Usage Precautions
- Soldering: Ensure flux is completely dry before soldering to prevent quality degradation. Pay attention to flux application amount.
- Cleaning: Do not immerse the trimmer potentiometer in solvents. Contact the manufacturer for cleaning procedures if necessary.
- Handling: Avoid applying excessive force to terminals, center terminals, or wiper contacts during PCB insertion and assembly to prevent deformation and contact issues, especially with open-type designs.
- Storage: Store away from high/low temperatures, high humidity, and corrosive gases. Exercise extra caution for long-term storage.
- Stacking: Be mindful of stacking pressure on the products during storage.
- Inventory Management: Implement a First-In, First-Out (FIFO) system for managing inventory.
