Ultrasonic Stencil Cleaning
Smart Sonic offers a wide array of ultrasonic equipment, from fully automatic stencil cleaners to semi-automatic stencil cleaners.
Smart Sonic Stencil Cleaners are able to clean any type of solder paste from any fine pitch stencil, at the same time its low power density is safe for cleaning misprinted PCBs and pallets. Its low-temperature cleaning conserves energy and protects stencils from heat distortion and adhesive failure.
All Smart Sonics Stencil Cleaners are able to communicate with an EnviroGuard System or a Smart Sonic Evaporator. This provides for a more automated and environmentally friendly Closed-loop Stencil Cleaning System.
SMT Detergent
Smart Sonic’s 440-R SMT Detergent is the workhorse of the Smart Sonic Process. 440-R is an effective chemistry for cleaning all types of solder paste.
More importantly, 440-R does not contain any Volatile Organic Compounds (Zero-VOC), which means that Smart Sonic is able to treat the wastewater through evaporation or through resin filters.
Other SMT detergents contain volatile compounds which are hazardous to evaporate or require more complex wastewater filtration.
Water Treatment
Smart Sonic provides two methods for treating SMT wastewater. Our most popular method is with the Model EZ-0 and the Model SE-1 evaporators. Wastewater is heated and evaporated through an exhaust duct. After the water is evaporated, you can easily dispose of the remaining solids.
Smart Sonic offers wastewater treatment through carbon and resin filters with our EnvrioGuard System. Our filter will catch any solder paste or harmful chemicals, and it can provide an additional source for Deionized (DI) water. This method is more popular where our clients don’t have a suitable means to exhaust vapor for an evaporator or have limited access to DI water.
