Application of ultra pure water particle counter in electronic semiconductors
2022-07-05 07:39:00 【particle counter 】
The application of water in the production process of electronic semiconductor industry is highly required , Therefore, most enterprises will choose ultra pure water equipment with high cost performance . Ultra pure water equipment in electronic semiconductor industry is usually made up of multi-media filters , Activated carbon filter , Sodium ion softener 、 The pre-treatment system is composed of precision filters 、RO Reverse osmosis host system 、 Ion exchange mixed bed (EDI Electric desalting system ) System, etc. constitute the main equipment system . Raw water tank 、 Intermediate water tank 、RO Pure water tank 、 Ultra pure water tanks are equipped with liquid level control systems 、 High and low pressure water pumps are equipped with high and low pressure pressure protection devices 、 Online water quality detection and control instrument 、 Electrical use PLC Programmable controller , Truly unattended , At the same time, the method of unifying recommendation and customer requirements is adopted in process material selection , Compare this equipment with other similar products , It has higher cost performance and equipment reliability .
Plody U-200 Application of ultra pure water particle counter in electronic semiconductors , The Ministry of electronic industry of China divides electronic water quality technology into five industry levels . The national standard for high purity water is :GB1146.1-89 to GB1146.11-89 , The electronic grade moisture of high-purity water is divided into five grades :Ⅰ level 、Ⅱ level 、Ⅲ level 、Ⅳ Level and Ⅴ level , This standard is a reference ASTM Electronic standard . The resistances correspond to :18MΩ.cm、15MΩ.cm、10MΩ.cm、2MΩ.cm、0.5MΩ.cm, To distinguish different water quality .
The main basis of various indicators specified in the water quality standard of ultra pure water is :1、 Requirements of microelectronic technology for water quality ;2、 The level of water making process ; 3、 Current situation of detection technology .
Plody U-200 Ultra pure water particle counter can detect particles in ultra pure water , Minimum detectable 0.03 micron .
Ultra pure water plays an increasingly important role in the production of electronic components , Ultra pure water quality has become a problem that affects the quality of electronic components 、 One of the important factors of production yield and production cost , Water quality requirements are also getting higher and higher . In the production process of electronic components , Ultra pure water is mainly used as cleaning water and to prepare various solutions 、 size , Different electronic components have slightly different uses of pure water and requirements for water quality in the production process . Therefore, the production water of the electronic industry cannot be separated from ultra pure water equipment , This is also the reason why the electronic industry uses ultra pure water equipment .
