Key Features of Kester 958 Flux
This liquid flux provides a comprehensive range of operational advantages for automated assembly lines:
- Virtually Residue-Free: Leaves essentially no residue, allowing boards to exit wave solder machines dry, cosmetically clean, and ready for electrical testing without interference.
- Enhanced OSP & Bare Copper Wetting: Formulated specifically to improve wetting dynamics on OSP-treated bare copper PCBs.
- Conformal Coating Compatibility: Exhibits excellent compatibility with most standard conformal coatings on the market.
- Corrosion Inhibition & Reduced Odor: Features superior corrosion-inhibiting properties while producing a non-tacky finish and significantly reduced soldering odor.
Optimized for Automated PCB Assembly
Integrating Kester 958 Flux into your wave soldering process streamlines post-solder inspection and testing. Because the non-tacky residue does not obstruct test pins or hinder downstream coating processes, it minimizes rework and enhances production throughput.
