In the nano-scale chip manufacturing process, even if there is one part in a billion of impurities in the water, it is like dropping a huge rock onto a smooth mirror, which can cause the entire batch of wafers to be scrapped. Therefore, the electronic-grade ultra-pure water system is no longer an auxiliary device; instead, it has become the "heart" of the production line. Baohupu deeply focuses on the needs of the semiconductor industry and has created an electronic-grade ultra-pure water system that strictly follows international standards to safeguard your chip manufacturing.
1. How Pure Is Electronic Grade Ultra-Pure Water? Understanding the ASTM Standards
The ultra-pure water in the electronics industry complies with the ASTM D5127 standard set by the American Society for Materials and Testing. Its requirements for key indicators have reached an extremely high level:
Resistivity (at 25℃): ≥ 18.2 MΩ·cm (theoretical limit value)
Total Organic Carbon (TOC): ≤ 5 ppb (micrograms per liter), and even a requirement of ≤ 2 ppb is set.
Particulate matter (greater than 0.05 μm): ≤ 1 per mL
Microorganisms (bacteria): ≤ 1 CFU/1000 mL
Silicon dioxide: ≤ 2 ppb
The design goal of the Baohupu electronic-grade ultra-pure water system is precisely to consistently produce water that meets and exceeds this standard.
II. Core Technology Guarantee of Baohupu Electronic Grade Ultra-Pure Water System
To ensure the quality of the water output is completely reliable, the Baihupu system integrates a number of cutting-edge technologies:
1. Deep desalination and TOC removal process:
By adopting the "RO + EDI + polished mixed bed" triple insurance method, the resistivity is ensured to remain stable continuously.
At the critical positions of the system, 185nm/254nm dual-wavelength ultraviolet lamps (UV lamps) are installed. These lamps effectively decompose the organic carbon (TOC) in the water, oxidizing it into carbon dioxide and water, and then removing it through the degassing membrane.
2. Strict microbiological control plan:
The system adopts a fully enclosed closed-loop design and uses 0.04μm ultrafiltration (UF) as the final filtration step, effectively trapping bacteria and heat sources.
The pipeline is made of highly smooth PVDF or 316L stainless steel material, and is equipped with a regular sterilization function to prevent the growth of microorganisms and the formation of biofilms.
3. Intelligent Monitoring and Data Traceability:
The system not only monitors resistivity and TOC, but also conducts comprehensive monitoring of temperature, pressure, flow rate, and SDI (pollution index).
All water quality data are recorded in real time and generate reports, meeting the strict requirements of the semiconductor industry for quality traceability and providing data support for process improvement.
