Abstract

The invention provides a laminated assembly structure and method of a quartz crystal resonator and the resonator, and belongs to the technical field of resonators. According to the invention, throughlaminated arrangement of the buffer wafer and the frequency output wafer, the buffer wafer can buffer the stress transmitted to the frequency output wafer by the resonator base and the reed, the stability of the frequency output wafer is ensured, and thus the accuracy of the frequency of the quartz crystal resonator is ensured; meanwhile, the assembling mode is simple, operation is convenient, cost can be reduced, and assembling efficiency is improved; compared with a quartz crystal resonator of a traditional structure, the quartz crystal resonator has the advantages that the characteristics such as the size, the shape, the power consumption, the assembly process, the practicability and the reliability can be kept consistent, and the acceleration sensitivity index can be obviously optimized to 2.0 E<-10> / g to 5.0 E<-10> / g.

Description

technical field [0001] The invention belongs to the technical field of resonators, and more specifically relates to a stacked assembly structure and method of a quartz crystal resonator and a resonator. Background technique [0002] The resonator is an electronic component that generates a resonant frequency. It mainly plays the role of frequency control and has the characteristics of stability and good anti-interference performance. All electronic products require resonators for frequency transmission and reception, so resonators are widely used in various electronic products. middle. [0003] Acceleration sensitivity is an important parameter of a resonator. Acceleration sensitivity is a vector, that is, when the acceleration is along the direction of the acceleration vector, the frequency shift caused by acceleration is the largest. For quartz crystal resonators, the principle of frequency shift effect caused by acceleration is: acceleration→stress→strain→frequency shif...
