Yudian Multi-Channel Temperature Controllers Comprehensively Enhance Equipment Control Quality

Laser aging test equipment typically operates within a temperature range of 40–150°C. Since chips are highly sensitive to temperature variations, even minor fluctuations can significantly impact test results. Yudian’s customized temperature control solutions effectively address these production challenges for equipment manufacturers.

High-Precision Temperature Control Improves Defective Product Screening Efficiency

Equipped with Yudian’s high-precision APID self-tuning adaptive algorithm, the AI-7548D71 temperature controller minimizes temperature fluctuations caused by external disturbances, ensuring a stable testing environment. This enables equipment manufacturers to efficiently identify defective chips resulting from extreme temperature variations, such as solder aging, delamination, bond wire detachment, and cracking.

Multi-Channel Independent Control for Flexible Functionality

Aging test equipment must simultaneously test multiple chips, requiring individual temperature control for each test fixture to observe chip behavior under extreme conditions. The Yudian AI-7548D71 controller features multi-channel independent control, ensuring precise temperature conditions for each chip and further enhancing testing accuracy and reliability.

Compact Design Saves Installation Space

To ensure testing accuracy, large sample sizes necessitate numerous temperature control points. However, aging test equipment often faces space constraints due to high integration. The Yudian AI-7548D71 controller addresses this with a sleek design (width: 22.5mm) and 4 integrated control channels per unit, optimizing space utilization without compromising performance.
