Production today is one of the primary parts for every production houses of every sector. Even more, the electric component production in whole is a meticulous and integral part for an electric component manufacturer. While dealing with intricate and brittle components, strong measures should be thoroughly kept in prior to before the production. One of the vital understanding in manufacturing of these electric components is the place or area of manufacturing plant where appropriate conditions are met with the utmost maintenance of standardization. For such needs to be fulfilled, the clean room plays an integral part in controlling the environment of the laboratory and plants where such electronic components are manufactured.

Now, what is a clean room and what does it do?

A clean room is an artificially-controlled environment which limits the presence of sub-micron particles such as dust, airborne microbes, aerosol, chemical vapours and many other components present in the air and modifies the environment as per to the operators need. By limiting the pollutants, the clean room furthermore contains and takes out the existing contamination. These clean rooms are labelled and categorized into several categories. The evaluation of the clean room is done in terms of the level of sub-micron particles present inside the clean room per cubic foot of air; i.e. the lower the ratio the cleaner the room is said to be.

Now, we will move unto how to create a clean room for your facility.

To begin with, you must know the purpose of creating a clean room so that you can create suitable kind of clean room with respect to your production, which means, if you are into storing goods which are less reactive to pollutants then you may not want the level of cleanliness which is required by the companies that manufacture electrical components such as circuits. The right kind of clean room according to your needs will definitely help you in making of the cost-effective clean room.

Basically, we have divided the whole process of making a clean room facility in several steps.

Evaluation of layout for people and material flow

It is really beneficial to know how and where you are going to build your clean room so an initial blueprint is required. This blueprint will contain personal access doors, pathways, critical place, location of the airlock, vents and everything which are required for an efficient clean room.

Determining space cleanliness classification

This is the part where the application of the clean room measures with that of the ISO standards of clean rooms. There are various classifications based on the no of sub-micron particles per cubic foot in a clean room. As mentioned earlier, be specific enough to know what level of ISO classification clean room you will be needing before making one.

Determining Space Pressurization

A properly made clean room always has a maintained positive air space pressure. By the meaning of positive air space pressure, the cleanrooms are maintained with more filtered air than the surrounding space outside the cleanroom. Usually, the facilities such as delicate electrical components making require higher space pressurization. However, higher the space pressurization the harder it is to maintain the clean room which thus, results in high cost.

Determining space air exfiltration

A clean room does have a planned space air exfiltration however the unplanned space air escapes through electrical outlets, windows and door frames, wall and floor interfaces, etc. firstly, there is no such thing as 0% leakage in a clean room. However, it is important to keep the clean room sealed. A volume leakage of 1% -2% is defined as a well-sealed cleanroom. So we have to bear in mind that our clean room is well sealed in the making.

Assessment of other remaining variables

Now that the framework along with the well-sealed clean room is made, we move unto the evaluation of several other variables.


Working in a clean room needs proper attire. The plastic bunnies worn by the people inside a clean room will undoubtedly make the body temperature rise. So, it is necessary to maintain a lower space temperature inside a clean room. The temperature range 66-degree Fahrenheit to 70-degree Fahrenheit will provide comfort inside the clean rooms.


The high airflow of clean room results in the development of increased electrostatic charge. These electrostatic charges may come in contact with airborne particles resulting in wearing out the specifications of clean rooms. So, it is necessary to keep the space relative humidity enough to reduce the electrostatic charge.


It is important for a well-built clean room to have a regular laminar flow of exfiltration of contaminants. So a proper check of airflow laminarity is necessary while building a proper clean room.

Conductive flooring

A clean room can sometimes discharge high levels of electrostatic discharges. These discharges can result in accidents so a proper installation of grounded and conductive flooring is to be made to prevent accidents in the cleanroom.

Noise and vibrations

After the evaluations of the major components of a clean room, we must check the noise level and vibration inside the cleanroom. If the airflow components are making intense noise than usual, then it is necessary to replace them so that the intricate process going inside the facility won’t be disturbed by the noise and vibration.

A well-prepared clean room is a place where science meets art. These intricate and properly designed rooms are specimens of human potential in bringing out higher efficiency in production. But when improperly designed, they are not efficient enough to help you with the production. In order to make a well-sufficed cleanroom, we recommend you to consult with an experienced engineer or your contractor who can supervise you from start to end of the whole process. It is also necessary that the regular monitoring of the clean room should be done in order to be operated on a regular basis.
