Usage Precautions
- Ensure flux is fully dried before soldering to prevent quality degradation. Pay attention to the amount of flux applied.
- Do not immerse trimmer potentiometers in solvents. Contact us if cleaning is necessary.
- Avoid applying excessive force to terminals, center pins, or wiper contacts during PCB insertion and assembly to prevent deformation and poor contact. Exercise extra caution with open-type designs.
- Store away from high/low temperatures, high humidity, and corrosive gases. Pay special attention to long-term storage.
- Avoid stacking products excessively during storage.
- Implement a First-In, First-Out (FIFO) inventory management system.
