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 Conditions
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 1.59
mm below the body (encapsulant epoxy) for those
parts without standoff.
Recommended soldering conditions:
Wave Soldering
Pre-heat Temperature
105°C Max.
Pre-heat Time
30 sec Max.
Peak Temperature
250°C Max.
Dwell Time
3 sec Max.
Manual Solder
Dipping
260°C Max.
5 sec Max.
Wave soldering parameter must be set and maintained
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 ther-
mal stresses to LED components when heated. There-
fore, the soldered PCB must be allowed to cool to room
temperature, 25°C, before handling.
Special attention must be given to board fabrication,
solder masking, surface plating and lead holes size and
component orientation to assure solderability.
