Electronic clean room is currently an indispensable and important facility in semiconductor, precision manufacturing, liquid crystal manufacturing, optical manufacturing, circuit board manufacturing and other industries. Through in-depth research on the production environment of LCD electronic clean room and accumulation of engineering experience, we clearly understand the key to environmental control in LCD production process. Some electronic clean room at the end of the process are installed and their cleanliness level is generally ISO 6, ISO 7 or ISO 8. The installation of electronic clean room for backlight screen is mainly for stamping workshops, assembly and other electronic clean room for such products and their cleanliness level is generally ISO 8 or ISO 9. In recent years, due to the innovation and development of technology, the demand for high precision and miniaturization of products has become more urgent. Electronic clean room generally include clean production areas, clean auxiliary rooms (including personnel clean rooms, material clean rooms and some living rooms, etc.), air shower, management areas (including office, duty, management and rest, etc.) and equipment area (including cleanroom AHU rooms, electrical rooms, high-purity water and high-purity gas rooms, and heating and cooling equipment rooms).
