Abstract:
Leiterplatte umfassend, einen Schaltungsträger (1), eine Deckschicht aus einem nicht leitenden Material (4), welches eine organische Substanz umfasst, angeordnet auf dem Schaltungsträger (1), eine erste Metallisierungsebene (5) zumindest teilweise angeordnet auf der Deckschicht (4), wobei die erste Metallisierungsebene (5) einen flexiblen Bereich (10) aufweist.
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.
