Precautions:
Lead Forming
• The leads of an LED lamp may be preformed or cut to
• If lead forming is required before soldering, care must
• For better control, it is recommended to use proper tool
Soldering Conditions
• Care must be taken during PCB assembly and soldering
• The closest manual soldering distance of the soldering
• Recommended soldering conditions:
• Wave soldering parameter must be set and maintained
Notes:

induced into the LED package. Otherwise, cut the leads
of LED to length after soldering process at room

advised to take extra precaution during wave soldering to ensure
that the maximum wave temperature is not exceeding 250 C.
Overstressing the LED during soldering process might cause
premature failure to the LED due to delamination.
