Kester 24-7068-9720 is a 1 lb spool of lead-free, no-clean, flux-cored solder wire with a diameter of .040 inches. It is comprised of SN96.5AG03CU.5, or 96.5 percent tin, 3 percent silver, and .5 percent copper. Additionally, it has a #58 core size and a 285 (RMA) 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 aility 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.
