Product Description
Electronics Modular Cleanroom Project
This electronics modular cleanroom project was designed for a precision electronics manufacturer in Lodz, Poland. The client needed a clean production area inside an existing factory building for electronics assembly, component testing, inspection, repair work, and small-batch production.
Instead of rebuilding the entire workshop, the client chose a room-in-room modular cleanroom solution. This allowed them to create a controlled clean area inside the factory with less construction work, shorter installation time, and better flexibility for future production changes.
STJh Cleanroom provided a complete modular cleanroom system including prefabricated wall panels, aluminum frame structure, transparent observation windows, modular ceiling, cleanroom doors, FFU and HEPA filtration, ESD-safe workstations, controlled entry, pass box transfer, LED lighting, environmental monitoring, and installation support.

Project Background
The client already had an operating factory, but the existing workshop could not provide enough cleanliness control for precision electronics assembly and inspection. A traditional fixed cleanroom would have required more construction work, higher cost, and longer disruption to the factory.
The modular cleanroom was selected because it could be installed directly inside the existing production building. The room-in-room structure created a dedicated clean zone without changing the entire factory layout. This solution helped the client start clean production faster while keeping the surrounding workshop available for normal operation.
The cleanroom was planned around real electronics production needs, including ESD-safe workstations, testing benches, inspection areas, material carts, operator movement, maintenance access, and future expansion. The transparent wall design also made the clean area easier to supervise from outside.
Client Pain Points
No dedicated clean area: The existing factory space could not provide enough particle control for precision electronics assembly.
Limited construction time: The client needed a cleanroom solution that could be installed quickly without long production shutdowns.
Budget control: A full fixed cleanroom renovation would have increased the project cost and construction complexity.
Future layout changes: The client needed a cleanroom that could be expanded or adjusted when workstation quantity changed.
ESD risk: Sensitive electronic components required grounded benches, antistatic flooring, and safer handling areas.
Uncontrolled material movement: Components, tools, and fixtures needed cleaner transfer between clean and non-clean areas.
Limited environmental visibility: Temperature, humidity, and pressure conditions needed to be monitored during daily operation.
Modular Cleanroom Solution
STJh Cleanroom designed a 240㎡ room-in-room modular cleanroom inside the client’s existing factory building. The solution used prefabricated cleanroom panels, aluminum profile frames, transparent observation windows, cleanroom doors, modular ceiling, FFU air supply, HEPA filtration, ESD-safe workstations, pass box transfer, and environmental monitoring.
The modular system reduced site construction work and allowed the cleanroom to be installed faster than a conventional fixed cleanroom. The design also gave the client flexibility to add more workstations, adjust the layout, or expand the clean area in the future.
Key Cleanroom Systems
1. Modular Frame & Panel System
The cleanroom uses prefabricated panels and an aluminum frame structure to create a clean production zone inside the existing factory. The system is suitable for fast installation, future relocation, and layout adjustment.
Prefabricated modular cleanroom panels
Aluminum frame structure
Transparent observation windows
Expandable and reconfigurable layout
2. FFU & HEPA Filtration System
Ceiling-mounted FFU units with HEPA filters provide clean air supply for the electronics assembly area. The airflow system helps reduce airborne particles around workstations, components, and testing equipment.
FFU clean air supply
HEPA particle filtration
Stable airflow over workstations
Reduced dust risk for sensitive electronics
3. ESD-Safe Workstations
The cleanroom includes ESD-safe workstations, grounded benches, antistatic flooring, and grounding points to protect sensitive electronic components from electrostatic discharge.
ESD-safe assembly benches
Antistatic flooring
Grounding points for workstations
Reduced hidden component damage risk
4. Controlled Entry System
The compact entry area helps control personnel movement before entering the clean production zone. This reduces contamination brought in by operators and supports better cleanroom discipline.
Controlled cleanroom access
Compact gowning area
Cleaner personnel flow
Reduced people-borne contamination
5. Material Transfer System
The pass box and transfer workflow allow tools, components, test fixtures, and packaged materials to move between clean and non-clean areas with less door opening.
Pass box for cleaner transfer
Reduced unnecessary door opening
Cleaner movement of tools and components
Improved workflow efficiency
6. Environmental Monitoring
The monitoring system gives operators visibility of temperature, humidity, pressure, and cleanroom status. This helps the client manage daily operation and respond faster when room conditions change.
Temperature monitoring
Humidity monitoring
Pressure status visibility
Better control of daily cleanroom operation
7. Flexible Expansion Design
The modular cleanroom was designed with future growth in mind. Additional panels, FFU units, workstations, or clean zones can be added when production demand increases.
Expandable modular structure
Reserved space for additional workstations
Easy layout adjustment
Suitable for changing production needs
8. Efficient Electronics Production Layout
The internal layout was planned around assembly benches, inspection stations, testing equipment, material carts, and operator movement. This helps keep the cleanroom compact while supporting practical daily production.
Clear production flow
Optimized workstation layout
Better use of limited factory space
Suitable for fast clean production deployment
Problems Solved for the Client

Project Result
After completion, the client received a 240㎡ electronics modular cleanroom for assembly, testing, inspection, and repair work. The cleanroom created a controlled production zone inside the existing factory without requiring a full workshop rebuild.
The project helped the client reduce construction time, improve particle control, strengthen ESD protection, organize workstation layout, and prepare for future cleanroom expansion. For electronics manufacturers, this modular solution is suitable when they need a clean production area quickly and want to avoid the cost and disruption of a large fixed cleanroom project.
