Electron Beam Evaporation – Definition Electron beam evaporation, or E-beam evaporation, is a type of physical vapor deposition (PVD) technique, which directly heats the evaporation material (usually pellets) by using an electron beam under vacuum, and transports the vaporized material to the substrate to form a film. Electron Beam Evaporation – Working Processes Electron beam evaporation...Continue Reading

The case A well-known industrial glass company—-We attempted to deposit a silver film about one micron thick on the glass substrate using silver evaporation materials by vacuum evaporation. And our existing coating facilities are limited that we can only use electron beam evaporation. We tried Ag / Ti glass in the beginning, but the silver...Continue Reading
