ESD Cleanroom Design
Integrate particle control and ESD protection for electronics manufacturing, precision assembly, and testing. Customize the system to your cleanliness targets, equipment layout, and process requirements.
Integrated ESD Protection
- Static-Control Materials: ESD flooring and dissipative surfaces help reduce charge accumulation. Resistance requirements are defined by the site-specific ESD control plan.
- Grounding and Personnel: Equipotential bonding, wrist straps, footwear systems, and entry testing support controlled charge dissipation.
- Optional Ionization: Ionizers help neutralize charges on insulators and objects that cannot be grounded directly.
Hardwall Construction
Modular wall panels, low-shedding finishes, and sealed joints support flexible layouts, routine cleaning, and stable room pressure.
Environmental Control
- Cleanliness and Filtration: Design options target ISO 5–8 with H13 or H14 HEPA filtration, subject to airflow design and on-site classification.
- Pressure and Climate: Airflow, pressure differentials, temperature, and humidity are tailored to process needs. Humidity control supplements—not replaces—ESD protection.
Testing and Documentation
Agreed testing may include particle counts, airflow, pressure, HEPA integrity, flooring resistance, grounding continuity, and ionizer performance. Test records and maintenance documentation support acceptance and audits.
Industry Solutions
Semiconductor Manufacturing
Semiconductor processes involve sensitive components that can be damaged by airborne particles and electrostatic discharge.
- Key Risks: Particle contamination, static discharge, wafer or chip handling defects.
- Recommended Design: ISO 5–7 cleanroom options, H13/H14 HEPA filtration, ESD flooring, grounding network, and optional ionization.
Electronics Assembly
Electronics assembly areas require controlled static dissipation during PCB, sensor, module, and component handling.
- Key Risks: ESD damage, dust contamination, unstable grounding, and personnel-related charge transfer.
- Recommended Design: Static-control flooring, dissipative work surfaces, wrist strap and footwear grounding, entry testing, and controlled humidity.
Precision Assembly
Precision assembly processes require a stable environment to protect small, high-value, and contamination-sensitive parts.
- Key Risks: Micro-particle contamination, static attraction of dust, assembly defects, and product yield loss.
- Recommended Design: Hardwall enclosure, sealed joints, controlled airflow, positive pressure, ESD-safe materials, and routine monitoring.
Testing Laboratories
Testing areas for electronic devices and precision products benefit from controlled cleanliness, grounding, and stable environmental conditions.
- Key Risks: Static interference, inconsistent test results, contamination during inspection, and equipment sensitivity.
- Recommended Design: Grounded work zones, ESD-safe furniture, environmental monitoring, HEPA filtration, and documented maintenance procedures.
Medical Electronics
Medical electronic products often require clean assembly conditions and reliable ESD control to support product safety and quality consistency.
- Key Risks: Contamination, static damage to electronic modules, and quality control nonconformance.
- Recommended Design: ISO-class cleanroom design, HEPA filtration, static-control surfaces, grounding verification, and documented acceptance testing.
Testing & Validation
ESD-Safe Hardwall Cleanroom Testing & Validation
Challenge: Precision electronics, semiconductor, micro-component and new energy battery manufacturing environments require dual compliance with cleanroom cleanliness and ESD electrostatic protection standards. Conventional cleanroom testing only detects airborne particle levels, ignoring critical ESD risks including static accumulation, sudden electrostatic discharge, unstable grounding and unqualified anti-static surface performance. Poor ESD control easily causes micro-chip breakdown, component damage and product short circuits, resulting in low production yield. Unstandardized testing procedures also lead to ISO certification failures, customer audit non-compliance, incomplete qualification records and even batch product quality issues and production shutdowns.
Solution: Our comprehensive ESD-Safe Hardwall Cleanroom validation service integrates environmental cleanliness testing, professional ESD performance verification and standardized factory qualification, fully compliant with ISO 14644 and ANSI/ESD S20.20 industry standards. Our full-range test items cover airborne particle concentration counting, HEPA/ULPA filter integrity and leakage detection, air change rate and airflow uniformity testing, pressure cascade stability verification, as well as temperature and humidity accuracy calibration. Meanwhile, we complete core ESD tests including surface resistance detection, grounding system continuity verification, static decay time measurement, ionizer balance inspection and ESD protective material compatibility testing.
Full-Standard Qualification Process: We adopt a complete DQ, IQ, OQ and PQ four-stage qualification system to achieve full-life-cycle compliance verification for ESD cleanrooms. DQ verifies the design scheme matches production processes and industry risk standards; IQ confirms the standardized installation of anti-static panels, grounding devices and filtration systems; OQ tests stable parameter operation under no-load conditions to ensure qualified cleanliness and zero static hazards; PQ implements long-term monitoring under actual production loads to verify continuous stable operation of the cleanroom environment.
Customer Core Value & Compliance Guarantee: All testing is completed with fully calibrated instruments, with real-time recorded traceable data and official validation reports. We provide complete qualification documents and test records to support enterprise internal quality filing, third-party certification and global customer factory audits. Customized routine monitoring, regular retesting and professional ESD maintenance solutions are also available to sustain long-term cleanroom and ESD compliance, reduce product defect rates, eliminate production safety risks and meet strict quality requirements for high-precision manufacturing.
FAQ
Deiiang ESD-Safe Hardwall Cleanrooms can be designed and validated in accordance with applicable ISO 14644 cleanroom requirements and customer ESD-control procedures. Depending on the application, the cleanroom may incorporate conductive or dissipative flooring, grounded wall panels, workstations, equipment bonding points and personnel grounding provisions. Final compliance scope is confirmed according to the project specification, process risk assessment and local regulations.
Typical ESD-control features include static-dissipative or conductive flooring, a dedicated equipotential grounding network, grounded hardwall panels and ceiling components, ESD-safe doors and work surfaces, personnel grounding points and optional wrist-strap or footwear testers. Ionization equipment can also be integrated where sensitive products or insulating materials require additional charge neutralization.
Handover testing can include particle counts in accordance with ISO 14644-1, HEPA filter integrity testing using PAO/DOP methods, air velocity and airflow-volume measurements, differential-pressure verification, temperature and relative-humidity monitoring, smoke visualization tests and instrument calibration records. ESD-related checks may include floor resistance, resistance-to-ground, grounding continuity and ionizer performance verification when applicable.
Yes. The HVAC system can be configured to maintain specified temperature, relative-humidity and room-pressure conditions. Appropriate humidity control helps reduce static-charge generation, while the final setpoints should be determined by the product sensitivity, process requirements, operator comfort and applicable ESD-control program.
Project documentation can include as-built drawings, equipment layouts, electrical and grounding diagrams, operation and maintenance manuals, material data sheets, HEPA filter test reports, particle-count reports, balancing records, calibration certificates and ESD test records. Documentation packages can be tailored to support customer qualification, internal quality review and audit requirements.
Deiiang ESD-Safe Hardwall Cleanrooms combine rigid, durable cleanroom construction with integrated contamination and electrostatic-discharge control. The solution can be customized for electronics, semiconductor-related processes, medical devices, precision assembly and other static-sensitive applications, with design support, installation coordination, testing documentation and ongoing maintenance or spare-parts assistance available according to project needs.
