The electroplating area in the cleanroom supports cleanroom process production and is an important part of the process production. Its environmental design is of great significance to ensuring product yield and process stability.

[0003] The electroplating process area uses various corrosive media, and the complex piping layout occupies a portion of the indoor space. To save space for piping and allocate the limited indoor space to process layout and production, raised floors are often used. With raised floors, some special pipes can be placed under the floor, optimizing indoor piping space and facilitating wiring and maintenance. Using raised floors in the electroplating process area is a proven and reasonable indoor space utilization solution. However, because corrosive media are used in this environment, the metal components of the raised floor are corroded to varying degrees, affecting floor safety.
