How clean do I need the cleanroom to be?
The cleanroom classification needed depends on specifications for operations to be conducted within. Research in your specific field will probably provide a specification or at least a general guideline.
Key Elements of Contamination Control
We will look at several areas of concern to get a better idea of the overall picture of contamination control. These are the things that need to be considered when providing an effective contamination control program.
Microelectronics Cleanroom
Semiconductor and electronics industry are essential in this era as the consumer electronics are becoming the basic necessity for people around the world. Consumer electronics are used every day, commonly in communications, office productivity and also for entertainment purpose. In an electronics manufacturing plant, cleanrooms are fundamental to the production line so that the goods fabricated are of high reliability.
Most of the semiconductor, microelectronics, electronics, automotive industry need cleanrooms that follow ISO 14644-1 or its predecessor, FED-STD-209E cleanroom standards.

GMP Compliant Cleanroom
GMP or Good Manufacturing Practice guidelines provide guidance for manufacturing, testing and quality assurance as the respective manufacturer must meet the minimum requirements in the guidelines to assure that the products are of high quality and do not pose any risk or harm to the consumer or public.
Pharmaceutical, healthcare, chemical and food industry are some of the examples of industries that need to follow GMP guidelines. The cleanroom should be compliant with GMP EU Classification.
