Embodiment Construction

[0022] Embodiments of the present invention will be further explained in conjunction with related figures below. Wherever possible, the same reference numerals have been used in the drawings and description to refer to the same or similar components. In the drawings, the shape and thickness may be exaggerated for the sake of simplification and convenient labeling. It should be understood that elements not particularly shown in the drawings or described in the specification are forms known to those skilled in the art. Those skilled in the art can make various changes and modifications according to the content of the present invention.

[0023] When an element is referred to as being "on", it can generally mean that the element is directly on the other element, or there may be other elements present in both. Conversely, when an element is referred to as being "directly on" another element, it cannot have the other element present between the two. As used herein, the word "and...

Abstract

The invention discloses a crystal oscillator packaging structure. The crystal oscillator packaging structure comprises a packaging base, a resonance crystal wafer and a top cover. The top of the packaging base is provided with a groove, and the side wall of the packaging base surrounds the groove. The resonance crystal wafer comprises a frame area, a U-shaped connecting area, a resonance area and a first connecting arm. The U-shaped connecting area is connected between the edge of the resonance area and the frame area, a notch of the U-shaped connecting area and two mutually perpendicular inner side walls face the resonance area, the first connecting arm is connected between the U-shaped connecting area and the frame area, and the frame area is arranged on the side wall of the packaging base. The top cover is arranged on the frame area to shield the groove, the U-shaped connecting area, the resonance area and the first connecting arm. The U-shaped connecting area is formed between the frame area and the resonance area, so that external mechanical vibration or instant impact is prevented from being transmitted to the resonance crystal wafer, and the resonance frequency is stabilized.

Description

technical field [0001] The present invention relates to a packaging structure, and in particular to a crystal oscillator packaging structure. Background technique [0002] Quartz elements have stable piezoelectric characteristics, which can provide accurate and wide reference frequency, clock control, timing function and noise filtering functions. In addition, quartz elements can also be used as vibration and pressure sensors, as well as important optical components; Therefore, for electronic products, quartz components play a pivotal role. [0003] figure 1 A schematic diagram of a prior art quartz vibrator. see figure 1 A quartz vibrator 1 is composed of a quartz vibrator element 10 and a first case 11 and a second case 12 that cover the quartz vibrator element 10 . The quartz vibrator element 10 is composed of a quartz substrate. Excitation electrodes 13 and 14 are formed on the upper and lower surfaces of the quartz oscillator element 10, and the quartz oscillator e...
