Environmental Safe, User Safe, and Efficiency
In 1999, the Smart Sonic Stencil Cleaning Process was certified for specific parameters of Environmental Safety, user safety and cleaning efficiency by the California Environmental Protection Agency (Cal/EPA). A Smart Sonic automatic stencil cleaner and a Smart Sonic semi-automatic stencil cleaner were evaluated using Smart Sonic’s non-hazardous 440-R SMT Detergent. Subsequent to the Certification by Cal/EPA, the data was Verified by the U.S. Environmental Protection Agency’s Environmental Technology Verification (ETV) Program.
While the California EPA Certification data is valid for a period of three years, the U.S. EPA Verification of that data is permanent and does not expire (See the EPA Complete Report). Recertification of the California EPA data would be important and necessary only if the overall process has changed or a different chemistry was used.
