Embodiment

[0041] In this embodiment, a real-time temperature monitoring system for integrated circuit testing equipment, such as figure 1 As shown, it includes a host terminal 1 and a test terminal 2. The test terminal includes several temperature detection units 4 and temperature analysis units 3. The temperature detection units are respectively connected to the temperature analysis units, and the temperature analysis units are connected to the host terminal.

[0042]The temperature detection unit is used to detect the internal temperature of the integrated circuit testing equipment. There are multiple temperature detection units. Resistor R2, thermistor R3 and thermistor R4, thermistor R1, thermistor R2, thermistor R3, and thermistor R4 are respectively connected to the temperature analysis unit. The thermistor adopts three-wire PT100, which has more accurate and sensitive detection, fast thermal response and longer service life.

[0043] The temperature analysis unit is used to read...

Abstract

The invention relates to a real-time temperature monitoring system and method for an integrated circuit testing device, thereby solving problems that the stability and precision of the testing deviceare affected by the too high temperature to cause the test offset and thus the serious quality is caused. The system comprises a host terminal and a testing terminal. The testing terminal includes a plurality of temperature detecting units and a temperature analyzing unit; the temperature detecting units are connected to the temperature analyzing unit respectively; and the temperature analyzing unit is connected to the host terminal. The host terminal reads temperature data in real time; when the temperature value is higher than an early warning threshold, alarming is performed; and when the temperature value is higher than a detection stop threshold, alarming is performed and current testing is stopped. According to the invention, the internal temperature of the integrated circuit test equipment can be monitored; alarming is performed when the temperature is too high and testing can be stopped in a forced manner, so that problems that the test stability of the testing device is reduced and the testing precision offset is caused because the heat in the testing device is not dissipated timely and the internal temperature of the testing device is too high are solved.

Description

technical field [0001] The invention relates to the technical field of test instruments, in particular to a real-time temperature monitoring system and method for integrated circuit test equipment. Background technique [0002] At present, various industries pay more and more attention to the manufacturing, testing, storage and other links of products, such as medicinal materials, food, semiconductors, etc. In order to control the quality of each link of the product, it is necessary to strictly control the temperature. Therefore, the implemented temperature monitoring system maintains strict Temperature data has become an industry norm [0003] In the field of integrated circuit testing, temperature monitoring and control play a very important role. Excessively high temperatures will seriously affect the temperature characteristics of electronic devices, which in turn will affect the stability and accuracy of test equipment, resulting in test deviations and serious consequen...
