Problems solved by technology

[0005] In the existing technology, there is a lack of detection methods for the life of radar equipment, and it is impossible to provide the failure law of radar equipment under different temperature and humidity, and different electrical stress shock conditions, so it is impossible to analyze the average service life of radar equipment in different environments. The staff also cannot know whether the radar equipment has reached the average service life, so preventive maintenance cannot be carried out effectively, which affects the performance of its combat effectiveness, increases maintenance costs and time, and seriously weakens our country's national defense force

Embodiment

[0041] Example A method to obtain the life of radar through the accelerated degradation test of temperature, humidity and electrical stress

[0042] A method for obtaining radar life through temperature, humidity and electrical stress accelerated degradation tests provided in this embodiment is as follows: figure 1 shown, including the following steps:

[0043] (1) Selection of test samples.

[0044] In this embodiment, a certain type of radar equipped with a 20Kz signal generator is used as the test object. All test samples are obtained through imitation circuit boards. Design according to the design layout of the original circuit board to ensure that the imitation board is completely consistent with the original board in terms of function, appearance, and design layout. The details are as follows: figure 2 As shown, it includes: three operational amplifiers and four triodes, wherein the non-inverting input terminal of the first operational amplifier U1 is used to conn...

Abstract

The invention relates to a method for obtaining the radar service life through temperature and humidity and electric stress accelerated degradation tests. The method comprises the steps: (1), selecting a test sample; (2), testing the test sample, namely, testing the selected test sample; (3), processing the test sample after testing, namely, after the test is completed, selecting various items of data of the test sample through a signal and detecting; and (4), obtaining the average service life of a radar, namely, judging the service life of a circuit board of the radar in different environments through various items of data measured in the step (3). The advantages of simple structure, low cost and high precision are achieved. The method is suitable for detecting the service life of the circuit boards of various radars.

Description

technical field [0001] The invention relates to a method for obtaining the service life of a radar circuit board, in particular to a method for obtaining the service life of a radar through accelerated degradation tests of temperature, humidity and electrical stress. technical background [0002] In recent years, with the continuous development of science and technology, various countries have paid more and more attention to the national defense armed forces as the national protection shield. And because many of the current national defense equipment use radar equipment as the main equipment of the weapon equipment system, the performance of the radar equipment directly determines the strength of the national defense force. [0003] Due to the particularity of the application field of radar equipment, national defense requires radar equipment to meet the requirements of use and achieve the accuracy of use. However, the current environment is complex, and the circuit board of...
