Usage Precautions
- Ensure flux is thoroughly dry before soldering to prevent quality degradation. Pay attention to the amount of flux applied.
- Do not immerse potentiometers in solvents. Contact for cleaning instructions if necessary.
- Avoid applying excessive force to terminals, sliders, or wiper parts during PCB insertion and assembly to prevent deformation and poor contact. Exercise caution with open-type designs, especially the wiper area.
- Store away from high/low temperatures, high humidity, and corrosive gases. Special attention is required for long-term storage.
- Be mindful of stacking pressure on stored products.
- Implement a First-In, First-Out (FIFO) inventory management system.
