Kester 924-FB Flux for Wave Soldering
The Kester 924-FB Flux is an advanced non-rosin, organic liquid flux engineered for wave soldering conventional and surface mount circuit board assemblies. Formulated by Kester, this high-efficiency flux combines a very low solids content with optimized surface tension properties and an effective activator system to deliver clean, highly reliable electronic assemblies.
Key Features and Benefits
Designed to streamline electronics manufacturing and lower operational expenses, this organic flux offers distinct processing advantages:
- Minimal Post-Solder Residue: Leaves practically no residue on the circuit board assembly after soldering, preserving long-term electrical integrity.
- Dry and Cosmetically Clean PCBs: Circuit boards exit the wave solder machine completely dry and cosmetically clean, eliminating the need for post-solder washing.
- Cost-Saving Efficiency: Because there are no sticky or conductive residues to interfere with electrical testing, the added expense and time of cleaning are eliminated.
- Optimized Activator System: Balances surface tension for smooth, defect-free solder joints across surface mount technology (SMT) and through-hole components.
Substrate Compatibility and Usage
This flux is fully suitable for soldering both bare copper and solder-coated circuit boards. While solder-coated boards provide the preferred solderability protection when using Kester 924-FB Flux, bare copper boards can achieve adequate soldering performance provided they are kept free from excessive oxides and organic contamination prior to processing.
