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).

• Zero discharge configuration for wash and rinse sections
• Programmable digital wash cycle timer
• Safe 31 watts per liter power ratio
