Recommended Reflow Soldering Curve
The recommended reflow conditions are set according to the manufacturer's soldering equipment. Users should adjust and confirm conditions based on their specific environment and equipment.
Reminders for Using These Products
- Storage period is within 12 months under conditions (temperature: 5~40C, humidity: 35~65% RH or less).
- Do not use or store in locations with gas corrosion (salt, acid, alkali, etc.).
- Avoid direct contact with terminals by bare hands due to oil secretions affecting soldering.
- Handle products carefully to prevent damage from dropping or improper removal.
- Do not bend terminals with excessive stress to avoid wire fracture.
- Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Do not expose products to magnets or magnetic fields.
- Preheat components before soldering; the temperature difference between solder and chip should not exceed 150C.
- Soldering corrections after mounting should be within specified conditions; overheating can cause issues.
- Allow sufficient margin for thermal design due to self-heating when power is ON.
- For non-magnetic shield types, careful coil layout is needed to prevent malfunctions due to magnetic interference.
