1-1. Preheating when soldering
1. Since flux may have a significant effect on the performance of inductors, it is necessary to verify the following conditions prior to use;
1. Temperature, time, amount of solder, etc. are specified in accordance with the following recommended conditions, and please contact us about peak tem-
(2) When soldering inductors on the board, the amount of flux applied should be controlled at the optimum level.
(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

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.
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.

2. Because excessive dwell times can detrimentally affect solderability, soldering duration should be kept as close to recommended times as possible.
2. The temperature difference between the inductor and melted solder should not be greater than 100 to 130℃.
3. Cooling after soldering should be as gradual as possible.
4. Wave soldering must not be applied to the inductors designated as for reflow soldering only.
2. The soldering iron should not directly touch the inductor.
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 below:
1. Make sure the inductors are preheated sufficiently.
1. Use a 20W soldering iron with a maximum tip diameter of 1.0 mm.
