1.Application Equipment: Photovoltaic diffusion equipment

2.Product Model Used: AI-8x9 Series

3.Process Overview:

Temperature is a critical parameter in photovoltaic diffusion processes, significantly influencing oxidation rate, oxide layer quality, and overall process efficiency and cost. Precise temperature control during oxidation is essential to ensure uniformity and high-quality oxide layers. Excessively high temperatures may accelerate oxidation rates, causing defects and stress that degrade mechanical and electrical properties of the material. Conversely, low temperatures slow oxidation rates, extending production cycles and increasing energy consumption. Optimizing temperature control is thus crucial for enhancing process performance and reducing costs.

4.Challenges Addressed for Customers:

In oxidation processes, high-temperature environments and stringent control precision often result in temperature fluctuations and complex debugging. Yudian’s cascade temperature controller, featuring a proprietary automatic calibration adaptive cascade control algorithm, simplifies debugging significantly. It achieves a temperature control error of ±0.5°C, reduces fluctuations during constant-temperature processes, and minimizes defects caused by temperature variations. Even when process parameters are modified, no repeated adjustments to temperature control settings are required.

5.Customer Feedback:

Yudian provides 24/7 technical support, resolving issues remotely or dispatching engineers on-site within the shortest timeframe. During end-customer equipment debugging, both the equipment and process departments have highly praised Yudian instruments. Users highlight the simplicity of debugging, stable temperature control, and significant reduction in workload for end customers.
