New and improved ultrasonic spray shaping assemblies, components thereof, and methods for using the assemblies. An ultrasonic spray shaping assembly includes jet block and impact jet components to receive and redirect a single gas stream, whereby to use the single gas stream to shape an ultrasonic spray plume in a desired shape, particularly into a desired width of the plume. Modifications to the components, such as relative positioning, can be used to alter the shape of the spray plume. The present invention can be fabricated in a compact, lightweight design. It has many applications, including but not limited to, the deposition of flux onto a printed circuit board. |
