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