Abstract
Apparatus and methods for selectively coating the surfaces of objects are disclosed. The apparatus comprises a plurality of megasonic transducers which generate acoustical pressure waves in the megasonic frequency range in an upward direction and cause droplets of coating material to be expelled from a supply of the liquid coating material which is disposed above the transducers. The droplets travel in a generally upward direction toward the surface of the object to be coated which is held in an inverted, i.e., downward position.
