Anti-static cleanroom for the electronics industry
I. Core Technical Parameters
1. Cleanliness Indicators
●Optional Classes: ISO 7 (Static ≥0.5μm particles ≤352,000/m³; Dynamic ≤3,520,000/m³), ISO 8 (Static ≥0.5μm particles ≤3,520,000/m³; Dynamic ≤35,200,000/m³)
●Filtration System: Pre-filter + Medium-efficiency filter + H14 grade HEPA high-efficiency filter, filtration efficiency for 0.3μm particles ≥99.99%, ULPA ultra-high efficiency filter optional.
●Airflow Organization: Top-mounted/side-mounted FFU fan filter units are optional. Top-mounted units achieve vertical laminar flow coverage, side-mounted units are suitable for small workshops, and horizontal laminar flow has no airflow interference. Air exchange rate: 30-60 times/hour (ISO 7), 15-30 times/hour (ISO 8)
2. Anti-static Core Indicators
●Surface resistivity: Floors, walls, and ceilings are uniformly controlled within 2.5×10⁴～1×10⁹Ω, meeting the standards for electrostatic dissipative materials.
●Grounding system: The entire system uses a conductive copper foil grounding network with a grounding resistance <4Ω. Equipped with a grounding alarm device for real-time warnings in case of abnormalities.
●Static voltage control: Equipped with a pulsed ion fan, neutralization speed ≤0.3s, stable surface static voltage ≤100V within the cleanroom, eliminating dead zones for static electricity accumulation.
●Anti-static accessories: Standard configuration includes anti-static workbenches, anti-static wrist strap interfaces, and anti-static flooring, forming a closed-loop anti-static system throughout.
3. Environmental control parameters
Temperature control: 20±2℃ (accuracy ±0.5℃); Humidity control: 45%~65%RH (accuracy ±5%RH); A low-humidity environment (≤30%RH) can be customized for lithium battery-specific models; maintaining a positive pressure of 5-10Pa to prevent external contaminated air infiltration; equipped with intelligent temperature, humidity, and pressure differential sensors for real-time data monitoring.
II. Core Design Highlights
1. End-to-End Anti-static Structure Design
The walls and ceiling are constructed using conductive color steel panels, with conductive adhesive used to seal the gaps between the panels, eliminating gaps that can accumulate static electricity. The floor uses anti-static epoxy self-leveling compound or PVC roll material, paired with a conductive grounding copper mesh, ensuring rapid and uniform discharge of static electricity and eliminating the risk of localized excessive static. Doors and windows are equipped with anti-static tempered glass, and door frames are fitted with conductive sealing strips, achieving integrated anti-static protection for the entire cleanroom, suitable for scenarios with stringent static electricity control, such as automotive electronics and semiconductors.
2. Modular and Flexible Adaptability to Production Lines
Built on a lightweight aluminum alloy frame, all components are prefabricated in the factory, allowing for rapid on-site assembly and installation in just 3-7 days. No damage to the existing workshop structure is required. Custom sizes and layouts can be tailored to different processes such as PCB surface mount technology, chip packaging, and lithium battery winding. Supports future expansion, relocation, and reconstruction, perfectly adapting to the needs of electronics companies expanding production or adjusting production lines, reducing construction costs by more than 50% compared to traditional cleanrooms.
3. Intelligent Monitoring and Compliance Assurance
Standard configuration includes an online anti-static monitor, particle counter, and intelligent alarm system. Core data (static electricity value, cleanliness, temperature and humidity, grounding resistance) are uploaded to the management platform in real time, supporting remote viewing, historical data traceability, and anomaly alerts. It complies with international standards such as German Industry 4.0 and EU CE, helping customers pass industry compliance testing. All materials are electronics industry-specific, with no leaching, corrosion resistance, and easy cleaning and disinfection, avoiding secondary contamination.
4. Targeted Process Adaptation
Customized for different processes in the electronics industry: PCB production models are suitable for the entire process of surface mount technology (SMT), soldering, and testing, equipped with an anti-static soldering workbench and ion gun; semiconductor models enhance cleanliness and static electricity neutralization efficiency to prevent chip breakdown; lithium battery models optimize for low-humidity environments and explosion-proof design, balancing static electricity protection and safe production.
III. Typical Application Scenarios
●PCB Circuit Boards: Full process including surface mount technology (SMT), insertion, soldering, drilling, testing, and packaging.
●Automotive Electronics: Production and assembly of automotive sensors, automotive chips, and wiring harness connectors.
●Semiconductors/Microelectronics: Packaging and testing of microchips, diodes, transistors, and sensors.
●Lithium-ion Batteries: Electrode slitting, stacking, winding, cell packaging, and module assembly.
●Other Electronic Components: Production of small sensors, electronic modules, and precision instrument parts.
