AI Technical Summary

Technical Problem

Existing SMD crystal oscillator aging test equipment cannot effectively simulate its actual working environment in a confined space and humid weather conditions, resulting in test results that cannot accurately assess its long-term stability and reliability.

Method used

A device comprising a test chamber, a capsule-shaped storage module, a sealing cover, and a steam element was designed. The sealing cover is driven by a cylinder to approach the capsule-shaped storage module to form a sealed space, and the steam element is used to simulate a humid and hot environment, directly introducing steam into the sealing cover to contact the crystal oscillator, simulating the real working state of the crystal oscillator in electronic devices.

Benefits of technology

This study provides a more accurate assessment of the long-term stability and reliability of SMD crystal oscillators in enclosed spaces and humid and hot environments, offering more valuable test results and improving the comprehensiveness and effectiveness of the tests.

Abstract

The utility model provides a power-up aging device for an SMD crystal oscillator. The power-up aging device comprises a test box and a steam piece, a bag-type storage module and a sealing cover are arranged in the test box, an air cylinder for driving the sealing cover to be close to or away from the bag-type storage module is mounted on the test box, and an air supply part for supplying air into the bag-type storage module is mounted on the back surface of the test box; and the steam piece is used for guiding steam into the test box and the steam piece. According to the SMD crystal oscillator power-up aging device provided by the utility model, the sealed working environment of the crystal oscillator is simulated through the capsule type object placing module and the sealing cover, the size of the capsule cylinder is adjusted and the capsule cylinder is sealed through the air supply member and the tubular shunting member, the capsule cylinder is close to the real state, and the first air guide pipe of the steam member is utilized to guide steam into the test box to simulate the humid and hot environment, thereby making up the defects of the traditional method. And steam is introduced into the sealing cover through the second gas guide pipe to directly contact with the crystal oscillator, so that the test effect is enhanced, and the reliability of the crystal oscillator in a severe environment is accurately evaluated.
