• 922-CX Soldering Flux
• Size: 1 Gallon
• Halogen Content: Zero-Halogen
• Type: No-Clean

Kester 922-CX is a non-rosin organic flux designed for wave soldering conventional and surface-mount circuit board assemblies. This flux eliminates defects often experienced in surface mount assembly wave soldering operations with traditional fluxes. This non-corrosive and non-conductive flux has an extremely low solid content. There is essentially no residue left on the assembly after soldering. There are no residues to interfere with electrical testing and the expense of cleaning is eliminated. A particular feature of 922-CX is the very dry appearance of PCB assemblies as they exit the wave solder machine. Although cleaning is eliminated, the flux will not harm the electrical reliability of the assembly.

This product meets the requirements of the RoHS (Restriction of Hazardous Substances) Directive, 2002/95/EC Article 4 for the stated banned substances.

922-CX can be applied to the assembly by dipping, spraying, or wave fluxing. The usable preheat temperature range is 82 to 110 °C (180 to 230 °F), but the optimum preheat temperature for most PCB assemblies is 99 to 110 °C (210 to 230 °F), as measured on the circuit board's top or component side. Insufficient preheat tends to leave more residue behind after soldering. Excessive preheating time or temperature can partially degrade the flux and result in icicles or solder shorts.
