979VT Soldering Flux, Contains Halogen, No-Clean, VOC-Free, 1 Gallon
Kester 979VT is a VOC-free, no-clean flux formulation for high-quality, low-defect soldering of lead-free electronic circuit board assemblies. This flux's finely tuned activation system offers the best wetting available in VOC-free liquid flux technology and the shiniest solder joints. 979VT also reduces micro-solder balling on glossy and matte laminates and between connector pins. 979VT will not attack properly cured solder masks or FR-4 Epoxy-Glass laminate. It has been specially formulated to accommodate the needs of single-sided board assemblers. 979VT leaves no haze or visible residue behind, including the white powdery residue associated with the use of earlier no-clean formulas. 979VT is classified as ORL0 under IPC JSTD-004 and ORM0 under IPC JSTD-004B.
