Occasionally, IC analyses are reported to have elevated levels of acetates and formates.   Is it the general consensus that source of these contamination is assumed to be the decomposition of larger molecular weight weak organic acids found in soldering fluxes?  I can't imagine that any manufacturer would actually be placing acetic or formic acids directly into a flux formulation. These are much too volatile and aggressive. 

Thoughts?
