Aqueous Technologies to Exhibit StencilWasher-ECO at APEX 2009

Rancho Cucamonga, CA - March 2009 � Aqueous Technologies Corp. announces that it will exhibit the StencilWasher-ECO semi-automatic stencil cleaner for solder paste removal in booth 2247 at the upcoming IPC/APEX exhibition and conference scheduled to take place March 31-April 2, 2009 in Las Vegas.

StencilWasher-ECO is part of Aqueous Technologies' ultrasonic technology that uses precisely controlled sound waves to remove un-reflowed solder paste from stencils, screens and misprints.�Unlike other technologies that can damage delicate stencils, ultrasonic energy is gentle enough not to damage delicate parts, but is highly effective in removing even dried pastes on fine-pitch stencils.�

Aqueous Technologies' semi-automatic ultrasonic stencil cleaning system is designed to accommodate stencils, screens or misprinted assemblies up to 29 x 29" (736 x 736 mm), and it features a 25" (63.5 cm) immersion depth.

StencilWasher-ECO provides fast and efficient solder paste removal at a very economical price. The stencil washer is designed to remove all solder paste types and provides wash, rinse and dry functions. The washer features a stainless steel wash and rinse tank, and a stainless steel deck.

StencilWasher-ECO has a programmable wash cycle timer for consistent operation. In addition to a washing function, the system is equipped with a handheld rinse wand and airknife.

Multiple side-mounted 40 kHz transducers target effective cleaning power onto the stencil or misprint.
