Kester 24-6040-9718 SN60PB40 66 Core 285 Flux Solder Wire .025 Dia

Kester 24-6040-9718 is a 1 lb spool of leaded, RMA flux-core solder wire with a .025 inch diameter. It is comprised of SN60PB40, or 60 percent tin and 40 percent lead. Additionally, is has a 66 core size and a 285 (RMA) flux type. RMA cored wire is for lead-bearing and lead-free alloys. Kester 285 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 and is comparable to fully 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.
