Kester 24-7068-1406 is a 1 lb spool of lead-free, RA, flux-cored solder wire with a diameter of .025 inches. It is comprised of SN96.5AG3CU.5, or 96.5 percent tin, 3 percent silver, and .5 percent copper. Additionally, it has a core size of #66 and a 48 (RA) flux type.
Product Description:
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 458 builds on the performance of its predecessor Kester 44 with "instant-action" wetting to provide fast and reliable solder joints
Performance Characteristics:
Unparalled wetting performance
Excellent solderability and fast wetting to a variety of surface finished
Eliminates the need and expense of cleaning
Low smoke and odor
Low spattering
Classified as ROM1 per J-STD-004
Kester 48 vs Kester 44:
Kester 28 provides a higher level of activity than Kester 44, see Spread Test opposite.
Kester 48 dramatically reduces splattering by 50% over Kester 44
Kester 48 residues are transparent and nearly colorless compared to the traditional amber appearance of Kester 44
Kester 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).
