Usage Precautions
- Allow flux to dry thoroughly before soldering to prevent quality degradation.
- Do not immerse trimmer potentiometers in solvents. Contact for cleaning instructions if necessary.
- Avoid applying excessive force to terminals, center terminals, or sliders during PCB insertion and assembly to prevent deformation and poor contact. Pay special attention to the slider area on open types.
- Store away from high/low temperatures, high humidity, and corrosive gases. Exercise extra caution for long-term storage.
- Be mindful of the stacking pressure on products during storage.
- Implement a First-In, First-Out (FIFO) inventory management system.
