5ml Soldering Flux

2.99

Kester 979 VOC-free, No-Clean, soldering flux conveniently packaged in a syringe for easy, targeted DIY dispensing. Best results are obtained when solder cups, tabs, wire, boards are pre heated with a heat gun or hot hair dryer after flux is applied to evaporate the thinner (DI water) used in 979. This reduces splattering and improves soldering performance.

Includes:

  • 5ml of Kester 979 VOC-free, No-Clean soldering flux.

  • 1x 6ml manual syringe.

  • 27 gauge, 1/2 inch long tip.

  • syringe cap/upright stand.

  • Kester 979 flux is formulation for high quality, low-defect soldering of connectors and 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. 979 also reduces micro solderballing on glossy laminates and between connector pins. 979 leaves a minimal amount of residue after soldering and all remaining residues are non-corrosive, non-conductive and do not need to be removed. 979 will not attack properly cured solder masks or fiber reinforced laminate.
