The application of semiconductor discrete device reliability testing equipment
2024-09-19
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).

3. Value Delivered by Yudian Temperature Controllers to Customers
Semiconductor testing equipment imposes high demands on temperature controllers. Due to chip price increases and supply shortages of foreign-made temperature controllers, the customer’s initial selections underperformed. After multiple attempts, the customer turned to Yudian. Following a comprehensive selection process, the AI-516 model was chosen for testing, delivering satisfactory results. Yudian further committed to no price increases and stable lead times. Yudian’s products have proven reliable in the semiconductor industry, helping customers enhance production efficiency, improve product quality, and ensure process stability.
4. Customer Feedback on Yudian
"Yudian’s APID self-tuning adaptive technology has significantly reduced our debugging time. Their controllers demonstrate excellent performance, rapid after-sales response, and stable supply periods. We hold a strong positive impression of the Yudian brand and plan to continue using their products long-term."
