HLMP-FW00 Datasheet, PDF (5/6 Pages) AVAGO TECHNOLOGIES LIMITED – 5mm Flat Top InGaN White LED Lamp

Precautions:
Lead Forming:
• The leads of an LED lamp may be preformed or cut to
length prior to insertion and soldering into PC board.
• If lead forming is required before soldering, care must
be taken to avoid any excessive mechanical stress
induced to LED package. Otherwise, cut the leads
of LED to length after soldering process at room
temperature. The solder joint formed will absorb the
mechanical stress of the lead cutting from traveling to
the LED chip die attach and wirebond.
• It is recommended that tooling made to precisely form
and cut the leads to length rather than rely upon hand
operation.
Soldering Condition:
• Care must be taken during PCB assembly and soldering
process to prevent damage to LED component.
• The closest LED is allowed to solder on board is
1.59mm below the body (encapsulant epoxy) for those
parts without standoff.
• Recommended soldering condition:

• Wave soldering parameter must be set and maintain
according to recommended temperature and dwell
time in the solder wave. Customer is advised to
periodically check on the soldering profile to ensure
the soldering profile used is always conforming to
recommended soldering condition.
• If necessary, use fixture to hold the LED component
in proper orientation with respect to the PCB during
soldering process.
• Proper handling is imperative to avoid excessive
thermal stresses to LED components when heated.
Therefore, the soldered PCB must be allowed to cool
to room temperature, 25ûC before handling.
• Special attention must be given to board fabrication,
solder masking, surface plating and lead holes size
and component orientation to assure solderability.
• Recommended PC board plated through holes
