The new approach is offered for the cleaning applications of electronics modules. The modular systems of the distributed ultrasonics converters, which are established in chessboard order, provide the uniformity cavitation fields in ultrasonic bath. The effect of periodic deviation of ultrasonics frequency created the directed acoustic currents in the liquid, witch increase removal pollution process. The technological parameters of automated ultrasonics cleaning lines as concentration SAS, temperature of washing solutions, and ultrasonics cavitation power are optimized.
