Special usage

Transparent residual flux
Color tone of flux

The various rosin used for the flux has different colors from transparent to brown one. Also, some active agents and additives are colored due to heat during soldering.

LED lighting board

In LED lighting equipment, white resist is applied to the entire board, and brown flux residue impaires the appearance of the product.

Affect on appearance inspection

On the Board displayed by silk, brown flux residue the visibility deteriorates due to the residue flowing to the display area, especially the visual inspection load to increase.

Selection of solder materials

We have solder materials which weakened the color of flux residues to light color by using light color rosin and less coloring activator, so please contact us.
