August 19, 2026 Kester 951 Flux for Wave Soldering
The Kester 951 Flux is an industry-leading zero-halogen, non-rosin organic flux engineered for wave soldering conventional and surface mount circuit board assemblies. Formulated by Kester, this liquid flux features an extremely low solids content of 2.0% paired with an advanced activator system to deliver clean, highly reliable electronic assemblies.
Key Performance Benefits
Designed to optimize high-volume wave soldering operations, this non-rosin formulation offers distinct process and reliability advantages:
- Zero-Halogen & Low Solids (2.0%): Leaves practically no residue on the circuit board assembly after soldering, eliminating post-solder cleaning costs.
- Minimizes Defects: Exhibits improved soldering performance to significantly reduce solder bridges (shorts) and excessive solder defects during wave soldering.
- Dry and Cosmetically Clean Output: Circuit boards exit the wave solder machine completely dry and cosmetically clean, with no residues left to interfere with electrical testing.
- Corrosion Inhibitor Protection: Contains a specialized corrosion inhibitor so that no corrosion products are formed when bare copper surfaces are exposed to humid environments.
- Superior Surface Insulation Resistance: Provides a surface insulation resistance on soldered boards higher than that provided by typical water-soluble fluxes.
Industry Applications
Because reliability considerations are critical in modern electronics manufacturing, Kester 951 Flux is ideally suited for demanding sectors such as automotive electronics, computing hardware, telecommunications, and high-density SMT assemblies.
