Key Features of Kester 959 Flux
Engineered for high-yield printed circuit board manufacturing, this solvent-based flux delivers distinct technical advantages:
- Rosin-Enhanced Stability: Formulated with a small percentage of rosin (1%) to boost overall solderability, heat stability, and surface insulation resistance.
- Micro-Solderball Reduction: Specifically developed to restrict micro-solderballing during wave soldering, reducing post-solder rework.
- Superior Joint Aesthetics: Delivers the best wetting and the shiniest solder joints among no-clean, solvent-based chemistries.
- Even Residue Distribution: Leaves uniformly spread, non-corrosive residues for a clean, professional board appearance.
Optimized for High-Reliability PCB Assembly
By integrating Kester 959 Flux into wave soldering equipment, electronics manufacturers achieve consistent wetting across complex surface mount and through-hole joints. The low rosin content provides excellent thermal endurance without sacrificing electrical insulation properties.
