Usage Precautions
- Ensure flux is completely dry before soldering to prevent quality degradation.
- Do not immerse in solvents. Contact manufacturer for cleaning procedures.
- 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 types.
- Store away from high/low temperatures, humidity, and corrosive gases. Pay extra attention for long-term storage.
- Be mindful of stacking pressure on stored products.
- Practice First-In, First-Out (FIFO) inventory management.
