August 21, 2026 Kester 979 Soldering Flux for Electronic Assembly
Kester 979 Soldering Flux is a VOC-free, no-clean flux formulation designed for high-quality, low-defect soldering of electronic circuit board assemblies. Manufactured by Kester, this liquid flux delivers exceptional performance while meeting environmental compliance standards for modern electronics manufacturing.
Advanced Performance Features
The finely tuned activation system in Kester 979 offers the best wetting available in VOC-free liquid flux technology, yielding the shiniest solder joints. Additionally, this formulation reduces micro solderballing on glossy laminates and between connector pins, ensuring robust electrical reliability.
Material Compatibility and Residue Properties
Kester 979 Soldering Flux will not attack properly cured solder masks or FR-4 Epoxy-Glass laminate. Following the soldering process, Kester 979 Soldering Flux leaves a minimal amount of residue. All remaining residues are completely non-corrosive, non-conductive, and do not need to be removed from the board assembly.
