Soldering and Cleaning Recommendations:

Through-hole displays are incompatible with reflow soldering
Mild "no-clean" fluxes recommended for soldering
Components should be cleaned with water only, avoiding harsh organic solvents
Cleaning should occur at room temperature, not exceeding one minute
Mounting and Circuit Design Notes:

Do not bend component leads by hand without proper tools
Ensure terminal pitch matches substrate board's hole pitch
Place component at least 5mm from PCB edge to avoid heat damage during soldering
Use protective current-limiting resistors for LED operation within specified range
Design driving circuit to protect against reverse voltages and transient spikes
