1. Introduction：

Semiconductor discrete device reliability testing equipment is specialized equipment designed to evaluate evaluate the reliability and stability of semiconductor discrete devices under various conditions. These devices simulate environmental and electrical stress scenarios that components may encounter during actual operation, conducting a series of tests and monitoring to determine whether the devices can function properly within specified timeframes and under defined conditions. They are primarily categorized into environmental stress testing, electrical stress testing, and other specialized testing equipment.

2. Application of Temperature Control Instruments in Semiconductor Discrete Device Reliability Testing Equipment

The reliability testing equipment produced by Tianjin Hairui Electronic Technology Co., Ltd. is mainly used for testing IGBT modules. As IGBT modules are critical power semiconductor devices, they demand stringent temperature control during testing. The testing principle involves rapidly heating or cooling the device under test (DUT) via electrothermal water-cooled plates, causing the junction temperature (Tc) to rise or drop abruptly in repeated cycles (see Figure 1 for details).
