Problems solved by technology

[0007] Although this technical solution solves the problem of temperature sensing consistency, it has high requirements for the setting position of each module, which is not conducive to the generalization of products. At the same time, it increases the thickness of the crystal oscillator, which will affect the thinness of the product to which it is applied. change

Abstract

The invention discloses a method for improving the temperature accuracy of a crystal oscillator. A substrate is at least provided with a crystal, a temperature control module and a temperature sensor in a disperse mode, and the interval among the crystal, the temperature control module and the temperature sensor is filled with filling materials with a good heat-conducting property, so that the temperature of the temperature control module and the temperature of the temperature sensor tend to be consistent. The invention further discloses the crystal oscillator and a packaging method of the crystal oscillator. The crystal, the temperature sensor, a heating module and the temperature control module are arranged on the same plane in a disperse mode, so that the thickness of the crystal oscillator is conveniently reduced, the intervals among the modules are filled with the filling materials with the good heat-conducting property, the modules are heated more evenly, the temperature of the modules tend to be consistent, the temperature control precision is improved, the compensation dosage is output more accurately, and the frequency temperature stability of the crystal oscillator is improved.

Description

technical field [0001] The invention relates to the technical field of crystal oscillators, in particular to a method for improving the temperature accuracy of a crystal oscillator, an oscillator and a packaging method thereof. Background technique [0002] Crystal oscillator is a high-precision and high-stability oscillator, which is widely used in various oscillating circuits such as color TVs, computers, and remote controls. It is used in frequency generators in communication systems to generate clock signals for data processing equipment. and provide a reference signal for a particular system. [0003] Temperature-compensated crystal oscillator, as a clock source with excellent performance, is very popular in high-end electronic products. Its biggest advantage is that it can keep the output frequency stable at any temperature, so that it can ensure that electronic products will not work Ambient temperature is limited. [0004] Such as figure 1 Shown is a structure of ...
