◆Selection of Flux
1-1. When too much halogenated substance(Chlorine, etc.)content is used to activate the flux, or highly acidic flux 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 flow soldering, but if too much is applied, a large amount of flux gas may be emitted and may
detrimentally affect solderability. To minimize the amount of flux applied, it is recommended to use a flux-bubbling system.
1-3. Since the residue of water-soluble flux 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 flux.
◆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(fillet)controlled to 1/2 to 1/3 of the thickness of the inductor, as shown
