StencilWasher ECO
Low-Cost Stencil and Misprint Cleaning System

Aqueous Technologies' StencilWasher ECO 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 ECO is capable of cleaning stencils or misprints up to 29" x 29" in size (29" width x 26" immersion depth)

While StencilWasher ECO represents the entry-level model, it is still packed with valuable features including:

  • Programmable wash cycle timer 
  • Safe 31 watts per liter power ratio 
  • Wash solution filtration system with stainless steel housing
  • Rinse water filtration system with stainless steel housing
  • Hand-held rinse wand
  • Hand-held airknife
  • Fully enclosed (cabinetized) 
  • Ten year limited transducer warranty

StencilWasher ECO is designed to remove all solder-paste types in cycle times averaging less than five minutes.
