Kester 24-6040-9703 SN60PB40 66 Core 285 Flux Solder Wire .015 Dia

Kester Solder 24-6040-9703 is a 1 lb spool of leaded solder wire that has a diameter of .015 inches. It is comprised of SN60PB40, or 60 percent tin and 40 percent lead. Additionally, is has a 66 core size and a 285 (mildly activated rosin) flux type. Kester 285 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 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.
