Kester 24-6337-9721 SN63PB37 58 Core 285 Flux Solder Wire .062 Dia

Kester 24-6337-9721 is a 1 lb spool of leaded, RMA, flux-cored solder wire that has a diameter of .062 inches. It is comprised of SN63PB37, or 63 percent tin and 37 percent lead. Additionally, it has a 58 core size and a 285 (RMA) flux type.Kester 285 (for lead-bearing and lead-free alloys) mildly activated rosin flux is classified as Type ROL0 flux under IPC J-STD-004. This flux was formerly classified as Type RMA per QQ-S-571. Kester 285 consists of high quality, purified rosin to which a synergistic combination of activating agents has been incorporated. The fluxing ability of 285 is much greater than ordinary mildly activated rosin fluxes. Kester 285 has been developed for use in the electronic industry where difficult assemblies are to be soldered, but process requirements stipulate use of a mildly activated rosin flux.
