Recommended Lead-free Wave Soldering Curve (DIP-TYP)
Refer to the provided diagram for recommended soldering parameters. Adjustments may be necessary based on specific equipment and process conditions.
Soldering Iron (Rework)
- Hand soldering: Max 350 degrees, not exceeding 3 times.
- Avoid direct contact with the inductor body or wire during soldering.
- Hand soldering is not recommended.
Reminders for Using These Products
- Storage: Within 12 months, at 5~40C and 35~65% RH. Terminal solderability may deteriorate beyond this period.
- Environment: Avoid gas corrosive environments (salt, acid, alkali).
- Handling: Avoid direct contact with terminals due to hand oils affecting solderability. Handle carefully to prevent damage from dropping.
- Terminal Bending: Do not excessively bend terminals to prevent wire fracture.
- Cleaning: Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Keep away from magnets or magnetic objects.
- Preheating: Preheat components before soldering. Ensure temperature difference between solder and chip is within 150C.
- Soldering Correction: Perform corrections within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Self Heating: Account for self-heating when power is applied in thermal design.
- Non-Magnetic Shield Type: Careful layout is needed on the PCB to prevent malfunctions due to magnetic interference.
