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 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
thermal stresses to LED components when heated.
Therefore, 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.
• Recommended PC board plated through hole sizes for
LED component leads:
