Elimination of Ozone Depleting Chemicals at M/A-COM, Inc. 1993.

TURI Technical Report No. 9. Traditionally, cleaning steps in fabrication and assembly have often relied upon chlorinated solvents and chloroflurocarbon solvents for the removal of flux residues. With the identification of chloroflurocarbon 113 (a.k.a. Freons) as a contributor to the ozone depletion in the stratosphere, there is an expedience to reevaluate cleaning and to find ODC free alternatives that at a minimum are at least technically equal to existing methodologies. Industry has been looking at all cleaning media to evaluate their health potential to operators who use them, to the air we breath, to the water we drink and to the stratospheric ozone which protects us from harmful ultraviolet radiation. Solvent cleaning and aqueous/semi-aqueous cleaning must meet stringent guidelines when introduced in a manufacturing environment. New cleaning materials have been developed in an attempt to meet the needs of the industry and to provide safe alternatives.
