Kester "331" Lead-Free, Organic Water-Soluble Flux is more effective than rosin flux when working with difficult-to-solder metals. Organic flux is more heat stable than most organic fluxes and the residue can be completely removed with a simple water rinse. Neutralizers, saponifiers or detergents are not necessary for residue removal.
Applications:
• Recommended for SMT and hand soldering assembly applications.
Product Performance
• Excellent solderability for a wide variety of metallization processes
• Easy residue removal with softened tap water or deionized water (recommended)
• Neutralizers, saponifiers or detergents are not necessary for residue removal
• Produces a minimal amount of smoke and odor
• Residue is conductive and may cause corrosion of metal parts over time.
