Kester "245" Low Residue Flux for cored solder wire was developed to complement the newer generations of Low Residue liquid fluxes being used by the electronics industry. The chemistry is based on some of the same principles that have been safely used for years in mildly acctivated rosin fluxes. The use of "245" Low Residue Flux results in the visably acceptable assemblies without cleaning, yet soldering quality and efficiency is comparable to that obtained with mildly activated rosin flux. Kester "245" Low Residue Flux is classified as Type ROL0 flux under IPC ANSI/J-STD-004 Joint Industry Standard. This flux is formerly classified as Type LR per MIL-F-14256.
