Kester 979VT is a specialized soldering flux designed for high-quality, low-defect soldering of lead-free electronic circuit board assemblies. Here are its key features and benefits:

  1. VOC-Free: Being VOC-free, it aligns with environmental regulations and reduces the emission of volatile organic compounds, ensuring a safer working environment.
  2. No-Clean Formulation: The no-clean formulation eliminates the need for additional cleaning steps after soldering, saving time and resources while still maintaining high-quality solder joints.
  3. Fine-Tuned Activation System: The flux’s activation system is finely tuned to provide excellent wetting, resulting in shiny solder joints, which is crucial for ensuring reliable electrical connections.
  4. Reduces Micro-Solderballing: It effectively reduces micro-solderballing on glossy and matte laminates as well as between connector pins, improving soldering efficiency and reducing defects.
  5. Compatibility: Kester 979VT is formulated to be compatible with various materials commonly used in electronic assemblies, including properly cured solder masks and FR-4 Epoxy-Glass laminate.
  6. Single-Sided Board Assemblers: Specially formulated to accommodate the needs of single-sided board assemblers, ensuring optimal performance and ease of use in their processes.
  7. No Visible Residue: Unlike earlier no-clean flux formulas, Kester 979VT leaves no haze or visible residue behind, including the white powdery residue associated with some other fluxes.
  8. Classification: It is classified as ORL0 under IPC JSTD-004 and ORM0 under IPC JSTD-004B, indicating its high reliability and low risk of corrosion or other detrimental effects on electronic components.

Overall, 979VT Soldering Flux offers a reliable, high-performance solution for soldering lead-free electronic circuit board assemblies, meeting industry standards for quality and reliability while also providing environmental benefits through its VOC-free formulation.
