Kester 988 Soldering Flux for Lead-Free Wave Soldering
Kester 988 Soldering Flux is a low-solids, no-clean liquid flux specially designed for excellent solderability and best-in-class through-hole fill in lead-free wave soldering processes. Developed by Kester, this formulation offers exceptional performance for complex printed circuit board assemblies.
Superior Through-Hole Fill and Solderability
Engineered for demanding lead-free thermal profiles, Kester 988 promotes outstanding wetting characteristics that drive deep hole penetration. By ensuring complete vertical barrel fill, Kester 988 Soldering Flux prevents joint defects and enhances mechanical strength across double-sided and multilayer circuit boards.
Cosmetic Board Finish and Non-Conductive Residues
The post-soldering residue left by Kester 988 Soldering Flux is evenly distributed and non-tacky, keeping circuit boards cosmetically clean upon exiting the wave soldering equipment. Furthermore, the remaining residue is entirely non-conductive, allowing it to stay on the board without compromising assembly reliability.
