Stencil Cleaning


Cleaning medium for SMT stencil printer wipe systems

ZESTRON® SW is a solvent-based cleaner with a high flash point, which was specifically designed for the use in SMT printers without vacuum drying. ZESTRON® SW achieves reproducible cleaning results and dries residue-free, thus it increases the reliability of the printing process. 

Advantages compared to other underside wiping cleaners:

  • Due to its wide process window ZESTRON® SW reliably removes solder pastes from the stencil underside
  • Dries fast and residue-free on stencils after dry wipe
  • Good delineation stability and reduced solder balling
  • Unlike Isopropanol (flash point: 12°C/54°F) ZESTRON® SW (flash point: 67°C/153°F) dramatically increases operational safety while operating stencil printing equipment
  • Based on non-halogen, organic solvents
  • Biodegradable
  • Reduces the amount of cleaning cycles
