Recommended Wave Soldering Profile:

Through-hole displays are incompatible with reflow soldering.
Use mild "no-clean" fluxes for soldering.
Clean components with water only, avoiding harsh organic solvents.
Packing & Label Specifications:

Do not bend component leads by hand without proper tools.
Ensure the terminal pitch matches the substrate board's hole pitch during insertion.
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.
