AI Technical Summary

Problems solved by technology

[0003] Existing resistance heat resistance detection devices used in high-temperature areas of electronic equipment usually place the resistance to be tested in a detection box when testing, and pass high-temperature gas into the detection box to make the resistance in a high-temperature environment , and put the resistor in the detection circuit by introducing the circuit, and judge the heat resistance performance of the resistor by detecting the indicators of the resistor in the high temperature environment. However, when the electronic equipment used in the high temperature area is actually used, there is a high temperature environment. Immediately shut down the fast cooling zone, and restart after cooling for a certain period of time, there is an alternating situation of high and low ambient temperature, and the alternating switching of high and low temperature environments has a great impact on the service life of the resistor. Carrying out continuous performance testing, it is impossible to effectively complete the heat resistance performance testing in a small alternating environment, and the actual testing effect is not good

[0004] In addition, the existing resistance heat resistance detection device used in the high temperature area of ​​electronic equipment usually puts the resistance to be tested in the detection box during use, and is electrically connected to the circuit. When measuring the resistance, the surface of the resistance to be measured is blocked by the access circuit equipment. When the hot air is actually introduced, the hot air in the test box cannot achieve a uniform temperature rise of the resistance to be measured during the flow process, because the surface of the actual resistance installation position is blocked. The area of ​​the resistance is different, and the absolute performance of the resistance under the condition of unaffected conditions should be detected during the test. However, in the initial heating stage of the current detection, the heating uniformity of the surface of the resistance to be tested is poor, and the detection data accuracy in the initial temperature rise situation is low. The actual detection effect is not good
