High reliability wave soldering flux with ultra low flux residue


Low-residue flux with one-step-ahead reliability

Hydrophobic residue prevents migration

The residue of JS-E-3102 is made hydrophobic by adding a small amount of special rosin, which prevents the occurrence of leakage current. Ensures high electrical reliability even in highly humid environments.

Fast drying at room temperature; ideal for selective soldering

Fast drying speed of the residue at room temperature enables soldering by local flowing where pre-heating is not conducted. After soldering the insulation resistance of the residue swiftly recovers, delivering high electrical reliability.

Ultra-low residue after soldering

Reduction of residue was pursued for JS-E-3102, resulting in incredibly low solid content of 2.7% for highly reliable post flux series suitable for automotive applications.
