Abstract

Elektronisk komponent (10) med piezoelektriske egenskaper og konstruert for å innstille godhetsfaktoren (Qm) av komponentens piezoelektriske resonatorer (20), selv om resonatorenes piezoelektriske materiale er av allment til-gjengelig type. Komponenten er bygget opp med et underliggende substrat (12) med mnsterelektroder (16, 18; 90, 92, 94, 96). Elektrisk ledende bæreelementer (40) er lagt på mønsterelektrodene for å bære resonatorene (20). Overflateelektroder (30, 32 ) for utvendig tilkopling er koplet til mønsterelektrodene via bæreelementene, og gap mellom resonatorene (20) og substratet (12) er fylt med et gummilignende elastisk materiale (42). Et annet til-svarende materiale (44) er lagt på den ene av resonatorenes overflate, nemlig den overflate som vender oppover når resonatoren er montert på substratet. Alternativt brukes bare det ene av disse materialer (42, 44).Electronic component (10) with piezoelectric properties and designed to set the goodness factor (Qm) of the component's piezoelectric resonators (20), even though the piezoelectric material of the resonators is of a generally available type. The component is built up with an underlying substrate (12) with pattern electrodes (16, 18; 90, 92, 94, 96). Electrically conductive support elements (40) are placed on the pattern electrodes to support the resonators (20). Surface electrodes (30, 32) for external connection are connected to the pattern electrodes via the support elements, and gaps between the resonators (20) and the substrate (12) are filled with a rubber-like elastic material (42). Another corresponding material (44) is laid on one of the surfaces of the resonators, namely the surface facing upwards when the resonator is mounted on the substrate. Alternatively, only one of these materials is used (42, 44).
