Electronics Cleanrooms are used in the production of Printed Circuit Boards, Fibre Optics, and Assembly of Components
A cleanroom is a controlled environment where products are manufactured. It is a room in which the concentration of airborne particles is controlled to specific limits. Eliminating sub-micron airborne contamination is really a process of control. People, process, facilities and equipment generate these contaminants. They must be continually removed from the air. The level to which these particles need to be removed depends upon the standards required. ISO 14644 is the document that establishes standard classes of air cleanliness for airborne particulate levels in cleanrooms and clean zones. Strict rules and procedures are followed to prevent contamination of the product.
The only way to control contamination is to control the total environment. Air flow rates and direction, pressurization, temperature, humidity and specialized filtration all need to be tightly controlled. And the sources of these particles need to controlled or eliminated whenever possible. There is more to a clean room than air filters. Cleanrooms are planned and manufactured using strict protocol and methods.
