4. Soldering
Precautions
◆Selection of Flux
1. Since ux may have a signicant effect on the performance of inductors, it is necessary to verify the following conditions prior to use;
（1）Flux used should be with less than or equal to 0.1 wt%（Chlorine conversion method）of halogenated content. Flux having a strong acidity content should
not be applied.
（2）When soldering inductors on the board, the amount of ux applied should be controlled at the optimum level.
（3）When using water-soluble ux, special care should be taken to properly clean the boards.
◆Soldering
1. Temperature, time, amount of solder, etc. are specied in accordance with the following recommended conditions.
◆And please contact us about peak temperature when you use lead-free paste.
Technical
consider-
ations
◆Selection of Flux
1-1. When too much halogenated substance（Chlorine, etc.）content is used to activate the ux, or highly acidic ux is used, an excessive amount of residue
after soldering may lead to corrosion of the terminal electrodes or degradation of insulation resistance on the surface of the Inductor.
1-2. Flux is used to increase solderability in ow soldering, but if too much is applied, a large amount of ux gas may be emitted and may detrimentally affect
solderability. To minimize the amount of ux applied, it is recommended to use a ux-bubbling system.
1-3. Since the residue of water-soluble ux is easily dissolved by water content in the air, the residue on the surface of Inductor in high humidity conditions may
cause a degradation of insulation resistance and therefore affect the reliability of the components. The cleaning methods and the capability of the machines
used should also be considered carefully when selecting water-soluble ux.
◆Soldering
1-1. Preheating when soldering
Heating: Chip inductor components should be preheated to within 100 to 130℃ of the soldering. Cooling: The temperature difference between the
components and cleaning process should not be greater than 100℃.
Chip inductors are susceptible to thermal shock when exposed to rapid or concentrated heating or rapid cooling. Therefore, the soldering process must be
conducted with a great care so as to prevent malfunction of the components due to excessive thermal shock.

Caution
1. The ideal condition is to have solder mass（llet）controlled to 1/2 to 1/3 of the thickness of the inductor, as shown below:
2. Because excessive dwell times can detrimentally affect solderability, soldering duration should be kept as close to recommended times as possible.
