Kester 979 is a completely new, organic, no-clean flux formulation for high quality,
soldering of electronic circuit board assemblies. Its chemistry is free of any volatile
compounds (VOCs), solvents that may react photochemically to form
air pollution (smog).
This flux's finely tuned activation system offers the
best wetting available in VOC-Free liquid
flux technology and the shiniest
solder joints. Kester 979 offers excellent soldering properties
to higher productivity without sacrificing reliability of the assembly. Kester 979
reduces microsolderballing on glossy laminates and between connector
Classified as ORL0 per ANSI-J-STD-004, Kester 979 will not attack properly
masks or FR-4 Epoxy-Glass laminate. After its use, the cosmetic
appearance of the board's
surface is excellent. For example, Kester 979 leaves
no haze or visible residue behind,
including the white powdery residue associated
with use of earlier no-clean formulas.
The miniscule amount of non-visible residue that remains after soldering is non-conductive,
and does not have to be removed. In addition, the residues will
not interfere with incircuit
testing probes. Kester 979 is not detrimental
to the Surface Insulation Resistance (SIR)
of the soldered assembly. If the
user still chooses to clean the circuit board assembly because of process considerations,
the minute amount of non-visible residue can be washed easily with plain, warm water
