9-2 Soldering Condition
Reflow soldering should be done at 240°C
within 20 seconds. Flow soldering should be
done at 260°C within 10 seconds. Please
use suitable solder quantity, too much
solder may affect performance of product.
10. Recommended Washing Condition
Propil alcohol and methyl alcohol used for the washing process will not affect the part performance.
Ultrasonic cleaning should be changed to condition for size of printed wiring board and
type of oscillator. Overpowering of ultrasonic cleaning will cause problems according to resonant
phenomenon. Condition of ultrasonic cleaner should be confirmed prior to use.
We recommend the following conditions.
Ultrasonic power: Within 20W/1
Cleaning times: Within 5 minutes
11. Storage
Chip inductors should not be stored under high temperature and high humidity conditions.
In particular, do not store
taping
where it is exposed to heat or direct sunlight. Otherwise,
the packing material may be deformed, causing problems during mounting.
