Mounting and Design Considerations:

Through-hole display mounting method
Avoid bending component leads by hand; use proper tools
Ensure terminal pitch matches substrate board's hole pitch
Place component at least 5mm from PCB edge to prevent heat damage
Design circuit with protective resistors and reverse voltage protection
Recommended Soldering Profile:

Pre-heat temperature of 105°C or less
Solder bath temperature of 260°C for 3-5 seconds
Avoid stress on epoxy resin above 85°C
Use SAC 305 solder alloy
PCB top-surface temperature below 105°C during soldering
Cleaning Instructions:

Use mild "no-clean" fluxes for soldering
Wash components with water only if cleaning is required
Avoid harsh organic solvents that may damage plastic parts
Clean at room temperature and do not wash for more than one minute
Remove excess moisture with forced-air drying immediately
