The Model 6000 reduces chemical consumption and wastewater by 40% yet increases ultrasonic energy efficiency over Smart Sonic�s previous automatic stencil cleaners. The newly designed cleaning tanks are modular and can clean 29-inch stencils but only use 34 gallons of wash water per two-week maintenance cycle compared to 57 gallons every two weeks for the previous automatic systems. In addition, the Model 6000 requires only 3.4 gallons of 440-R� SMT Detergent to establish a 10% wash solution compared to 5.7 gallons for previous models.
The new modular tank design enables using the Model 6000 to perform multiple cleaning applications. An ambient wash tank is provided as standard equipment for the safe cleaning of solder paste from stencils and misprinted PCBs. However, an additional heated wash tank may be incorporated for cleaning flux residue from pallets and oven radiators or SMD adhesives from stencils and misprinted substrates - all within the same footprint of the previous single application machines. A touch-pad controller stores multiple programmable cleaning profiles to facilitate easy one-button operation for all users.
Ergonomics has also been improved by reducing the loading / unloading height from 52-inches down to a 36-inch level. Located directly below the loading/unloading station is a built-in drying rack to allow up to three 29-inch stencils to air dry naturally. If automatic drying is required, this area can be converted into a unique low-temperature dryer to safely dry stencils automatically without exposing the stencil to high temperatures that could weaken the bond of the heat-cured adhesives used to attach the screen to the frame and etched foil. Low-temperature drying also prevents distortion of fine-pitch apertures and screen tension problems due to irregular expansion and contractions.
The Smart Sonic Stencil Cleaning Process is guaranteed to clean any type of solder paste from any fine-pitch stencil and the Environmental Protection Agency (EPA) certifies the Smart Sonic process environmentally safe, user safe and effective, which makes it ISO 14000 and MP&M Guideline compliant.
