Aqueous Technologies' StencilWasher ECO is an economical tool designed specifically to clean stencils. 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.

StencilWasher ECO is equipped with many standard features including:

Low discharge configuration (closed-loop wash, filtered discharge rinse)
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.
