Kester 245 No-clean Cored Wire was developed tocomplementlowresidue liquid fluxes being used by the electronicsindustry.Thechemistry is based on some of the same principles thathavebeensafely used for years in mildly activated rosin fluxes. Theuseof245 No-clean Cored Wire results in visuallyacceptableassemblieswithout cleaning, yet soldering quality andefficiencyiscomparable to that obtained with mildly activatedrosinflux.Kester 245 was formerly classified as Type LRperMIL-F-14256.Kester 245 is Bellcore GR-78 compliant.
