Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0035] Such as Figure 1~Figure 7 As shown, a quartz crystal resonator with a circular wafer structure includes a quartz wafer 10 , a package cover 20 and a package base 30 . The quartz wafer 10 includes a circular member 11 , a connecting portion 12 and a protective frame 13 , the protective frame 13 is in the shape of a rectangle, and plays the role of support, packaging and connection. The circular member 11 is arranged at the center of the protective frame 13 and can vibrate freely. The circular member 11 is connected with a short frame of the protective frame 13 through the connecting portion 12. When the protective frame 13 is subjected to an external force, the force will not Transfer to the circular member 11, thereby protecting the circular member 11 well.

Abstract

The present invention relates to a quartz crystal resonator with a circular wafer structure. The quartz crystal resonator is packaged by a quartz wafer (10), a packaging cover (20) and a packaging base (30). The quartz wafer (10) includes a circular member (11), a connecting part (12) and a protection frame (13). The circular member (11) can oscillate freely in a packaged cavity and is provided with an electrode area (14). The connecting part (12) and the protection frame (13) are provided with a metal layer A (15). A positioning hole (16) in the protection frame (13) is internally provided with a metal layer B (17). The packaging base (30) is provided with a pin (31). The electrode area (14) is electrically connected with the pin (31) by using the metal layer A (15) and the metal layer B (17). The present invention also discloses a manufacture method of the quartz crystal resonator with the circular wafer structure. The manufacture method can be used for mass production of small resonators at low cost, and can enhance center energy trapping effect of the quartz wafer and improve product consistency remarkably.

Description

technical field [0001] The invention relates to the technical field of quartz crystal resonators, in particular to a quartz crystal resonator with a circular wafer structure and a manufacturing method thereof. Background technique [0002] Quartz crystal resonators are usually composed of piezoelectric quartz wafers and packaging shells, and the packaging shell materials are ceramics, glass, etc. Electrodes need to be vapor-deposited on the upper and lower sides of the piezoelectric quartz wafer, and the electrodes are connected to the base pins in the package shell through the leads of the sealed package. The AC voltage can be connected to the upper and lower electrodes of the quartz wafer through the pins, so that the quartz wafer produces an inverse piezoelectric effect, thereby generating oscillation. Quartz crystal resonators are widely used in electronic industries such as mobile electronic equipment, mobile phones, and mobile communication devices due to their freque...
