August 19, 2026 Kester 920-CXF Flux for Wave Soldering
The Kester 920-CXF Flux is a premium zero-halogen, low solids, no-clean organic liquid flux designed specifically for wave soldering conventional and surface mount circuit board assemblies. Developed by Kester, this high-performance formulation eliminates common defects often experienced in surface mount assembly wave soldering operations when using traditional fluxes.
Key Benefits of Kester 920-CXF Flux
Engineered for high-reliability electronics manufacturing, this non-corrosive and non-conductive flux offers exceptional process advantages:
- Zero-Halogen & Low Solids: Features an extremely low solids content, leaving virtually no residue on the printed circuit board assembly after soldering.
- Eliminates Cleaning Costs: Because there are no harmful residues left to interfere with electrical testing, secondary cleaning operations and associated expenses are completely eliminated.
- Dry PCB Output: Printed circuit board assemblies emerge completely dry as they exit the wave solder machine.
- Superior Insulation Resistance: Provides a surface insulation resistance significantly higher than typical organic water-soluble fluxes, ensuring total electrical reliability.
Substrate Compatibility and Applications
This formulation is highly versatile and suitable for wave soldering both bare copper and solder-plated circuit boards. To achieve optimum soldering performance with Kester 920-CXF Flux, it is recommended that bare copper boards remain free from excessive oxides and organic contamination prior to processing.
