Precautions:
Lead Forming:
• The leads of an LED lamp may be preformed or cut to
• If lead forming is required before soldering, care must be
• It is recommended that tooling made to precisely form
Soldering Condition:
• Care must be taken during PCB assembly and soldering
• The closest LED is allowed to solder on board is 1.59mm
• Recommended soldering condition:
