The electronics industry has extremely high purity requirements for ultrapure water, as even small impurities can have a negative impact on the manufacturing and performance of electronic components. The purity of electronic ultrapure water is as high as 18.2 M Ω* cm, and its standards include the following aspects:
Electrical resistivity or conductivity requirements: The electrical resistivity of electronic ultrapure water is usually within the range of 18.2 megaohms/cm (or higher) or the conductivity is within the range of 0.055 microsiemens/cm (or lower) to ensure extremely high purity of water.
Microbial restriction: Water is required to be free of any bacteria, viruses, or other microorganisms to ensure its high purity.
Particle restriction: It is required that the water does not contain any small particles to ensure that it is not damaged during the production process.
Chemical composition restrictions: There are strict limitations on any water-soluble chemical substances, especially harmful substances such as metal ions that can affect electronic objects.
PH control: Electronic ultrapure water needs to remain neutral or very close to neutral, typically between 6.5 and 7.5.
Electronic grade ultrapure water has a crucial impact on the quality and performance of microelectronic components, therefore its quality and purity must be strictly controlled during the production process. Producing electronic grade ultrapure water that meets international standards can improve the production process and product quality of electronic components, laying a solid foundation for the development of the electronics industry.
