Cleanrooms and laboratories generally have standards for contamination control and lab safety. These may include protective clothing for workers, HEPA filtration systems, and ultraviolet equipment.
Four critical areas of potential contamination:
Particles. The number of particles released from a substrate is traditionally the most important criterion for cleanliness. Low particle counts on products brought into the cleanroom are desirable to reduce contamination of critical surfaces as well as the general cleanroom environment.
Fibers. Low fiber counts are desirable. Many processes that can withstand a level of small particle contamination are much more sensitive to large particles and fibers.
Nonvolatile Residue (NVR). Non-particulate organic compounds transferred from gloves, wipes, swabs, apparel, tape, etc. The nonvolatile residue can be detrimental in cleanroom manufacturing.
Ions. Ionic contamination can cause failure by changing the electrical properties of a material through the corrosion of metallized layers.
Items to help prevent contamination in a cleanroom environment:
Cleanroom Wipes, Swabs, and Mops for cleaning and cleaning validation.
Adhesives Floor Mats remove dirt from shoes and cart wheels to prevent contamination of a controlled environment.
Cleanroom Vacuums feature HEPA filters to capture 99.97% of particles down to 0.3 microns.
Particle Counters for measuring particulate size and concentration in the air.
Cleanroom Furniture including stainless steel tables, cleanroom chairs, and stools.
Cleanroom Stationery including paper, notebooks, notepads, and labels.
Cleanroom Apparel including coveralls, gloves, shoe covers, and more.
Static Control Products, including wrist straps, grounders, ionized air guns, testers, and sprays
