  • Vacuum evaporation coating

    Vacuum evaporation coating is a technology to obtain film by heating and evaporating a substance on the surface of substrate material under vacuum condition. The evaporated material is called evaporation material. Evaporation coating was first proposed by M.Faraday in 1857. After more than 100 ye...

  • What is a mass Flowmeter and what is a mass flow controller for the PVD vacuum coating machine?

    Mass Flowmeter, or MASS FLOW METER (abbreviated as MFM), is an instrument for accurately measuring gas flow. Its measurement value is not misaligned due to the fluctuation of temperature or pressure and does not require temperature and pressure compensation.   The mass flow controller, Mass fl...

  • What are the measuring methods of film thickness

    Generally, it can be divided into two types: in-situ measurement and off-site measurement. It is widely used in physical vapor deposition, such as microbalance, optical measurement and resistance measurement. The off-position measurement means that after the film is finished, the exercise of th...

  • What is physical evaporation?

    What is physical evaporation? Describe the steps in briefly as following: Physical evaporation is to heat the substance to volatilize and then deposit its vapor on a predetermined substrate. Because the evaporation source must be heated and volatilized and under condition of vacuum, it is so cal...
