Usage Precautions
- Ensure flux is completely dry before soldering to prevent quality degradation. Pay attention to flux application amount.
- Do not immerse trimmer potentiometers in solvents. Contact manufacturer for cleaning procedures if necessary.
- Avoid applying excessive force to terminals, center terminals, or wiper elements during PCB insertion and assembly to prevent deformation and poor contact. Exercise extra caution with open-type models.
- Store away from high/low temperatures, high humidity, and corrosive gases. Exercise particular care for long-term storage.
- Be mindful of stacking limits for stored products.
- Implement a First-In, First-Out (FIFO) inventory management system.
