Problems solved by technology

[0004] The ceramic package or base is a laminated ceramic structure that comprehensively applies technologies such as metal overfire deposition, metal mixing, and ceramic-metal sealing. Such ceramic components require high-tech production, are relatively expensive, and have always been relatively scarce. goods
Therefore, the production bottleneck of the currently used ceramic packaged quartz crystal resonators lies in the ceramic components

Embodiment Construction

[0051] FIG. 1 shows a rectangular piezoelectric quartz crystal resonator plate 10 . In the present invention, the long side of the resonator plate 10 is parallel to the X-axis, which is just the crystal characteristic axis and the AT cutting direction of the quartz crystal, and this AT-cut quartz crystal is generally used for high-frequency quartz crystal resonance device. The width of the resonator plate 10 is parallel to the Z' axis, and the thickness is parallel to the Y' axis.

[0052] In order not to specifically limit the present invention, the common size of the resonator piece 10 includes the length range: between 0.5mm-12mm, such as 7.5mm. Width range: between 0.5mm-5.5mm, such as 5mm. The thickness depends on the resonant frequency according to the following relationship

[0053] t=1.67 / F (Formula 1)

[0054] t stands for thickness, unit mm, F stands for resonant frequency, single MHz, the resonant frequency is usually between 1MHz-200MHz.

[0055] In order to p...

Abstract

The invention relates to an all silica crystal resonator and a new manufacture method thereof, wherein the all silica crystal resonator comprises a group of resonance plates, wherein the resonance plates are fixed by each base on a base big sheet and are sealed by each outer shell on an outer shell big sheet, a group of resonators are manufactured simultaneously in the manufacture process and are finally decomposed into single resonators, which enables the processing and manufacture process to be simple, the manufacture cost is lowered, and the efficiency is improved. The resonance plates, the outer shell big sheet and the base big sheet are made of quartz crystal materials, the use of ceramic packaging objects is avoided, the problem which is caused by the ceramic packaging objects and by any relations with the ceramic packaging objects or the bases are also avoided, and the service life of the silica crystal resonator is prolonged.

Description

technical field [0001] The invention relates to a method for manufacturing a quartz crystal resonator and the resonator thereof. Specifically, the invention relates to a surface-mounted quartz crystal resonator and a new manufacturing method thereof. Background technique [0002] Due to its frequency accuracy and stability, quartz crystal resonators are an indispensable part of modern electronic industries such as communications, computers, entertainment equipment and other fields as we know them. So far, quartz crystal resonators are usually composed of piezoelectric quartz crystal thin plate basic units, such as circular or rectangular, and a package that can be sealed by some method. The AC voltage can be applied to the basic unit of the quartz crystal sheet to oscillate through the leads passing through the hermetically sealed package. On the basic unit of the piezoelectric quartz crystal sheet, a group of very thin conductive metal electrodes are deposited on its two m...
