Vacuum Gauge

In large-scale industrial vacuum systems—vacuum furnaces, PVD coating chambers, freeze-dryers, and metallurgy lines—the rough vacuum stage sets the foundation for every successful process cycle. This is where the system transitions from atmosphere to the 10⁻³ Torr crossover point, where mechanical pumps hand off to high-vacuum pumps. Pressure must be monitored accurately, quickly, and reliably to […]

In thin-film deposition processes such as magnetron sputtering, electron-beam evaporation, and thermal evaporation, coating uniformity across the substrate is the difference between a functional device and scrap. Variations as small as 5 % in thickness can degrade optical performance, reduce semiconductor yield, or compromise adhesion in protective coatings. While substrate rotation, target power, and source-to-substrate

In vacuum metallurgy processes—vacuum arc melting, vacuum induction melting, electron-beam melting, and high-temperature heat treatment—precise pressure control directly determines material purity, microstructure, and final mechanical properties. Oxygen, nitrogen, or hydrogen partial pressures above 10⁻⁴ Torr can cause embrittlement, inclusions, or unwanted phase changes. Yet the operating environment is punishing: chamber temperatures often exceed 1500 °C,
