Abstract:
Encapsulated surface wave component comprising:a surface wave device on an active surface of a piezoelectric substrate, said surface wave device comprising interdigital electrodes linked to conducting buses; a base comprising electrodes linked to external conducting pads; wherein the active surface of the surface wave device is assembled to the base by a conductive adhesive which is anisotropic along an axis Z, perpendicular to a plane of the surface wave device, at a level of the conducting buses opposite the electrodes of the base in such a way as to provide for electrical connections, the electrodes of the base having structures in relief constituting barriers against creeping of the anisotropic conductive adhesive towards active zones of the surface wave device, with local thickenings configured to compress the anisotropic conductive adhesive locally.
