Abstract:
A method of applying a matching layer to a transducer, comprising the steps of:fixing a stencil to the transducer so that a surface of the transducer is accessible through an opening of the stencil; placing a bead of matching layer material on the stencil at a predetermined distance from the stencil opening; situating a blade adjacent the bead such that an edge of the blade contacts the stencil and the bead lies between the blade and the opening; initiating relative sliding motion, under atmospheric conditions, in a first direction between the transducer surface and the edge of the blade; and initiating relative sliding motion, under vacuum conditions, in a second direction between the transducer surface and the edge of the blade, wherein the second direction is opposite to the first direction.
