Abstract
The utility model relates to a thin metal package ceramic quartz-crystal resonator, comprising a ceramic base and a metal upper cover, wherein the ceramic base is internally provided with a quartz chip with an electrode; the electrode of the quartz chip is electrically connected with an inner electrode of the ceramic base; the inner electrode of the ceramic base is connected with an outer electrode of the ceramic base through an inner line of the ceramic base; a welding material for sealing the ceramic base and the metal upper cover is electroplated on the surface of the metal upper cover and the surface of the ceramic base in contact with the metal upper cover; and the volume of the quartz-crystal resonator is 2.0*1.6*0.35mm. The thin metal package ceramic quartz-crystal resonator disclosed by the utility model utilizes a reduced ceramic base, metal seal cover and quartz chip, largely reduces the volume of the crystal resonator, and packs the welding material electroplated on the surface of the metal seal cover and the contact ceramic base, thereby keeping high-frequency precision and stability, and excellent sealing performance.
Description
Technical field
The utility model relates to a kind of quartz-crystal resonator, particularly relates to a kind of thin metal packaging ceramic quartz-crystal resonator.
Background technology
Along with the fast development of miniature electronic product, manufacturer proposes the crystal oscillator demand of slimming more, and previous product can not satisfy customer need, and therefore the technology in design, in the manufacturing is the important key that need overcome.
Summary of the invention
The utility model technical problem to be solved provides a kind of metallic packaging crystal oscillator, can satisfy the application demand of miniature electronic produce market.
The utility model solves the technical scheme that its technical problem adopted: a kind of thin metal packaging ceramic quartz-crystal resonator is provided, comprises base of ceramic and metal top cover, be placed with the quartz chip that has electrode in the said base of ceramic; Electrode on the said quartz chip is realized being electrically connected with the internal electrode of base of ceramic; The internal electrode of said base of ceramic links to each other with the outer electrode of base of ceramic through the internal wiring of base of ceramic; Said metal top cover surface and the base of ceramic electroplating surface that contacts with metal top cover are useful on the welding material of involution base of ceramic and metal top cover; The volume of said quartz-crystal resonator is 2.0 * 1.6 * 0.35mm.
Electrode on the said quartz chip links to each other through conducting resinl with the internal electrode of base of ceramic.
