Turbomolecular Pumps
- martedì 12 ottobre 2021
Turbomolecular pumps are one of the most iconic parts of a vacuum deposition plant. Their appearance evokes the structure of a turbocompressors of the type used in commercial jet aircraft engines (turbofans).
Surface Finish
- martedì 31 agosto 2021
You may have noticed that the finishing of the internal surfaces of the vacuum chambers tends to be more and more accurate as the basic vacuum you want to obtain is more severe. The reason is that the amount of water that must be managed due to the outgassing phenomenon increases with the increase in the surface roughness of the chamber.
O-rings in high vacuum systems
- venerdì 18 giugno 2021
O-rings are fundamental elements of high vacuum systems. They are seals in elastomeric material, with a circular section, intended to be inserted in special seats, and to be compressed during use, acting as a sealing element.
Technical Gases in Vacuum Deposition Processes
- venerdì 23 aprile 2021
Many industrial vacuum deposition processes require an environment with a controlled composition of the environment: a certain amount of high purity technical gases is then continuously fed into the chambers, using controlled flow valves called MFC (Mass Flow Controllers).
Aluminum (and its alloys)
- giovedì 11 febbraio 2021
Aluminum, although not many know it, is a metal with extraordinary properties. It does not exist in nature in the metallic state, but always in the form of compounds, the best known of which is Bauxite, in which it is contained in the form of oxides and hydroxides.
