Product Overview
Kester 985M is broad spectrum, halide free liquid flux, developed for use in both traditional tin-lead and lead-free solder alloys.
The unique activation package of Kester 985M makes it a wide process window flux suitable on both standard and high density assemblies.
This flux exhibits excellent wetting properties to minimize solder bridges and solder balls during all soldering operations. The residues are minimal and not apparent, excellent for pin testing.
Product Features
- Halide-free
- Broad spectrum liquid flux for general wave soldering application
- Excellent soldering performance with good hole-fill and low bridging on high density assemblies
- High reliability meeting the toughest ECM/SIR IPC 004B requirements
- Evenly, tack free and pin testable residues
- ORM0 per IPC J-STD-004B
Low Solid, Broad Spectrum, High Activity Flux
Kester 985M flux is a low-solids, no-clean flux, specially designed to improve effectiveness in the wave soldering of conventional circuit board assemblies.
Kester 985M is excellent for solderability to a variety of board finishes.
It provides excellent soldering on difficult lead-free wave soldering applications, even after double-sided reflow.
The minimal remaining residue is non-tacky so that boards are cosmetically clean as they exit the wave solder machine.
