Handling Precautions:

Use wrist bands or anti-electrostatic gloves when handling LEDs.
All devices, equipment, and machinery must be electrically grounded.
Exceeding recommended conditions may result in severe light degradation or premature failure.
Soldering Profile:

Pre-heat temperature: 105°C or less.
Maximum solder bath temperature: 260°C for 3-5 seconds.
Recommended solder alloy: SAC 305.
PCB top-surface temperature during wave soldering should be kept below 105°C.
Cleaning Instructions:

Use mild "no-clean" fluxes for soldering.
Wash components with water only; avoid harsh organic solvents.
Clean at room temperature and limit washing time to one minute.
Remove excess moisture with forced-air drying immediately after washing.
Mounting Method:

Do not bend component leads by hand; use proper tools.
Ensure terminal pitch matches the substrate board's hole pitch.
Place components at least 5mm from the edge of the PCB.
Circuit Design Notes:

Use protective current-limiting resistors for operating LEDs within the specified range.
Design the driving circuit to protect against reverse voltages and transient spikes.
Choose the safe operating current considering the maximum ambient temperature.
Avoid prolonged reverse bias to prevent metal migration and short circuits.
