This technical report is about the project plan of a Wet Station during the period of intern of Ding Cheng International Co., Ltd. The work in the project is to assist in the collection of related information such as hardware equipment, electrical control and software of this Wet Station, and to write a manual for the operation of the Wet Station.
The equipment improving is based on the combination of two different system models. In terms of hardware, the piping of each acid bath unit is redesigned, and other equipment-related parts are replaced. The addition of equipment components to the machine is a functional design of the protection mechanism such as sensors, quick drain pump, and fast refill water valves in the acid bath unit. In order to replace the bath plate, the chemical resistance of the plate was tested. In terms of software, the software technology part of the computer control is very difficult to rewrite. In addition to integrating the control instructions of the machine, it also redesigned the control interface of the operating system and increased the Chemical Mode Select system''s function of rapid acid exchange. These are convenient and quick control process steps for the operator.
About the chemical resistance test of new and old plates is based on considerations of material replacement for the acid bath unit and plate suppliers. Experimental plates were placed in an acidic environment and closed system conditions, and the plates were observed for changes in surface and weight after controlling for different experimental times. The experimental results showed that the old and new plate surface appear the phenomenon of aging and the color was darkened. However, there were no signs of destructive corrosion, embrittlement, or cracking on the surface, and there is no obvious difference in weight change. The results of this experiment can provide a reference for customers and vendors as replacement plates.
