Description
1771-W Universal I/O
1771-W according to the semiconductor diffusion / oxidation process requirements, that is, both to achieve the entire process control process automation and semiconductor diffusion / oxidation process requirements. The system takes PLC as the core, LCD touch screen as the human-machine interface, and adopts self-developed JC-9 temperature detection module to realize the collection of temperature and so on.
In the semiconductor production process, the accuracy of the diffusion furnace temperature control and its work stability has become a decisive factor in the quality of semiconductor products. However, in the traditional control, the control and management of the diffusion furnace are completed by the instrumentation based on microcontroller
1771-W temperature control precision, production process control ability and automatic operation ability are low and difficult to realize centralized management, which leads to the defects of poor product quality and low production efficiency.
