Soldering and Cleaning Guidelines:

Use mild "no-clean" fluxes for soldering.
For cleaning, use water only and avoid harsh organic solvents.
Clean at room temperature and limit wash time to one minute.
After washing with water, use forced-air drying to remove excess moisture promptly.
Mounting and Circuit Design Notes:

Avoid bending 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 to avoid damage from heat.
Design circuits with protective current-limiting resistors and consider reverse voltage protection.
Precautionary Notes:

Refer to the latest datasheet for updated specifications before production.
Operate products within the environmental and electrical limits specified.
For special processes like potting, consult with Kingbright representatives.
