Abstract: In a process for manufacturing a surface-wave filter, a carrier plate 10 which can be subdivided into base plates 2 is provided with printed circuits in each base plate zone A and these are contacted with the active structures of surface-wave chips 1 by a flip-chip technique. A metal or plastic foil 3 or 4 is then laid on the carrier plate 10 fitted with chips and then processed under heat and pressure, for example, so that each chip 1 - except for the chip surface facing the carrier plate 10 - is enveloped and hermetically sealed on the carrier plate surface in the zones between the chips.

Abstract: A method is provided for manufacturing a saw filter in which a carrier plate 10 that can be separated into base plates 2 is respectively provided with interconnects in the base plate regions A and these are contacted to the active structures of SAW chips 1 in flip-chip technique. A metal foil 3 or plastic film 4 is placed onto the chip-equipped carrier plate 10 and, for example, is pressure and heat treated such that it envelopes each chip 1 (except for the chip surface facing toward the carrier plate 10) and lies hermetically tight on the carrier plate surface in regions between the chips.
