Users should adjust and confirm reflow conditions based on their specific environment and equipment. The recommended curve is provided as a guideline.
Reminders for Using These Products
- Storage: Within 12 months, under conditions of 5~40C and 35~65% RH.
- Environment: Avoid gas corrosive environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals to prevent solderability issues. Handle with care to prevent damage.
- Terminal Bending: Do not excessively bend terminals to avoid 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; temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Perform within specified conditions; overheating may cause damage.
- Thermal Design: Account for self-heating when power is on.
- Non-shielded Type: Careful coil placement on the PCB is required to prevent malfunction due to magnetic interference.
