Application Industry: New Material Production and Processing

Product Model Used: AI-869

Process Overview:
The Yudian AI-869 is utilized in vacuum furnace equipment for processes such as synthesis, sintering, and annealing of electronic materials. The performance and stability of electronic components are directly influenced by temperature due to their material properties and internal structures being highly sensitive to temperature changes.

On-Site Application Details:
Cascade control is employed to reduce temperature fluctuations, ensuring stable quality and shortening the product development cycle.

Problems Solved for Customers:
Due to the complexities introduced by the vacuum environment and external heating lag, precise temperature control can be challenging. Yudian's cascade temperature control method achieves high precision and supports multiple communication protocols and interfaces, seamlessly integrating with other on-site control equipment.

Value Delivered to Customers:
Primarily reflected in cost reduction and efficiency improvement. Previously, customers used two separate instruments to achieve cascade temperature control. After adopting Yudian's cascade controller, the operation complexity was significantly reduced, making it almost as simple as controlling a single loop. Aside from setting the main PID parameters, adjusting only the Cc parameter during cascade tuning is needed to determine the auxiliary control action within the cascade system. This allows for easy comparison of different cascade control effects.

Customer Feedback:
Using a single instrument for cascade control not only reduces production costs but also improves on-site debugging efficiency. It perfectly replaces temperature control products from Japanese brands like Shimaden.
