In vacuum evaporation coating processes for SAW (surface acoustic wave) filters, evaporation crucibles—including PBN organic EL crucibles and graphite crucibles—are critical components of the evaporation source. They are used to hold evaporation materials and enable stable evaporation in a high-temperature vacuum environment, allowing vaporized molecules to deposit uniformly on the substrate surface and form the…Continue reading How to Select Electron-Beam Evaporation Crucibles: Analysis of Two Composite Structure Options
