Recommended Lead-free Wave Soldering Curve (DIP-Type)
Note: The recommended wave soldering curve is a reference. Adjust and confirm according to user's environment/equipment.
Soldering Iron (Rework)
- Hand soldering should not exceed 350 degrees and 3 times.
- Avoid contacting the inductor body or wire during soldering.
- Hand soldering is not recommended.
Usage Precautions
- Storage: Within 12 months under conditions of 5~40C and 35~65% RH. Solderability may deteriorate beyond this period.
- Environment: Avoid use and storage in corrosive gas environments (salt, acid, alkali, etc.).
- 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.
- Magnetism: Keep away from magnets or magnetic objects.
- Preheating: Preheat components before soldering; temperature difference between solder and chip should not exceed 150C.
- Soldering Correction: Perform soldering corrections within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Self-heating: Allow for sufficient thermal design due to self-heating when power is on.
- Non-magnetic Shield Type: Careful layout is required on the PCB to prevent malfunctions due to magnetic interference.
