Recommended Soldering Conditions (Reflow Soldering)
Soldering Conditions:
- Pre-heating: Temperature difference between solder and ferrite surface should be limited to 150 max.
- Cooling: Temperature difference between product surface and solvent after soldering should be limited to 100 max.
- Insufficient pre-heating may cause cracks on the ferrite, leading to product quality deterioration.
- Products should be soldered within the allowable range indicated by the profile curve. Excessive conditions may cause electrode corrosion.
- When soldering is repeated, allowable time is the accumulated time.
Manual Soldering
- Soldering Iron Temperature: 350 (Max)
- Power: 30W (Max)
- Soldering Time: < 5S (Take care not to apply the tip of the soldering iron to the terminal electrodes).
Cleaning Conditions
- Cleaning Temperature: 60 (Max)
- Cleaning Time: 1 minute (Min)
- Ultrasonic Output Power: 200W (Max)
Storage Requirements
- Storage Period: Within 1 year from the inspection date at the inductor company. If exceeding 1 year, solder ability should be checked before use.
- Storage Conditions:
- Warehouse Conditions: Temperature: -10 to +40, Relative Humidity: 30% to 70%.
- Prohibited Storage: Do not store in corrosive substances (sulfur, chlorine gas, acid) to prevent electrode oxidation and poor solderability.
- Placement: Store on a shelf to prevent influence from humidity and dust.
- Environment: Avoid heat shock, vibration, and direct sunlight.
- Packaging: Products should be stored under airtight packaged condition.
Usage Of ODS (Ozone Depleting Substances)
The company does not use ODS such as CCl4 (Carbon Tetrachloride) and HCFC in its production process.
