440-R® SMT Detergent 440-R SMT Detergent Spray Bottle

440-R® SMT Detergent is the only stencil-cleaning chemistry verified by the U.S. EPA for specific parameters of Environmental Safety, user safety and cleaning efficiency and is the only stencil-cleaning chemistry to "survive the test of time". 440-R SMT Detergent was introduced in 1990 and is the only chemistry able to clean all solder pastes used in SMT assembly.

For use in all aqueous stencil cleaner machines, spray-in-air, ultrasonic and spray-under-immersion.* Smart Sonic's 440-R SMT Detergent eliminates unpleasant odors, solvent vapors and VOCs, shortens cleaning cycles, and cleans at low temperature to conserve energy and protect stencils. Winner of the SMT Vision Award and Global Technology Award for Best Cleaning Chemistry.

440-R SMT Detergent Spray BottleIn North America, 440-R SMT Detergent is available directly from our master distributor, SMT Detergent Corp.Internationally, you can find your local 440-R SMT Detergent distributor by clicking here: SMT Detergent Distributors

440-R SMT Detergent is also available in Ready-to-use Spray Bottles for manual stencil cleaning. Ready-to-use 440-R SMT Detergent is a safe water soluble detergent that improves cleaning efficiency, improves print production and eliminates the noxious odors, VOCs and hazards associated with solvent cleaning.

The Smart Sonic Stencil Cleaning Process is "Guaranteed to clean any type of solder paste from any fine-pitch stencil."


440-R® SMT Detergent Voted the Best in the World
By Global SMT & Packaging and SMT Magazines


Global TrophyBig AwardNo other stencil-cleaning chemistry has received more awards for cleaning and environmental excellence
The Global Technology Award, The SMT Vision Award, The Canadian High Technology Award, Nepcon's Milton S. Kiver Award and nominated for the U.S. Presidential Green Chemistry Challenge Award.

No other stencil-cleaning chemistry has been verified by the U.S. EPA's Environmental Technology Verification (ETV) Program for specific parameters of Environmental Safety, user safety and cleaning efficiency
Other cleaning chemistries may say they "meet" environmental regulations, but Smart Sonic's 440-R SMT Detergent is the only chemistry to meet the rigid standards of the U.S. Environmental Protection Agency's ETV Program. RoHS and REACH approved

No other stencil cleaning chemistry is completely VOC free
Volatile Organic Compound (VOC) regulations continue to mount while lead-free solder pastes have proven to be more tenacious. Some suppliers have found the need to revert back to VOC solvent additives to supplement their cleaning chemistries. The SCAQMD Clean Air Solvent (CAS) Certification requires that chemistries contain no more than 25 grams per liter of VOCs, down from 50 grams per liter just a few years ago. 440-R SMT Detergent has been able to clean all lead-free pastes without the aid of VOC solvents.

No other stencil-cleaning chemistry has met the test of time
Smart Sonic introduced 440-R SMT Detergent in 1990 and has never needed to modify the formulation. Hundreds of other stencil cleaning chemistries have come and gone causing users to change their cleaning process, modify their waste handling and purchase additional equipment.

No other stencil-cleaning chemistry has been able to clean all types of solder paste
440-R SMT Detergent has been able to clean all solder pastes introduced since 1990. When Smart Sonic customers find it necessary to changed solder pastes or flux types, 440-R SMT Detergent has supported the change.

No other stencil-cleaning chemistry has saved its users tens of thousands of dollars since 1990.
Users of other stencil-cleaning chemistries have found it necessary to change chemistries, change cleaning machines and modify their waste management when a new solder paste or flux was introduced. 440-R SMT Detergent users have not needed to purchase additional stencil-cleaning equipment or change chemistries because of new solder paste or flux technologies, saving users thousands of dollars from potential equipment changes and process modifications. RA, RMA, water washable, no-clean, synthetic and lead-free have all cleaned using the same machine and 440-R SMT Detergent.

No other chemistry is as versatile as 440-R SMT Detergent.
The superior cleaning action of 440-R SMT Detergent works well in spray-in-air, ultrasonic and spray-under-immersion machines as well as manual cleaning applications.

No other stencil cleaning chemistry can also clean SMD adhesive and post solder flux residue
Other suppliers need to provide two or more separate chemistries to effectively clean solder paste, SMD adhesives and post solder flux residues causing different waste streams, cleaning processes and the possible need for additional equipment. 440-R SMT Detergent users need to inventory only one chemistry for all of these applications.

No other stencil-cleaning chemistry is as economical as 440-R SMT Detergent
Chemistry cost for a semi-automatic Model 1500 ultrasonic stencil cleaner is approximately $80 per month. With proper filtration, the bath life can be extended up to 6 months bring the monthly cost down to less than $15.00! The cost for fully automatic models is slightly higher.

No other stencil-cleaning chemistry is used by over 1000 assemblers worldwide
Smart Sonic customers have been satisfied with the performance of 440-R SMT Detergent since 1990 and continue to use it for safe and effective cleaning of stencils, screens, misprinted PCBs, pallets, oven radiators and other flux contaminated tooling. Permali recommends 440-R SMT Detergent and Smart Sonic Stencil Cleaners for the safe cleaning of Durostone pallets. (Durostone Tech Info )

No other stencil-cleaning chemistry does all of the above
Yet 440-R SMT Detergent is non-hazardous and user friendly with a mild pleasant odor.

With Smart Sonic, you always have the choice of using the best chemistry, 440-R SMT Detergent, in our proven, certified and guaranteed stencil cleaning process. Or, select another chemistry and design your own process. Either way, Smart Sonic has been used longer, by more SMT assemblers and recommended by more stencil manufacturers than any other stencil cleaning process.

440-R SMT Detergent will last for weeks, or even months, in your Smart Sonic Stencil Cleaner. However, because of the potential for outside contaminants that can create odors and other complications, it is recommended that the wash solution be changed on a monthly basis. If proper filtration is implemented, the chemistry life can be extended up to 6 months.
