Westlake Village, CA — From the makers of Smart Sonic stencil clean- ers and 440-R SMT detergent, Nano Stencil Clean™ was formulated specifically to safely clean all types of solder paste from nano-coated sten- cils and misprinted PCBs. The new technology of applying


a nanocoating to solder paste stencils has shown significant advances toward improving print yields. However, many of the nano-chem - istries used to provide a hydrophobic and oleophobic surface to the aper- tures and underside of the stencil are sensitive to elevated pH cleaning chemistries. Until the introduction of Nano Stencil Clean, manufacturers of cleaning chemicals would often recommend a common “pH neutral” cleaning chemistry. The pH neutral cleaner would


have less ill effects on the nanocoat- ing. But, because the pH neutral product was not designed to clean solder paste, it was less effective when removing solder paste from the nano-coated stencil. In addition, because solvents

have a neutral pH, many of these pH neutral products obtain their neutral pH by mixing solvents into a little water and calling it a “water-based” chemistry. These pH neutral prod- ucts often have a strong solvent odor and are environmentally problematic due to high VOC content. Nano Stencil Clean is a true


water-based cleaning chemistry designed specifically to safely clean all types of solder paste from nano- coated stencils. Nano Stencil Clean is environmentally safe and safe to use
