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