Kester 985M Soldering Flux for Circuit Assemblies
Kester 985M Soldering Flux is a low-solids, halide-free, no-clean liquid flux engineered for wave soldering, selective soldering, and touch-up operations. Developed by Kester, this formulation is versatile enough for use with both traditional tin-lead and lead-free solder alloys.
Bridging Reduction and Process Versatility
Designed to optimize assembly yield, Kester 985M exhibits improved soldering performance that actively minimizes solder bridges (shorts) across all soldering operations. Whether applied in automated wave soldering machines or manual touch-up steps, 985M Soldering Flux ensures clean, defect-free solder joints.
High-Reliability Industry Applications
Because of its non-corrosive and halide-free chemistry, Kester 985M Soldering Flux is ideal for demanding sectors where long-term operational reliability is critical, including automotive, computing, and telecommunications electronics assembly.
