Ultra-pure water equipment in the electronics industry is a semiconductor, integrated circuit chip and package, liquid crystal display, high-precision circuit board, optoelectronic devices, various electronic devices, microelectronics industry, large-scale, ultra-large-scale integrated circuits require a large amount of pure water High-purity water, ultra-pure water cleaning semi-finished products, finished products. At present, China's Ministry of Electronics Industry divides electronic-grade water quality technology into five industry grades, namely 18MΩ.cm, 15MΩ.cm, 10MΩ.cm, 2MΩ.cm, 0.5MΩ.cm To distinguish between different water quality.
Ultra-pure water equipment in the electronics industry usually consists of a multi-media filter, activated carbon filter, sodium ion softener, precision filter, etc. Pretreatment system, RO reverse osmosis host system, ion exchange mixed bed (EDI electric desalination system) system And so on constitute the main equipment system. The original water tank, the intermediate water tank, the RO pure water tank, and the ultrapure water tank are all equipped with a liquid level control system, high and low pressure water pumps are equipped with high and low pressure protection devices, online water quality control and control instruments, and electrical PLC programmable controllers are used. It is unattended, and at the same time, the method of recommendation and customer requirements is adopted in the process selection, so that the equipment has higher cost performance and equipment reliability compared with other similar products.
