979VT
979VT is a formulation for high quality, low-defect soldering of lead-free electronic circuit board assemblies. 979VT reduces micro-solderballing on glossy and matt laminates and between connector pins. It will not attack properly cured solder masks or FR-4 Epoxy-Glass laminate. 979VT leaves no haze or visible residue behind.
979T
Kester 979T is a 100% VOC-free, no-clean flux formulation for high quality, low-defect soldering of electronic circuit board assemblies. 979T is specially formulated with a unique proprietary blend of organic activator system which offers the best wetting and topside hole fill and shiniest solder joints, even with OSP coated copper boards which have undergone at least two thermal excursions. Kester 979T flux also reduces micro-solderballing on glossy and matt
laminates and between connector pins.
Kester 979T leaves a minimal amount of residue after soldering. These residues are non-conductive, non-corrosive and do not need to be removed.
