A room where the particulate levels are controlled to specified levels in each particle size range. Clean rooms are specified in terms of the maximum number of particles of a certain size permitted in a given volume of air. (Federal Standards 209E). The maximums are called "classes". For example, a Class 10,000 clean room can have a maximum of 10,000 particles with an average diameter of .05 microns and larger in each cubic foot of air.
An area in which a high degree of cleanliness is achieved and maintained by controlling the generation and distribution of particulate matter inside the room. Cleanliness is achieved by air filtering and/or dilution systems in a controlled environment.
A room constructed to maintain a controlled atmosphere (humidity, temperature, dust, germ free, etc.).
These are the facilities used to assemble or service hard disks. They are environmentally controlled and dust-free.
a room that is virtually free of dust or bacteria; used in laboratory work and in assembly or repair of precision equipment
a facility with controlled environment to protect sensitive equipment from contamination
a necessity for those customers where contamination is a serious concern
an enclosed space in which airborne particulates, contaminants, and pollutants are kept within strictly controlled limits i
a room where the concentration and the size of particles, the temperature and the humidity of the environment are controlled according to a standard
a specially constructed enclosed area which is environmentally controlled with respect to airborne particulates, temperature, humidity, air pressure, air-flow pattern and lighting
a sterile environment in which a
a work area in which the air quality, temperature and humidity are highly-regulated in order to protect sensitive equipment from contamination, important in the production of silicon chips, microprocessors and other technologies
a work area with controlled temperature and humidity to protect sensitive equipment from contamination
A room in which the concentration of airborne particles is controlled, and which is constructed and used in a manner to minimize the introduction, generation and retention of particles inside the room, and in which other relevant parameters I.e. temperature, humidity, and pressure are controlled as necessary. Meets an ISO Class 8 rate or better.
Applications characterized by the common requirement to minimize outside contamination. These type applications limit the use of lubricants and coolants. Special materials and seal materials are necessary to meet these requirements. Many medical and pharmaceutical applications require clean room features.
A room, with the environmental controls (temperature and humidity) are maintained plus the environment is maintained pure "clean" free of contamination by HEPA filters or some other type of (HEPA) high efficiency small particle removal filters.
The place where semiconductor manufacturers do all their wafer processing. Dust and particles which might fall on the wafers during processing and result in the circuits not working are kept out of the clean room by filtering the air and managing the air flow. Humans are required to wear specially designed clean room bunny suits (overalls) and booties over their street clothes, and must put on gloves and face masks (humans tend to shed skin and hair). Normal paper is not allowed in clean rooms -- only clean room low particulate paper may be taken in.
Semiconductors are constructed within a cleanroom, which is a very precisely controlled (and clean) environment.
A room in which the concentration of airborne particulate matter is controlled through positive pressure. This extremely sterile environment is used for the manufacture of sterile and highly purified products. Back to glossary index
An environment which is controlled to minimize contamination due to particulates and other airborne pollutants. Polymer Science, Inc. has Class 100 coating, converting and packaging production areas.Converting - To change a material either in length, width or overall appearance.
A manufacturing area that contains air specially filtered to remove dust particles.
A room built to prevent the entrance of dust or lint, usually it will also have closely controlled humidity and temperature.
An environmentally controlled, dust-free, assembly or repair facility in which hard drives are assembled or opened for internal servicing.
An environmentally controlled, dust-free facility in which hard drives are assembled or opened for internal inspection or servicing.
A room in which the concentration of airborne particles is controlled to specified limits (Federal Standards 209E). Click for Larger Image
An enclosed, ventilated or air-conditioned area, free of airborne particles where delicate components, such as engines and automatic transmissions, can be assembled with minimal risk of contamination.
A contaminant free environment
An enclosed room employing control over particulate matter in the air with temperature, humidity, and pressure controls
A room in a high risk decontamination facility which is used by workers to change from street clothes into protective work clothing and equipment prior to entering the designated work area.
A manufacturing area where the air is filtered and the temperature, humidity and dust particle size is controlled.
