Usage Precautions
Soldering	Ensure flux is thoroughly dried before soldering. Be mindful of flux application amount.
Cleaning	Avoid immersing in solvents. Contact manufacturer for cleaning procedures if necessary.
Handling	Do not apply excessive force to terminals, center terminals, or sliders after PCB insertion and assembly to prevent deformation and poor contact, especially on open-type models.
Storage	Avoid high/low temperatures, high humidity, and corrosive gas environments. Pay extra attention for long-term storage. Avoid stacking products excessively. Implement FIFO (First-In, First-Out) inventory management.
