Abstract

See full text

A piezoelectric filter and the process of making the same in which the filter is enclosed in a capsule or envelope of dielectric material through which the connection for the electrodes extend. Self adhesive spacers on each principal surface of the piezoelectric filter are embossed to provide a spacing for the electrodes with respect to the envelope. In addition, slots or other openings between the embossed areas permit the envelope material to engage a surface of the filter that does not have an electrode for damping purposes. The process of manufacture is dictated by the structure and requires first the placement of the spacer in position with the enclosed areas registering with the electrodes and then the formation of the envelope.
