StencilWasher ZDO
Zero Discharge
Ultrasonic Stencil & Misprint Cleaning System

Cleaning at the Speed of Sound
Aqueous Technologies' StencilWasher ZDO is fully closed-loop (zero discharge). It utilizes precisely controlled sound waves to remove un-reflowed solder paste from stencils, screens and misprints. At 40 kHz, the ultrasonic energy is gentle enough not to damage delicate parts yet is highly effective in the removal of dried pastes on fine-pitch stencils. The built-in ultrasonic "sweep" generator oscillates the cleaning frequency between 37 kHz and 43 kHz, preventing damage to wire bonds and other delicate devices.

StencilWasher ZDO is capable of cleaning stencils or misprints up to 29" x 29" in size (full immersion).

StencilWasher ZDO is equipped with many standard features including:

  • Zero discharge configuration for wash and rinse sections
  • Programmable digital wash cycle timer 
  • Safe 31 watts per liter power ratio 
  • Wash solution heating system with programmable digital temperature controller 
  • Wash solution solder paste filtration system with stainless steel housing
  • Rinse water solder paste filtration system with stainless steel housing
  • Hand-held rinse wand
  • Hand-held airknife
  • Fully enclosed (cabinetized) 
  • Ten year limited transducer warranty
  • StencilWasher ZDO is designed to remove all solder-paste types and incurred adhesives in cycle times averaging less then five minutes while directing no fluids to the drain.
