The Environmental Cost of Green
SMTnet - Electronic Industry Hub

Aqueous Technologies UniversityThe Environmental Cost of Green

Being involved in the electronics assembly industry for more than 23 years, specifically in the field of defluxing and cleanliness testing, I have seen my share of environmental regulations. Long before the debate over lead-free alloys, there was the Montreal Protocol.

Back in the late 1980s and early 1990s, the elimination of CFC-based defluxing solvents dominated the covers of industry trade magazines. Emissions from Freon and Trichlorethene-based defluxing solvents threatened the Earth's ozone layer and would soon become banned from use.
