Cleanrooms play an essential role in contamination-sensitive applications such as semiconductor fabrication, pharmaceuticals, optics, medical devices/life sciences, and many more. Cleanrooms control the number of particulates in the air (such as dust, microbes, and aerosols) to avoid compromising cleanroom processes and products made there. Standards for these enclosures are tight, especially for motion systems used in them. But following a few basic techniques lets designers use linear motion devices while maintaining an appropriately clean environment. Cleanrooms are classed according to the number of particles of a specific size per unit volume of space. To control the size of particulates in a cleanroom, designers filter and minimize the introduction of new particulates from personnel, materials, and equipment. Controlling particulate generation can be a challenge, particularly when the cleanroom encloses machinery. Micro-lithography, for example, uses slots of robots and other motion
