Thermal Evaporation Systems 101

You may have heard about thermal evaporation systems, but assumed from the name that it was something involving climate change or some other environmental issue.

In actuality, thermal evaporation is an integral part of physical vapor deposition, or PVD. The latter is one of the processes used when a thin coating is required in an industrial capacity. Thermal evaporation is one of the most familiar types of PVD, largely because it is also one of the least complex.

A resistant heat source evaporates a chosen material in order to create the coating mentioned above. That coating is then put into a high vacuum chamber and subjected to heat, creating a vapor. Thermal energy causes this vapor to then pass through the vacuum chamber. In the process, it coats the substrate adding a layer of protection in the process.

Thermal evaporation is an effective process for several reasons, not the least of which is its ability to deposit metals and nonmetals. That makes it an especially desirable choice for electrical contacts.

PVD differs from Chemical Vapor Deposition (CVD) in that the latter takes place at a higher pressure. This eliminates the need for a vacuum pressure pump, which reduces costs, as long as the system in place is not also needing a gas management infrastructure. The deposition also does not require line of sight in CVD and that makes it invaluable for coating surfaces that are irregular in nature. Low pressure chemical vapor deposition systems are in widespread laboratory use.
