In 1999, 440-R SMT Detergent was certified for specific parameters of environmental safety, user safety and cleaning efficiency by the California Environmental Protection Agency (Cal/EPA) as the chemistry used in an ultrasonic stencil cleaner. Subsequent to the Certification by Cal/EPA, the data was Verified by the U.S. Environmental Protection Agency (EPA).|
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 letter from the Cal/EPA DTSC below). Recertification of the California EPA data would be important and necessary only if the overall process has changed or a different chemistry was used.
440-R SMT Detergent is the only stencil cleaning chemistry to meet the "Test of Time" and has not changed since its introduction in 1990. 440-R SMT Detergent has been able to clean any type of solder paste that has been introduced from any fine-pitch stencil. Whenever a 440-R SMT Detergent customer has found a need to change flux types or solder paste brands, 440-R SMT Detergent was able to support the change. Assemblers using other chemistries often find themselves needing to change chemistries and/or equipment when they change solder pastes affecting not only the capital budget, but also impacting waste treatment and environmental concerns.
Today, 440-R SMT Detergent remains the only stencil cleaning chemistry ever to pass California EPA Certification and complete the US EPA's Environmental Technology Verification (ETV) Program. No other stencil cleaning chemistry has been able to meet these stringent guidelines.

ENVIRONMENTAL TECHNOLOGY VERIFICATION STATEMENT
The U.S. Environmental Protection Agency has created a program to facilitate the deployment of innovative environmental technologies through performance verification and information dissemination. The goal of the Environmental Technology Verification (ETV) Program is to enhance environmental protection by substantially accelerating the acceptance and use of innovative, improved, and more cost-effective technologies. The ETV Program is intended to assist and inform those individuals in need of credible data for the design, distribution, permitting, and purchase of environmental technologies. This verification statement provides a summary of performance results for the Smart Sonic Aqueous Cleaning Systems, registered trademark SMARTSONIC®.
The EPA's ETV Program, in partnership with recognized testing organizations, objectively and systematically documents the performance of commercial ready environmental technologies. Together, with the full participation of the technology developer, they develop plans, conduct tests, collect and analyze data, and report findings. Verifications are conducted according to a rigorous workplan and established protocols for quality assurance. Where existing data are used, the data must have been collected by independent sources using similar quality assurance protocols. EPA's ETV Program, through the National Risk Management Research Laboratory (NRMRL), has partnered with the California Department of Toxic Substances Control (DTSC) under an ETV Pilot Project to verify pollution prevention, recycling, and waste treatment tecnonlogies.
Smart Sonic Corporation developed the Model 2000 and Model 4200 ultrasonic aqueous cleaning systems to replace 1, 1, 2-trichloro-1, 2,2-trifluoroethane (CFC-113), 1,1,1-trichloroethane (1,1,1-TCA) and isopropyl alcohol (IPA) based systems used in the electronics industry to clean various types of solder pastes from printed circuit board stencils.
Smart Sonic's stencil cleaning technology consists of Smart Sonic's proprietary 440-R SMT Detergent®, ultrasonic generator and 40 kHz piezoelectric transducers, stainless steel wash tank, rinse tank (included in semi-automated system), and control devices.
The semi-automated Model 2000 system is approximately 3 feet high with a 40 x 44 inch base. This unit has a separate wash tank and a manual rinse station. The automated Model 4200 system is approximately 50 inches high with a 36 x 62 inch base. The pneumatic lift used on this model extends 36 inches for a total system height of 86 inches. This system has one tank for washing with an automated rinse over the wash tank.
Between May and September 1998, an evaluation of two ultrasonic aqueous cleaning systems, developed by the Smart Sonic Corporation, was conducted using field and laboratory qualitative and quantitative data. The aqueous cleaning systems include Smart Sonic's Model 2000 and Model 4200 systems. The objectives of this evaluation were to verify, through independent sources, the following performance parameters:
VERIFICATION OF PERFORMANCE
Performance results of Smart Sonic Corporation's aqueous cleaning systems, Model 2000 and Model 4200, are as follows:
End-users should contact their stencil manufacturer prior to changing their cleaning process. Changing from solvents to aqueous cleaning systems may require stencil modifications to make the cleaning system and stencil compatible. In addition, the end-user should contact his/her local, state, or federal regulatory authority regarding management of spend hazardous wastes generated from use of the Smart Sonic aqueous cleaning systems (i.e., spent cleaning baths, rinse baths, and solids containing lead).

Dear Mr. Schreiber:
Your submitted product(s) have successfully met all of the requirements for a Clean Air Solvent Certificate from the South Coast Air Management District (AQMD). The certification will be valid for five (5) years from the date of issuance and may be renewed upon recertification by the AQMD. The following product(s) will be classified as CAS(s) by the AQMD:
A CAS certificate will be issued for each qualifying product in the near future. Congratulations and our sincere thanks for your help in cleaning up the air! If you have any questions, please contact Mr. Louis Yuhas (909) 396-2475.

Stationary Source Compliance
Smart Sonic's 440-R SMT Detergent is certified as a "Clean Air Solvent" by the South Coast Air Quality Management District CAS Program.|
CAUTION: The Clean Air Solvent (CAS) Program only certifies the chemistry. If a CAS chemistry is used in a hazardous stencil cleaning application (lead) the resulting waste stream is not CAS certified. Only the Environmental Technology Verification (ETV) Program of the EPA tests and verifies complete processes.

REPORT OF LABORATORY ANALYSIS
Clean Air Solvent (CAS) eligibility determination by SCAQMD Method 313-91.
Conclusion: The product meets CAS criteria.
The Smart Sonic SMT Screen/Stencil Cleaning Process is the only truly environmentally safe cleaning process. California's Air Quality Management District has certified Smart Sonics's 440-R SMT Detergent as a "Clean Air Solvent" (1997).|
Most people will agree that California is the most environmentally regulated area in the world. The regulating agency in Northern California (Silicon Valley) is the Bay Area Air Quality Management District (BAAQMD). The BAAQMD has exempted the Smart Sonic Cleaning Process from all permit requirements because of it's environmental compatibility!
The following is a letter from the BAAQMD to a Smart Sonic customer in the Silicon Valley area:
December 24, 1991
Dear Mr. Marsh:
We have determined the following equipment to be currently exempt from District permit requirements per Regulation 2-1-118.5:
Screen/Stencil Cleaning System, Smart Sonic.
Note that the exemption is not permanent, and apply only to permit requirements. A change in your operations, such as usuing materials other than Smart Sonic 440-R Solderpaste Remover, or a revision of District Regulations, may require you to obtain permits in the future. You must continue to comply with all other applicable District regulations.
Please keep a copy of this letter on-site as a record of the exemption status of the above equipment.
