Uses Of Vacuum Chambers And Pumps

 

A vacuum chamber is a rigid enclosure from which air and other gases are removed by a vacuum pump. The vacuum, or low pressure zone, is created to allow technicians to conduct tests on substances or devices that are required to function in a vacuum. Chambers made of aluminum allow one to control the magnetic field inside from outside the vacuum. Conversely, chambers made of mu-metal prevent external fields from entering the vacuum.

Vacuum chambers are necessary to impede the contamination of samples in varied range of applications in spectroscopy and for film depositions. These ultra high vacuum applications are frequently utilized in semi-conductor manufacturing processes, because even the slightest degree of contamination can be disastrous in this industry. As referenced previously, vacuum chambers produce an environment that is conducive to testing devices that must operate in the vacuum that exists in outer space. Many vacuum chambers are constructed of aluminum, because aluminum, unlike other metals, is not magnetic.

Vacuum chambers are frequently constructed with multiple ports, covered with flanges, to allow instruments or windows to be installed in the walls of the chamber. For processes that only need low to medium levels of vacuum, rubber o-ring seals are utilized. In applications where very high vacuum levels are used, the flanges are made out of hardened steel which are sealed onto copper gaskets.

A type of vacuum chamber frequently used in the field of spacecraft engineering is a thermal vacuum chamber,, which provides a thermal environment representing what a spacecraft would experience in space. These applications also utilize very advanced   vacuum pumps

Vacuum chambers are frequently used when mixing resins and silicone rubbers. A vacuum chamber is needed when manufacturing resins and silicone rubber to insure that the mold is free of air bubbles. In order to prevent air bubbles, material are placed in a vacuum chamber while they set. The substrate upon which the vacuum is applied is mixed according to the manufacturers specifications. Because the material placed in the vacuum will expand to four times its original volume,the mixing container must be large enough to hold a volume of four times the amount of the original material that is being vacuumed to allow for the expansion. If additional volume is not provided, there will not be enough space available to allow the process to reach completion. The container in which the material is held is put into a vacuum chamber and the vacuum is applied when the vacuum pump is turned on. Subsequent to the vacuum attaining 982 mbar, the substrate will commence rising. . When the material falls it will plateau and not rise any more. The vacuuming is continued for another three minutes to make certain all of the air has been removed from the material. After this interval is attained, the vacuum is terminated and the pressure is allowed to equalize with the ambient pressure. At this point the vacuum chamber is opened and the substrate is removed and put into a mold.

Vacuum chambers utilized in the semi-conductor industry involve an exceedingly complex process. Due the very high levels of air purity required to avoid contamination of semi-conductor devices, these devices must be processed in ultra pure vacuums. With the progression of silicon based semi-conductor devices, the need for ultra high vacuum levels have increased to eliminate the possibility of any type of substrate contamination. For this reason, the most advanced ultra high vacuum chambers and pumps are used in space research and semi-conductor manufacturing. For semi-conductor manufacturing applications, impurities of even several molecules can destroy a substrated.
