Anti-static Softwall Cleanrooms

Deiiang Anti-static Softwall Cleanrooms can be designed for ISO 5–ISO 8 cleanliness classifications in accordance with ISO 14644-1. ESD-control measures can be specified and verified using applicable IEC 61340-5-1 and ANSI/ESD S20.20 principles. Final compliance depends on the approved design, operating conditions, validation scope and project-specific regulatory requirements.

ESD risks are controlled through anti-static PVC curtains, conductive or static-dissipative flooring, grounded metal frames, equipotential bonding and dedicated grounding points. Where required, ionizers can be installed at critical workstations. Typical project targets include surface resistance of 10⁶–10⁹ Ω, static decay time of no more than 2 seconds and ion balance within ±35 V, subject to the approved user requirement specification.

As-built testing can include airborne particle counting in accordance with ISO 14644-1, HEPA filter integrity testing, airflow velocity and air-change measurements, smoke-flow visualization, differential-pressure verification and temperature/RH monitoring. ESD testing can include curtain and flooring resistance, resistance-to-ground, grounding continuity, static decay and ionizer balance. Tests are performed with calibrated instruments, and project-specific reports can be supplied.

Deiiang Anti-static Softwall Cleanrooms can be configured for ISO Class 5, ISO Class 6, ISO Class 7 or ISO Class 8 applications. Fan filter units fitted with H13 or H14 HEPA filters are selected according to the required cleanliness level, room dimensions, process heat load and occupancy. Airflow quantity, FFU coverage and filter arrangement are engineered for each application rather than based on a single standard configuration.

Anti-static Softwall Cleanrooms are commonly used for semiconductor handling, PCB assembly, electronic component testing, display and LED production, lithium-battery processes, precision optics, aerospace components, medical electronics and research laboratories. The appropriate cleanliness and ESD-control levels are determined by component sensitivity, process risks and the customer’s quality requirements.

A typical design may maintain a temperature of 20–24°C, relative humidity of 45–60% and positive pressure of approximately 10–20 Pa. Actual setpoints depend on the process, local climate, personnel load and host HVAC system. Humidity control is especially important because very dry conditions can increase electrostatic charging, while excessive humidity may affect products and equipment.

Anti-static curtains and flooring should be cleaned with compatible, non-insulating products under a documented maintenance procedure. Grounding connections, curtain resistance, floor resistance-to-ground and ionizer performance should be inspected and tested at risk-based intervals. Damaged curtain strips, loose bonding conductors and saturated pre-filters should be repaired or replaced promptly, with all maintenance and retest results recorded.

Yes. Depending on the agreed project scope, Deiiang can provide approved drawings, equipment specifications, material data sheets, HEPA filter certificates, particle-count reports, airflow and pressure records, ESD test results, instrument calibration certificates and operation and maintenance manuals. Documentation packages can also include installation records, deviation and corrective-action records, and final handover summaries to support internal or third-party audits.

Yes. The modular structure can be customized for room dimensions, cleanliness class, FFU quantity, curtain configuration, ESD flooring, lighting, ionization, access control and monitoring requirements. Subject to site conditions and engineering review, the cleanroom can also be relocated, expanded or reconfigured as production requirements change. Requalification is recommended after changes that may affect airflow, cleanliness or ESD performance.

Deiiang provides project-specific cleanroom engineering that integrates particle control, airflow management and ESD protection. Each system can be supported by documented design criteria, traceable components, installation guidance, calibrated performance testing and maintenance recommendations. Customers should review the proposed technical specifications and validation scope against their process risks, applicable standards and regulatory obligations before approval.
