| 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. |
