Precautions for Use
- Ensure flux is fully dried before soldering to prevent quality degradation. Pay attention to flux application amount.
- Do not immerse potentiometers in solvents. Contact manufacturer for cleaning procedures.
- Avoid applying excessive force to terminals, center terminals, or wiper contacts after insertion into PCBs and assembly, as this can cause deformation and poor contact. Exercise extra caution with open-type potentiometers, especially around the wiper mechanism.
- Store potentiometers away from high/low temperatures, high humidity, and corrosive gases. Exercise extra caution for long-term storage.
- Be mindful of stacking pressure on stored products.
- Implement a First-In, First-Out (FIFO) inventory management system for stock.
