While paint, powder coating, electroplating and other common finishing techniques have their places, in some cases only a vacuum will do. Coatings that are deposited through the use of vacuum technology can be far thinner and more regular than those that are applied at atmospheric pressure. In addition, the absence of any possible contaminants in a high vacuum can also mean that such coatings will be virtually free of any degrading additions. In many cases where coatings of the greatest precision, purity, and evenness are required, then, a Vacuum System in Boston MA will be involved.
Typically, the parts and pieces of equipment that are given such attention are used in applications like chip making and biochemical research, where even slight imperfections or amounts of contamination could have grave consequences. In general, then, the presence of such a Vacuum System in Boston MA will be more likely in technologically advanced industries, as opposed to those of more traditional kinds.
The process of depositing a coating in a vacuum is actually quite simple, however. Only a relative few substances are appropriate for this application, with the key factors being that they must behave in an orderly, predictable way in the presence of a vacuum, while still being susceptible to vaporization.
For example, such a vacuum system might be used to deposit regular, thin layers of metallic conductors or special superconducting materials on electronic parts, with those areas that are to remain uncoated simply being masked off beforehand. It might also be used to add pristine, optically pure coatings to lenses meant for research astronomers, biological laboratories, or other demanding users.
Most often, though, coatings that are applied in this way serve a simple, protective purpose. In these cases, any of a range of suitable polymers might be used, as can special coatings based on oxides and other metallic materials. Companies that specialize in adjusting and repairing the equipment used for these purposes, like Yeagle Technology Inc, in fact, might be called upon to adjust a given vacuum deposition machine to make it better able to apply a particular coating for a certain job.
