Technical Field

[0001] The utility model relates to the technical field of integrated circuits, in particular to a hybrid integrated circuit aging monitoring system. Background Art

[0002] At present, integrated circuits have been widely used in aviation, military, industry and other industries, and their reliability has become a major consideration for the widespread application of devices. As one of the most important reliability tests, the aging test is a method of allowing products to work under stress for a period of time to stabilize their characteristics. The stress used in the aging test needs to meet the premise of not destroying the electrical performance of the product, and can eliminate those defective products that will fail early due to potential adverse factors in raw materials, design, production, etc. from a batch of products; in this way, qualified products can be selected to ensure the reliability of the products. Through the aging test, devices with inherent defects caused by process defects can be effectively eliminated to ensure that the failure rate level of the device meets user needs. If the aging test is not carried out, defective devices will experience initial fatal failure or early life failure under the conditions of use. Especially for industries with particularly high reliability requirements such as the military industry and the aerospace industry, the aging test is a common method, and in the reliability test, the aging test is the longest and most complex test.

[0003] There are various test systems and methods for performing aging tests on various integrated circuits. Different test systems and methods may have poor compatibility, be cumbersome and time-consuming, have temperature control problems, and the shell temperature cannot be accurately controlled. Therefore, there is an urgent need to propose a hybrid integrated circuit aging monitoring system that can more conveniently control the electrical aging process and make the company more standardized in the aging of hybrid integrated circuits. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hybrid integrated circuit aging monitoring system, comprising: an aging monitoring unit, the aging monitoring unit is provided with a first communication port, a first power supply interface, and a first network interface; an aging heating platform, the aging heating platform is provided with a plurality of aging platforms, as well as a second communication port, a second power supply interface and a second network interface, each of the aging platforms is respectively provided with a temperature control unit and an execution unit; an emergency alarm unit, the emergency alarm unit is provided with a third communication port and a control port; the first communication port and the second communication port communicate with the third communication port respectively; the first network interface and the second network interface communicate via a local area network.

[0006] Preferably, the emergency alarm unit is composed of a UPS emergency power supply, a heating platform protection unit, and an audible and visual alarm.

[0007] Preferably, the UPS emergency power supply is provided with a pair of power output ports and a signal receiving port, the power output port is electrically connected to the first power supply interface and the second power supply interface respectively, and the signal receiving port communicates with the control port.

[0008] Preferably, it also includes a power supply group, which is provided with a power input terminal, a plurality of independent output terminals, and a fourth communication port; the power input terminal is electrically connected to the power output port of the UPS emergency power supply, and each of the power output ports is electrically connected to the corresponding aging table.

[0009] Preferably, the temperature control unit includes a temperature controller and a K-type thermocouple electrically connected to the temperature controller.

[0010] Preferably, the execution unit comprises a PTC heater, and the PTC heater is electrically connected to the corresponding power output port through an AC solid-state relay.

[0011] The beneficial effects of the utility model are as follows: the aging monitoring unit is the main body of control, running the aging platform monitoring software and temperature inspection instrument, reading the data of each aging platform in the aging heating platform in real time, and centrally displaying the operating status of each aging platform, storing the operating status data of the aging platform in real time, and sending out an alarm sound through the sound and light alarm system in case of abnormality, and the local area network is the medium for message transmission between the aging heating platform and the aging monitoring unit, so that in the large-scale aging process, it can ensure the rapid transmission of monitoring information, solve the temperature control problem in the aging process of hybrid integrated circuits, realize the precise control of shell temperature, and more conveniently control the electrical aging process, so that the company is more standardized in the aging of hybrid integrated circuits. The emergency alarm unit is controlled by the aging monitoring unit, so that the city power supplies power to the aging monitoring unit and the aging heating platform after passing through the UPS emergency power supply. The thermostat is preferably Omron E5CZ, which integrates all functions in the aging temperature control process, so it only needs to be equipped with a K-type thermocouple and a PTC heater to use it. This design makes the development speed fast, the cost low, and the function strong. The most important thing is that the product has been verified by the market to be stable and reliable, which is particularly important for industrial control products. Among them, the K-type thermocouple is preferably the ETA K-type thermocouple temperature measuring line with a plug, which is easy to disassemble and assemble, with a maximum temperature measurement of 480℃, and a temperature measurement accuracy of SLE level (1.1℃ or 0.4%). The PTC heater has a small resistance and a large power when the temperature is low; it has a large resistance and a small power when the temperature is high; therefore, it can be matched with a thermostat to achieve a fast and stable temperature control effect. Due to the sealed structure, the insulation and safety are increased, and the temperature consistency is better. In addition, since the PTC heater is powered by 220V AC, an AC solid-state relay is required for control. The solid-state relay is preferably ASR03-325DA from Aix, which is relatively large in size and the current of 25A is far greater than the use requirements. Since the AC solid-state relay has high power, no contacts, and zero-crossing type, it has little interference with the power grid and is relatively safe to use, because the damage of a small solid-state relay will cause serious consequences of output short circuit. In addition, the PTC heater is equipped with an axial flow fan, which is mainly used to avoid overshoot caused by unstable temperature control process and to cool down the device. Another function is to accelerate the cooling of the device when the module is removed. BRIEF DESCRIPTION OF THE DRAWINGS
