A fluid treating device with at least one chamber, a plurality of ultrasonic transducers for imparting ultrasonic waves through fluid when present in the at least one chamber; a screen located in the at least one chamber wherein the screen is coated with a dielectric material. The coated screen diffuses the ultrasonic waves and enhances uniform treatment. The fluid treating device is useful for treatments such as cleaning, degreasing, plating or etching articles such as ceramic substrates.

Fluid treatment device and method

A liquid flux using water instead of a volatile organic compound as the liquid carrier is used in a wave soldering process. Undesirable formation of solder balls, solder bridges and solder webbing is prevented by using an air knife to direct a vigorous jet of gas at the dielectric substrate in the preheating section.
