Replacing chlorofluorocarbons (CFCs) in the metal cleaning process
The Montreal protocal requiring industries to phase out the production and use of ozone depleting compounds(ODC), i.e. Freon TE, has prompted Lawrence Livermore National Lab (LLNL) to identify high performance environmentally benign cleaners that could replace Freon TE. My project; with the mentor ship of Ralph Hershey, Mike Meltzer, and Dave Miscovich; is to identify high performance alternative solvents that could replace Freon TE, which is a CFC-113, in metal cleaning and plastic processes, specifically printed board assemblies(PBA). All the alternative solvents we chose for our project can adequately remove flux and contaminants from PBAs via ultrasonic cleaning. Also, we wanted to know the efficiency of these cleaners on the PBAs compared to Freon TE if aged a simulated 15-20 years. This paper will briefly discuss the Alternative Testing Program at LLNL followed by a description of the methods used in my project. However, any conclusive results cannot be made until more extensive research is done.
