Performance Attributes and Key Advantages
Formulated for demanding production environments, Kester 2222-CL Flux combines high reactivity with easy aqueous post-solder cleanup. Core performance features include:
- High Organic Acid Activity: Designed with an aggressive activation system capable of wetting difficult metal surfaces and heavily oxidized leads.
- Maximum Hole-Fill Performance: Promotes superior capillary wetting action up plated through-holes, making it ideal for thick multilayer printed circuit boards.
- Polyglycol-Free Chemistry: Formulated without polyglycols, which can compromise long-term board surface insulation resistance (SIR).
- Aqueous Cleanability: Produces bright, shiny solder joints with residues that wash away completely in standard water cleaning equipment.
- Dip Tinning Versatility: Highly suitable for select dip tinning operations that demand a robust, high-activity fluxing media.
Assembly Reliability
By excluding polyglycol compounds, Kester 2222-CL Flux ensures high surface insulation resistance following water wash cycles, protecting sensitive circuitry against electromigration and leakage current.
