Wow, this has been real interesting reading. Kind of like a Jerry Springer Forum. "Today on SMTA Forum, cranky engineers and over zealous sales people square off to decide if the replies to the thread are appropriate" When some one asks a questions

First, don�t get distracted by �OA� and �NC� formulations. This is nomenclature. We want to discuss the issue of �activity�. J-STD-004 "Requirements for Soldering Fluxes" classifies fluxes by their chemical composition, activity level and halide c
