Abstract:
A method for producing an encapsulation for a surface acoustic wave (SAW) component having a substrate and SAW component structures on the substrate, which comprises:producing a cap by providing a plastic frame-shaped carrier directly on the component substrate with a first photoresist layer applied directly on the component substrate, the carrier accommodating and surrounding the SAW component structures such that at least one cutout is placed in a region of the SAW component structures for accommodating the SAW component structures within the at least one cutout and covering the carrier with a second photoresist layer to encapsulate the SAW component structures on the substrate with the cap; and directly encapsulating the cap covering the SAW component structures onto the substrate with a plastic sheath by a sheathing process that is selected from dipping, sintering, potting, extrusion coating and press coating, using plastic components on a base of reactive resin or melted thermoplastics.
