Big Blue Blog - History of Cleanrooms

1900s

Aseptic techniques and sterilisation processes (used in modern day cleanrooms) are used within hospital operating theatres.

1950s

 

The HEPA filter was fundamental to industrial cleanrooms, supplying clean air to manufacturing areas, with low airborne contamination levels for the manufacture of components like missile gyroscopes. 

The early types of cleanroom were non-unidirectional airflow (or turbulent airflow) cleanrooms.

1960s

 

The space race accelerated the development of controlled production environments into the modern cleanroom concept.

Rocket engines were found to have failed when liquid oxygen release valves jammed due to contamination by microscopic dust particles. As a solution, unidirectional airflow cleanrooms were developed.

Contamination control provided an airborne cleanliness level over 1000 times cleaner than that of the earlier non-unidirectional airflow cleanrooms and continues to provide a major method of contamination control to this day.

The global development of microelectronics and decreasing circuit geometry led to large cleanroom manufacturing sites with emphasis on the control of sub-micron size particulate, electrostatic and chemical contaminants. 

1970s

 

Developments i health-care products led to the global use of very closely controlled and regulated Pharmaceutical and Biomedical cleanroom manufacturing facilities.

1990s

 

There are major changes to cleanroom standards and considerable technological changes to cleanrooms with the advent of isolation technology. 

2000s

 

Cleanrooms are used throughout the modern world for the manufacture of products, such as electronics and semiconductor devices, medicines, medical devices, paint and surface finishes, optical devices, food and drinks.

Throughout cleanroom development various National and International Standards, Guidelines, Test Methods and Recommended Practices have been introduced and subsequently updated, and continue to evolve.
