Recommended Reflow Soldering Curve
Refer to the provided graph for recommended reflow conditions. Users should adjust and confirm conditions based on their specific environment and equipment.
Usage Reminders
- Storage: Within 12 months, under 5~40C and 35~65% RH.
- Environment: Avoid gas corrosive environments (salt, acid, alkali).
- Handling: Avoid direct contact with terminals due to hand oils. Handle with care to prevent damage.
- Soldering: Preheat components before soldering. Ensure temperature difference between solder and chip is within 150C. Post-mounting corrections should be within specifications to avoid performance degradation.
- Thermal Design: Account for self-heating when power is on.
- Magnetic Fields: Do not expose to magnets or magnetic fields.
- Cleaning: Do not rinse coils; contact manufacturer if cleaning is necessary.
