Kester 331 Flux-Cored Wire Overview
The Kester 24-6337-6401 solder wire is part of the 331 series, featuring a Sn63Pb37 alloy with a 3.3% flux core. This water-soluble formula is designed for use in flux-cored solder wire, offering excellent solderability to a wide variety of metalizations. The 331 Organic Flux is a mild, non-corrosive formula that is more effective than rosin fluxes in soldering difficult metals.
Performance Characteristics
The Kester 331 flux-core wire offers a range of performance characteristics that make it an ideal choice for soldering applications. These include excellent solderability, easy removal in hot water, and compatibility with both leaded and lead-free alloys. The flux is classified as ORH1 per J-STD-004B, ensuring reliable performance in demanding applications.
Advantages of Kester 331 Organic Flux
The 331 Organic Flux offers several advantages over other flux formulas. It is heat-stable, resulting in minimal smoke and odor during soldering. The flux residue can be completely removed with a simple heated water rinse, making it easy to clean up after soldering. Additionally, the flux is classified as ORH1 per J-STD-004B, ensuring reliable performance in demanding applications.
Importance of Residue Removal
It is important to note that the 331 flux residue is conductive and can cause corrosion of metal parts over time. Therefore, residue removal should be completed within 48 hours of soldering. Using softened tap water or deionized water is recommended for high reliability, as hard or high mineral content tap water can increase ionic cleanliness measurements.
