The manufacturing process of flat-panel liquid crystal display products involves a variety of complex processes and fields. Wet equipment occupies more than 30% of the processes. Among them, cleaning, development, etching, and peeling are all strictly required, such as LCD panels and semiconductors. The wet process of components or printed circuit boards (PCBs) usually uses a mixed acid solution of acetic acid, nitric acid or hydrofluoric acid for etching treatment, so a large amount of waste liquid containing acetic acid, nitric acid or hydrofluoric acid is generated during the process. The cleanliness of the solution will directly affect the final performance and effect of the product. Therefore, filtration is an extremely important link. We analyze the requirements of each link for different working conditions and develop effective filtration solutions. To provide you with high quality products.
