Introduction Physical vapor deposition (PVD) and thin-film coating systems demand precise pressure control across a wide range—from atmosphere during venting and load-lock cycling to high vacuum during sputtering or evaporation. A gauge that cannot deliver stable, repeatable readings in both regimes will cause thickness variations, poor adhesion, or arcing that scrapes entire batches. Engineers and […]

Introduction Most industrial vacuum processes span six decades of pressure—from atmosphere during venting and roughing to high vacuum during deposition, etching, or analysis. A single gauge cannot deliver accurate, continuous readings across this entire range. Thermal-conductivity gauges lose sensitivity below 10−3 Torr; ionization gauges cannot operate reliably near atmosphere. The practical solution is to combine

Introduction In industrial vacuum systems, pressure stability is not a luxury—it is a fundamental requirement for consistent product quality, repeatable process results, and maximum equipment uptime. A fluctuation of even 10 % in chamber pressure can shift deposition rates, alter etch profiles, or introduce defects in semiconductor wafers, thin-film coatings, or vacuum-brazed components.
