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.

• High Activity
• Minimizes Icicling and Bridging
• Chemically Compatible with most Solder Masks and Board Laminates
• pH Neutral Chemistry

Kester 2331-ZX is an innovation in organic acid water-soluble flux chemistry for soldering circuit board assemblies. This unique, neutral pH chemistry flux provides the best ionic cleanliness of any organic water-soluble flux available to the electronics industry. This popular flux has been used for soldering critical assemblies in the computer, telecommunications and other industries. No offensive odors will be emitted during soldering. Kester 2331-ZX will not create excessive foaming in standard water cleaning systems. Kester 2331-ZX has good soldering properties for improved productivity without sacrificing reliability of the assembly. This flux does not attack properly cured solder masks or FR-4 epoxy-glass laminate. Kester 2331-ZX is not detrimental to the surface insulation resistance of the soldered assembly. Use of this flux minimizes cleaning costs while complying with environmental regulations.

Kester 951 is a halogen-free, non-rosin organic flux designed for wave soldering conventional and surface mount circuit board assemblies. The extremely low solids content (2%) and nature of the activator system results in practically no residue left on the assembly after soldering. Boards are dry and cosmetically clean as they exit the wave solder machine. There are no residues to interfere with electrical testing. Kester 951 exhibits improved soldering performance to minimize solder bridges and excessive solder defects. This flux is suitable for automotive, computer, telecommunications and other applications where reliability considerations are critical. The surface insulation resistance on soldered boards is higher than that provided by typical organic water-soluble fluxes. Kester 951 contains a corrosion inhibitor such that no corrosion products are formed when bare copper surfaces are exposed to humid environments.
