Abstract

The invention discloses an aging performance test device and method for a quartz-crystal resonator. The aging performance test device for the quartz-crystal resonator comprises a shell with an openingin the bottom, an output switching base at the bottom of the shell, a signal processing and debugging function universal base plate and an oscillating and heating temperature control function adaptive plug board, wherein the signal processing and debugging function universal base plate is located in the shell and fixedly combined with the output switching base; the oscillating and heating temperature control function adaptive plug board is located on the portion, above the signal processing and debugging function universal base plate, in the shell. The aging performance test method comprisesthe steps that the quartz-crystal resonator is plugged in the oscillating and heating temperature control function adaptive plug board; the oscillating and heating temperature control function adaptive plug board is inserted into the signal processing and debugging function universal base plate; the aging performance test device obtained after plug-in mounting is completed is installed in an agingtest system, powered on and debugged; aging performance testing is conducted; the quartz-crystal resonator is dismounted. By means of the aging performance test device and method, the problems are solved that by means of an existing method, the product morphology is damaged, and the product adaptability is poor.

Description

technical field [0001] The invention relates to the technical field of component testing. More specifically, it relates to an aging performance testing device and method for a quartz crystal resonator. Background technique [0002] Quartz crystal resonator is a resonant element made of quartz wafer with piezoelectric effect, and it is also a key component of crystal oscillator. Quartz crystal resonators are widely used in communication, medical, aerospace, weaponry and other industries and fields due to their small size, light weight, high reliability, and excellent frequency stability. [0003] The frequency of quartz crystal components such as crystal resonators and crystal oscillators changes with time, which is called aging. Aging performance is an important index to evaluate the frequency stability of quartz crystal components. And when the crystal resonator is used as a key component of the crystal oscillator, the aging performance of the crystal resonator itself ha...
