What is a Clean Booth? Why do electronics factories need it?

What is a Clean Booth?

A Clean Booth (also called a modular clean room) is a flexible cleanroom solution assembled from independent modules. It’s commonly used in areas needing controlled cleanliness without constructing a full permanent cleanroom.

The components of a Clean Booth include:

  • A sturdy aluminum profile or 304 stainless steel frame

  • Transparent PVC plastic film or anti-static fabric for partitions

  • HEPA/ULPA filters to remove up to 99.99% of particles ≥ 0.3 µm

  • FFU (Fan Filter Units) to create unidirectional airflow (laminar flow), maintain positive pressure, and control cleanliness levels

Clean Booths are widely used in industries requiring strict particle control, such as electronics, semiconductors, healthcare, and pharmaceuticals.

Why do electronics factories need Clean Booths?

The electronics industry demands ultra-clean and stable manufacturing environments, especially when working with:

  • Semiconductor components

  • Integrated circuits (ICs)

  • Printed Circuit Boards (PCBs)

  • Touchscreens, sensors, etc.

Clean Booths help control several key factors:

  • Fine dust control: Even a particle ≥ 5 µm can damage microstructures or cause defects

  • Static electricity reduction (ESD): Prevents electrostatic discharge that can destroy sensitive components

  • Stable, clean airflow: Reduces cross-contamination during assembly

  • Flexibility and reusability: Suited for production lines that change over time

Using Clean Booths boosts production efficiency, reduces defect rates, and meets international standards such as ISO 14644, ESD, and GMP in modern electronics manufacturing.

Criteria for choosing an ISO-compliant Clean Booth for electronics factories

To ensure production effectiveness and meet international testing requirements, electronics factories should select Clean Booths that comply with ISO 14644. Important technical criteria include:

Criterion Requirement
Cleanliness class ISO Class 5 to ISO Class 8, depending on production area (IC, SMT, inspection, etc.)
Airflow speed 0.3 – 0.5 m/s to maintain unidirectional flow and prevent cross contamination
Filter efficiency ≥ 99.99% for HEPA/ULPA filters, removing particles ≥ 0.3 µm
Construction materials Aluminum/steel frame, PVC or anti-static fabric partitions, easy to clean
Expandability Modular design for easy disassembly, relocation, or expansion

Details on each:

  • Cleanliness class: Different areas require different ISO classes. For example, ISO 5 for high-end chip fabrication or semiconductors; ISO 7–8 for board assembly and packaging.

  • Stable airflow: Clean Booths should maintain stable airflow between 0.3 – 0.5 m/s to create positive pressure and prevent ingress of contamination.

  • Filter performance: HEPA/ULPA filters must be periodically tested to ensure effective removal of microscopic particles.

  • Static protection (ESD): Walls, floors, and grounding systems must meet ESD standards to protect electronic devices from discharge.

  • Modular flexibility: The Clean Booth should be modular (assembled from parts) for easy reconfiguration and future expansion.

Benefits of using a supplier that meets ISO standards

Choosing a supplier that delivers ISO-compliant Clean Booths provides electronics companies with not only high quality cleanrooms but also optimized operational and cost efficiency. Specific benefits include:

Guarantee of ISO 14644-1 compliance:

  • Design and construction fully align with cleanliness class, airflow, pressure differential, and particle count requirements
  • Meet international audit and certification demands to ensure product quality

Cost-optimized design and installation:

  • Advice on proper configuration for each production area (SMT, packaging, inspection, etc.)
  • Avoid over-specification or under-investment

Shorter installation time:

  • Professional teams ensure fast implementation with minimal disruption
  • Use of prefabricated modular components for on-site installation

Support in validation, calibration, and accreditation:

  • Full test procedures for ISO 14644-1, ESD, airflow, pressure differential
  • Operation manuals and periodic testing schedules
  • Provide documentation such as IQ (Installation Qualification), OQ (Operational Qualification), PQ (Performance Qualification)

These documents are especially important for companies aiming for export or international partners’ quality assessments.
