Electric-resistance-welded small size quartz-crystal resonator with one-end-fixed chip

Abstract

The invention discloses an electric-resistance-welded small size quartz-crystal resonator with a one-end-fixed chip. The quartz-crystal resonator comprises a cavity shell consisting of a substrate and a shell. A silver electrode quartz plate, a base and spring pieces are arranged in the cavity shell. The base comprises two glass insulators arranged at the bottom of the substrate, and two lead terminals penetrating through the two glass insulators. Each of the two lead terminals consists of a pin head part and a lead foot part. The silver electrode quartz plate is fixed on the spring pieces through two conductive adhesives. The spring pieces are bonded on two sides of one end of the quartz plate by the conductive adhesives. The quartz-crystal resonator has the advantages that vibration areas during the resonance process of the silver electrode quartz plate are enlarged, affects caused by boundary effect are decreased, resonance resistance of the quartz-crystal resonator can be reduced efficiently, and requirements of work stability are met.

technical field [0001] The invention relates to a quartz crystal resonator, in particular to a small resistance-welded quartz crystal resonator with one end of the chip fixed. 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,...

AI Technical Summary

Problems solved by technology

When the volume of the quartz crystal resonator is miniaturized, since the two ends of the silver electrode quartz wafer are respectively fixed by the spring piece through the conductive glue, the vibration area during the resonance process of the silver electrode quartz wafer is reduced, and the influence of the boundary effect is increased. As a result, the resonance internal resistance of the quartz crystal resonator increases sharply, and even fails to work
