- High Activity
- Minimizes Icicling and Bridging
- Chemically Compatible with most Solder Masks and Board Laminates
- High Ionic Cleanliness and No Surface Insulation Resistance Degradation
- Excellent Choice for Surface Mount Boards
- RoHS Compliant
Kester 2235 is a high activity, organic flux designed for automated soldering of circuit board assemblies where a more aggressive flux is required, but reliability considerations are paramount. Featuring low solids, 2235 flux is ideal for soldering circuit assemblies with surface mounted components. Low solids mean fewer skips on bottom side surface mount pads. The residue after soldering is effectively removed in standard water cleaning systems. Although possessing high activity, boards exhibit high ionic cleanliness after water cleaning, exceeding the requirements of MIL-P-28809. The minimal amount of flux residue after soldering results in longer life for deionizing resin beds in closed loop water recycle systems. No offensive odors or excessive smoke is emitted during soldering. The flux will not create excessive foaming in standard water cleaning systems.
