440R SMT Detergent is now available in ready-to-use spray bottles for safe and effective manual cleaning of SMT stencils and related tooling. 440R SMT Detergent is the most widely used and only stencil-cleaning chemistry verified for specific parameters of environmental safety, user safety and cleaning efficiency by the U.S. EPA's Environmental Technology Verification Program. While ultrasonic technology is the most effective methodology for removing solder paste from SMT stencils, manual cleaning continues to be the most common methodology worldwide.

Stencil cleaning has been identified as the most hazardous process with the greatest potential environmental impact associated with SMT assembly. Flammable and VOC solvents such as alcohol and acetone have been commonly used. Ready-to-use 440R SMT Detergent replaces these hazardous solvents with a safe water soluble detergent that cleans more effectively to improve print production and eliminates the noxious odors and hazards associated with solvent cleaning.

440R SMT Detergent was winner of this year's Global Technology Award for Best Cleaning Material presented at the 2005 Productronica Show in Munich Germany. The Global Technology Award celebrates the very best innovations in the printed circuit assembly and packaging industries.

Stencil cleaning has been identified as the most hazardous process associated with SMT assembly; heavy metal exposure, noxious / flammable chemistries and vapors all pose hazards to the operator. 440R SMT Detergent eliminates these hazards with a mildly alkaline non-hazardous and environmentally safe aqueous detergent.

440R SMT Detergent was formulated specifically to clean all types of solder paste from fine-pitch stencils while eliminating the health, safety and environmental hazards of VOC solvents such as alcohol and terpenes and hot corrosive saponifier chemistries commonly used in stencil-cleaning applications.

440R SMT Detergent is the only cleaning chemistry verified for specific parameters of environmental safety, user safety and cleaning efficiency by the U.S. Environmental Protection Agency's Environmental Technology Verification Program yet, when used in a Smart Sonic Stencil Cleaner, it is guaranteed to clean any type of solder paste from any fine-pitch stencil which is important if the assembler needs to use multiple solder pastes or plans to change solder pastes in the future as 440R SMT Detergent will support the change and not require a change of chemistry, equipment or waste management protocol.

440R SMT Detergent effectively cleans all types of solder paste without heat. Stencils are heat-sensitive and most stencil manufacturers recommend their stencils not be exposed to temperatures higher than 43° C (110° F) as the glue that bonds the screen to the frame and metal-etched foil is heat-cured. Hot wash water or hot drying air can breakdown the glue causing detachment, distortion or misregistration of the etched image due to expansion and contraction. 440R SMT Detergent eliminates these concerns and conserves energy.

Because 440R SMT Detergent contains no hazardous ingredients or VOCs, the wastewater qualifies for routine liquid evaporation in standard evaporation equipment. The non-hazardous liquid can be evaporated to atmosphere reducing everything back to the original solid solder paste for recycling. When using an evaporator, there's absolutely no liquid hazardous waste for disposal.

Most applications require less than 3 gallons (12 litres) per month at a total cost of less than only $140.00! 440R SMT Detergent also cleans post solder flux residues from pallets & oven radiators and safely removes wet SMD adhesives from stencils and misprinted PCBs. 440R SMT Detergent is distributed worldwide by SMarT Sonic SMT Detergent Corp.--- ELECTRONICS TRADING & MFG CO., LTD. from facilities in California and the U.K.
