  • The cleaning of the PVD vacuum coating product

    Why cleaning?    Before the vacuum process, the workpiece or material should be cleaned to remove the pollutants from their surface; it’s also very necessary of vacuum parts to do surface cleaning,because the gas and steam sources caused by the pollutants will not only make the vacuum system unab...

  • Basic plasma knowledge introduction

    One、What is the plasma? Plasma is the fourth state of matter except solid, liquid and gas. It is mainly dissociated by gas under the action of high electromagnetic field to form a highly active substance consisting of electrons (with negative charge), positive ions (with positive charge), free ...

  • 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...

  • What are the characteristics of good films? What are the influencing factors?

    It is said that under normal conditions, its application function will not fail. To achieve this, the film must generally have strong adhesion, low internal stress, little pinhole density, strong mechanical performance, uniform film thickness, and sufficient resistance to chemical erosion. The...
