The growth of AI, data centers, and advanced electronics is driving demand for components and technologies that require high-precision manufacturing—from electronic devices to photonics, which uses light to transmit and receive data. These manufacturing processes depend on controlled environments, making cleanrooms an essential part of production infrastructure.
What Does a Cleanroom Control, and Why Does Every Project Require a Tailored Approach?
A cleanroom controls airborne particle levels, along with temperature, humidity, pressure, and airflow, according to the requirements of the manufacturing process. It does not necessarily have to be sterile. Pharmaceutical and medical manufacturing may require control of microorganisms and contamination, while electronics manufacturing places emphasis on particles, temperature, and humidity. Before determining the appropriate cleanliness level, it is essential to understand the product’s sensitivities, the heat and particles generated by equipment, and the intended use of each area. These considerations form the basis for technical requirements suited to actual production needs.
The challenge lies in ensuring that Heating, Ventilation and Air Conditioning (HVAC), air filtration, electrical systems, utility systems, control systems, architectural works, and cleanroom materials function in coordination. Changes in airflow direction may affect room pressure, while heat generated by production equipment affects cooling demand. Design must therefore account for system interdependencies from the outset, including equipment layout, service routing, and maintenance access, so that engineering requirements can be implemented effectively during construction and operation.
As a Multi-Disciplinary EPC Contractor, Italthai Engineering brings together engineering teams across disciplines to plan and manage work within a single project, ensuring that all systems support the manufacturing process and each client’s specific requirements.
What Role Does a Cleanroom Play in Advanced Electronics Manufacturing?
In advanced electronics manufacturing, dust and small particles can cause product defects, while temperature and humidity affect process consistency. ISO 14644-1 classifies cleanroom cleanliness levels according to airborne particle concentrations. The appropriate class must be selected to suit each area and stage of production.
Italthai Engineering is currently working on an advanced electronics manufacturing project that includes ISO Class 6, 7, and 8 cleanroom areas, each accommodating different manufacturing requirements. The project requires coordination across multiple engineering disciplines under stringent safety, operating, and system precision requirements. Air systems, electrical systems, utilities, and building works must be aligned with the requirements of each classified area.
The company has also delivered a cleanroom for a face mask manufacturing facility. Its experience further includes pharmaceutical, food, and nutrition-related projects, where it prepared spaces and related engineering systems to accommodate subsequent cleanroom development. These projects demonstrate the importance of tailoring cleanroom requirements to each manufacturing process and its applicable standards.
Why Are Testing & Commissioning Critical to Cleanroom Performance?
A cleanroom project does not end once construction and system installation are complete. It must undergo Testing & Commissioning to verify that the systems can maintain the required conditions, including airborne particle levels, temperature, humidity, pressure, airflow direction, and the performance of filtration and control systems.
Cleanroom performance must be demonstrated through measurable, verifiable results. This provides confidence that the space and its engineering systems are ready to support the manufacturing process in accordance with project requirements.
Key Parameters Measured During Cleanroom Testing & Commissioning
The Cleanroom Testing & Commissioning process verifies and measures essential parameters to ensure compliance with design standards, including:
- Airborne Particle Control and particle concentration levels
- Temperature and relative humidity levels
- Room pressure differentials and airflow direction
- Performance of Cleanroom HVAC Systems and air filtration efficiency
Providing verifiable testing results ensures that the cleanroom facility and engineering systems are fully prepared to support high-precision manufacturing safely and reliably.
An Effective Cleanroom Goes Beyond Compliance to Deliver Optimum Value
Setting cleanliness levels beyond what the process requires can increase capital investment, energy consumption, and maintenance costs. An effective cleanroom must therefore achieve the right balance between manufacturing quality, safety, investment, and suitability for long-term operation.
