SD-800C thermal evaporation coating instrument Introduction: SD-800C thermal evaporation coater is a process in which the substrate or workpiece to be coated is placed in a vacuum chamber, and the coating material is heated to evaporate and vaporize to deposit on the substrate or workpiece surface and form a film or coating. Equipped with high qualitative leap vacuum pump Applicable products: 1. Electron beam sensitive samples It mainly includes biological samples, plastic samples, etc. The electron beam in SEM has high energy. During the interaction with the sample, it transfers part of the energy to the sample in the form of heat. If the sample is sensitive to electron beam, this interaction will destroy part or even the whole sample structure. In this case, the surface coating prepared with a non electron beam sensitive material can act as a protective layer to prevent such damage; 2. Nonconductive sample Because the sample is non-conductive, its surface has an "electron trap", and the accumulation of electrons on this surface is called "charging". In order to eliminate the charging effect, the sample surface can be coated with a metal conductive layer, which acts as a conductive channel to transfer charged electrons away from the material surface to eliminate the charging effect. Sputtered materials increase the signal-to-noise ratio during the formation of scanning electron microscopy, thus obtaining better imaging quality. 3. New materials Observation of conductive characteristics of experimental electrode made of non-conductive materials Technical parameters: Matching pump: two liter leap pump Evaporation target: carbon rod Evaporation current: maximum current 100A, working current 0-80A Limit vacuum: 4 * 10-2mbar Size of sample bin: 160 in diameter and 120 mm in height Sample table size: sample table size diameter 150mm Working voltage: 220V, 50HZ
