Alternative cleaning methods and materials were required to reduce the use of ozone-depleting solvents or potentially hazardous materials (chlorofluorocarbons and chlorinated hydrocarbons) at purchased product suppliers. Three groups of printed wiring boards were fabricated by Sparton Technology Inc., the vendor selected to complete the project. These printed wiring boards were evaluated in the Materials Engineering laboratory at the Kansas City Division. Recommendations included using a rosin-based flux and an enhanced cleaning process with Bioact EC-7R as the preferred solvent. Results of the study were included in the Solvent Waste Stream database
