
Loosely fit any alignment fixture that is being applied
during wave soldering and do not apply weight or force
on the LED. Use non-metal material because it will
absorb less heat during the wave soldering process.
At elevated temperature, the LED is more susceptible
to mechanical stress. Therefore, allow the PCB to cool
down to room temperature prior to handling, which
includes removal of alignment fixture or pallet.
If the PCB board contains both through-hole (TH) LED
and other surface-mount components, solder surfacemount components on the top side of the PCB. If the
surface mount must be on the bottom side, solder these
components using reflow soldering prior to the insertion
of the TH LED.
The recommended PC board plated through holes
(PTH) size for LED component leads follows:
LED Component Lead Size
Lead size (typ.) 0.45 × 0.45 mm
(0.018 × 0.018 in.)
Dambar shear0.65 mm

(0.026 in.)

0.98 to 1.08 mm
(0.039 to 0.043 in.)
1.05 to 1.15 mm
(0.041 to 0.045 in.)
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 AN1027 for more information
about soldering and handling of TH LED lamps.
