Problems solved by technology

The resistance welding packaging method has been very mature in China. The resistance welding packaging method has been widely used in the processing of miniaturized quartz crystal resonators. During the airtight packaging process, the vibration and pressure deformation of the quartz crystal resonator can easily cause the glass insulator to break and cause poor airtightness
In addition, when the quartz crystal resonator packaged by resis

Example Embodiment

[0027] Hereinafter, the recessed metal base resistance welding miniature quartz crystal resonator of the present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0028] See Figure 1 to Figure 6 As shown, a recessed metal base resistance-welded miniature quartz crystal resonator according to an embodiment of the present invention includes a metal base 10, a cover sheet 20, a silver electrode crystal 30, conductive glue 40, and glass insulation. The seed 50 and the lead terminal 60. The metal base 10 is a structure with a cavity space, and the upper edge 12 of the metal base 10 extends outward so that the entire metal base 10 forms a recessed cavity space structure. The upper edge 12 and The cover sheet 20 is sealed and welded, the bottom of the recessed metal base 10 and the glass insulating seed 50 form a recessed surface, and the silver electrode crystal 30 is in the recessed cavity.

[0029] The base 10, the glass insu...

Abstract

The invention relates to a sunken type metal base electric resistance welding minitype quartz-crystal resonator. The quartz-crystal resonator comprises a metal base, a cover plate, a silver electrode quartz plate, a conductive adhesive, glass insulators and a lead terminal. The metal base is of a structure with a hollow cavity space, the upper edge of the metal base extends outwards so that the sunken type hollow cavity space is formed in the overall metal base, the upper edge is welded with the cover plate in a sealing mode, a sunken surface is formed by the bottom portion of the sunken type metal base and the glass insulators, and the silver electrode quartz plate is arranged inside the sunken type hollow cavity. According to the sunken type metal base electric resistance welding minitype quartz-crystal resonator, a cavity body is formed by sinking of the metal base, a welding face packaged between the upper portion of the sunken type metal base and the cover plate in an electric resistance welding mode is not located in the same plane as the two glass insulators, effects, caused by vibration and pressure deformation of the quartz-crystal resonator, on the glass insulators in an electric resistance welding air-tight packaging process are effectively reduced, and good air tightness is ensured.

Description

technical field [0001] The invention relates to a quartz crystal resonator, in particular to a sunken metal base resistance welding miniature quartz crystal resonator. Background technique [0002] Quartz crystal resonators are essential frequency selection and control core components in modern electronics and communication technology. It is widely used in military and civilian products, such as communications, navigation, quartz clocks, color TVs, computers and terminal equipment, various boards, etc. [0003] With the development of microelectronics technology and the popularization of integrated circuits, the requirements of the positive electrode for various components are not only limited to the electrical performance, but also the volume and height requirements of the components are becoming more and more stringent, requiring components to be miniaturized , SMD type. The quartz crystal resonator is a component that is not suitable for an integrated structure, but it ...
