Kester 24-9574-1406 K100LD 66 Core 48 Flux Solder Wire .025 Dia

Kester 24-9574-1406 is a 1 lb spool, of lead-free, Ultrapure K100LD, RA flux-cored solder wire with a diameter of .025 inches. It has a 66 core size and a 48 (RA) flux type.
Ultrapure K100 LD (is a lead free solder alloy):Compares favorably to other low-cost, lead-free alloys of tin and copper in terms of wetting and flow characteristics.Low cost, lead-free alloyBright, smooth solder joints with no visible shrinkage effectsExcellent through-hole penetration and topside filletLow dissolution of copper from boards and components into solder potEutectic alloy20% Lower dross rate than SN63Pb37 in laboratory testsLess corrosive to solder pots than SAC305
48 Activated Rosin Cored Wire (lead-bearing amp; lead-free alloys):Kester 48 Activated Rosin Flux for cored solder wire was developed for lead-free applications to enable soldering of most common metals. Kester 48 has performance characteristics far exceeding standard RA fluxes. Kester 48 builds on the performance of its predecessor Kester 44 with "instant-action" wetting to provide fast and reliable solder joints.
Performance Characteristics of 48 Activated Rosin:Unparalleled wetting performanceExcellent solderability and fast wetting to a variety of surface finishesEliminates the need and expense of cleaningLow smoke and odorLow spatteringClassified as ROM1 per J-STD-004
Kester 48 vs Kester 44:Kester 48 provides a higher level of activity than Kester 44Kester 48 dramatically reduces splattering by 50 % over Kester 44Kester 48 resides are transparent and nearly colorless compared to the traditional amber appearance of Kester 44Kester 48 was designed for lead-free alloys
RoHS Compliance:This product meets the requirements of the RoHS (Restriction of Hazardous Substances) Directive, 2002/95/EC Article 4 for the stated banned substances. (Applies only if this core flux is combined with a lead free alloy)
