Cleanroom Classifications:Introduction for Microelectronics Cleanroom
A clean room means a room in which the quantity of particles floating in the air and, when necessary, the temperature, humidity, and pressure, can be controlled, the main objective of the dust in a given room is determined according to the requirements of the products to be handled in the room.
