Requirements and control of moisture content in compressed air in electronics factories
Electronics manufacturing industry background
The electronics manufacturing industry has extremely strict requirements for humidity control of compressed air, especially in key processes such as SMT mounting, PCB cleaning, and chip packaging. According to ISO 8573-1:2010, the moisture content of compressed air for electronics factories needs to be controlled within the range of-40℃ to-70℃ (PDP, pressure dew point). Even a trace amount of water remains, it may cause solder joint corrosion, component failure, and even cause a short circuit on the circuit board. The oil-free screw air compressor has passed the German Tüv “0” oil-free certification and has become the core equipment to ensure the quality of electronic products.
Why electronics factories need to pay attention to compressed air moisture content
- product quality assurance
Moisture can cause solder oxidation, affect the strength of solder joints, and then cause electronic component failure. - equipment reliability
Moisture entering pneumatic components will cause rust and seizure, and the equipment failure rate will increase by 20%-30%. - Certification compliance
Comply with SEMI F5 clean room gas standard and support enterprises to pass ISO 9001 quality management system certification. - energy consumption optimization
The intelligent dehumidification system improves energy efficiency by 15%-20%, complying with the ISO 50001 energy management system standard.
Shanghai Granklin Group’s oil-free screw air compressor adopts oil-free compression technology that meets international standards to meet the 7×24-hour continuous operation needs of the electronics factory.
Selection of core parameters for compressed air in electronics factories
According to ISO 8573-1:2010 Class 0 and SEMI standards, the following parameters need to be verified:
- dew point control
-70℃ (PDP) ±3℃ (requires environmental management system certification support). - oil content
<0.01ppm (requires German Tüv “0” oil-free certification). - dust content
≤0.01μm (verification by product quality and safety certification certificate is required). - noise control
≤75dB(A)(requires occupational health and safety management system certification).
The oil-free screw air compressor adopts an intelligent constant temperature control module combined with EU CE certification to ensure operation reliability in a high temperature and high humidity environment.
Potential risks of not controlling the moisture content of compressed air
If the humidity of compressed air is not effectively controlled, it may cause:
- Product defective rate rises
Moisture causes oxidation of solder joints, and the product defect rate increases by 5%-10%. - Frequent equipment failures
Rust of pneumatic components resulted in production suspension, with annual losses exceeding 5 million yuan. - Certification fails
The FDA compliance review found excessive humidity and cancelled export qualifications. - Energy consumption soars
The energy consumption of the post-treatment system (adsorption tower + filter) increased by 25%.
By comparing the ISO 8573-1:2010 standard with traditional equipment parameters (dew point ≥-40℃), the necessity of efficient dehumidification technology can be clarified.
Economic benefits of using oil-free screw air compressors
- Reduce energy costs
Permanent magnet frequency conversion technology saves annual electricity bills by more than 180,000 yuan (132kW model). - Reduce quality losses
The product pass rate has increased by 5%-8%, and the annual scrapping cost has been reduced by 300,000 yuan. - extend equipment life
The oil-free design reduces bearing wear rates by 80%, and extends maintenance cycles to 24 months. - Carbon tax optimization
In line with the EU Carbon Border Regulation Mechanism (CBAM), export costs are reduced by 8%-12%.
Comparison of oil-free screw air compressor versus traditional equipment in electronics factories
| parameters | Oil-free screw air compressor | Traditional oil lubrication equipment |
|---|---|---|
| Dew point control accuracy | ±2℃ (intelligent closed-loop control) | ±10℃ (adsorbent efficiency decay) |
| oil content | <0.01ppm (Tüv certification) | ≥0.1ppm (requires three-level filtration) |
| microbial control | ≤1CFU/m³ (online monitoring) | ≥100CFU/m³ (high risk of contamination) |
| Average annual maintenance cost | 80,000 – 120,000 yuan (no consumables design) | 300,000 – 500,000 yuan (oil-containing filter replacement) |
| equipment life | 15-20 Year (fully enclosed structure) | 6-10 Year (caused by oil pollution corrosion) |
| compliance of | Passed 8 certifications including CE/Tüv/SEMI | Only meets basic security certification |
summary
Choosing oil-free screw air compressors for electronics factories is the core decision to ensure product quality and production efficiency. By strictly adhering to the ISO 8573-1:2010 standard and German Tüv “0” certification, such equipment eliminates the risk of moisture and oil pollution and improves international market access. Leading manufacturers such as Shanghai Granklin Group use innovative technologies to promote industrial upgrading and provide global electronics companies with clean compressed air solutions that meet Industry 4.0 requirements.
