standard ambient condition：The temperature is 20℃, the relative humidity is 65%, and the atmospheric pressure is101325Pa=1013.25mbar=760Torr。PVD Coating Systems suppliers standard reference conditions for gases：The temperature is 0℃ and the pressure is101325Pa. p pressure：When a gas molecule passes through a hypothetical plane, the momentum change rate along the normal direction of the plane is divided by the plane area or the normal component of the force acting on the surface of the contai... read more
sputtering deposition Basic Principles A solid surface is bombarded with energetic particles (usually positive ions accelerated by an electric field). Sputtering of atoms and molecules on solid surface after exchanging kinetic energy with incident energetic particles is called sputtering. Sputtered atoms (or clusters) have a certain amount of energy. They can be re-deposited and condensed on the surface of solid substrates to form thin films, called sputtering coatings.China Plasma Coating Machi... read more
Vacuum evaporation plating Basic Principles Vacuum evaporation coating is a method of heating the raw materials to form thin films in evaporation container in vacuum chamber to make atoms or molecules escape from the surface and form vapor flow to the surface of solid (called substrate or substrate) to condense and form solid films. The reasons for stricter requirements for vacuum evaporation, especially for vacuum environment, are as follows: Prevent reactions due to air molecules and evaporati... read more
Common vacuum leak detection methods High Frequency Spark Leak Detection This method is only applicable toChina Multi-arc ion coating machine Supplier glass vacuum system. Firstly, the system is vacuum pumped. The spark end of the high frequency spark leak detector moves along the glass surface, and the sparks concentrate in bunches to form the instant leak position at the bright spot. read more
Vacuum meter leak detection method The readings of some vacuum gauges are related to the types of gases, such as thermocouples and ionization vacuum gauges. Choosing appropriate gas or liquid as leakage material, these China Plasma Coating Machine suppliersvacuum gauges become detectors. Generally, there are vacuum gauges on the coating machine, which are very convenient to use and also a commonly used method of leak detection. Leakage indicators used in thermocouples include carbon dioxide, but... read more
