Embodiment Construction

[0020] according to figure 1 The upper part of the OFW device system contains a piezoelectric substrate 1 and the above-mentioned conductive structure 2 , a connection plane 3 - pad - and a frame 4 surrounding the conductive structure 2 and the connection plane 3 . The conductive structure 2 can form, for example, an interdigital transducer, a resonator or a reflector.

[0021] For the sake of clarity, a larger number of device systems in the above-mentioned technologies can be located on one substrate at the same time, in figure 1 The central body 1 is exposed to the left and to the right by a vertical line A, in which a part of the frame 4 is also indicated.

[0022] In addition, there is a printed circuit board 5 on which side rails 6 perpendicular to the component system and contact elements 7 —pumps — are located thereon. In order to indicate a greater number of components, the printed circuit board is extended outwards by a line A.

Abstract

An OFW component with a component system (1-3) mounted by the flip-chip technique onto a printed circuit board (5) and with a frame (4) surrounding the component structures (1-3), in which conductive tracks (6, 8) are interconnected on the printed circuit board (5) by this through connection (9-1, 9-2, 9-3) in such a way that components (9-1, 9-2) running in the direction of their extension are mutually staggered and interconnected via a connecting member (9-3).

Description

technical field [0001] The above invention relates to electronic devices, especially devices that operate with surface acoustic waves - OFW devices. Background technique [0002] The electronic device of the prior art is advantageous because the base body of the device, the frame between the base body and the printed circuit board surrounding the printed circuit board and the conductive structures already constitute a complete package often referred to as a "chip size package". shell. "Printed circuit board" in the above-mentioned invention is understood to be a support on a plastic and ceramic basis that rises from the guide rails, respectively. The problem here, however, is that the electrical connection between the rails on opposite sides of the printed circuit board has to be made through the printed circuit board, so that problems of leaks caused by the enclosure formed by said components can arise, so for example Water vapor may damage or destroy the function of the ...
