Particle Effects on Products

  • Alvin Lieberman


Although many mechanical, optical, and electrical products that are presently being manufactured do not require cleanroom facilities, the need is increasing. The number and type of precise mechanical devices whose operation is degraded if particles are present to interfere with the rate and/or extent of movement increase almost daily. These devices include electronic memory systems, machine tool controls, fluid flow control systems, and even inexpensive ballpoint pens. Two examples of areas where increasing contamination control requirements appear are entertainment and transportation. Musical reproduction systems based on long-playing records or cassette tapes can be produced with only reasonable care to avoid gross contamination. However, high-quality digital audio tape and compact disk systems must be kept much cleaner for optimum performance. Automobile manufacturing is carried out mainly in normal factory areas. However, paint facilities must be kept very clean because the ingression of atmospheric debris can damage the appearance and life of modern glossy painted surfaces. Many vehicle transmissions that may have to operate without needing new fluids replacement for many months are now built in clean areas. This occurs particularly in large, off-road hydraulic machines and in control systems. The precision positioning of components used in these machines means that the hydraulic fluids and their control assemblies must be very clean.
