1-1. Preheating when soldering
When using adhesives to mount inductors on a PCB, inappropriate amounts of
adhesive on the board may adversely affect component placement. Too little
adhesive may cause the inductors to fall off the board during the solder process.
Too much adhesive may cause defective soldering due excessive flow of adhe-
sive on to the land or solder pad.
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.
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.
applied, a large amount of flux gas may be emitted and may detrimentally
affect solderability. To minimize the amount of flux applied, it is recom-
mended to use a flux-bubbling system.
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.
must be conducted with a great care so as to prevent malfunction of the
components due to excessive thermal shock.
