Introduction of several coating methods of vacuum coating machine

2023-04-09

There are many kinds of coating technologies for vacuum coating equipment. Simply put, in a vacuum environment, the film material particles are emitted by evaporation, sputtering, etc., and deposited on metal, glass, ceramics, semiconductors, and plastics. The coating layer required by the customer

Introduction to basic knowledge of vacuum coating equipment

2023-04-09

The vacuum coating machine uses the orthogonal magnetic field in the vacuum state to make the argon ions formed by the electron bombardment of the argon gas and then bombard the target, and the target ions are deposited on the surface of the workpiece to form a film.

The arc power supply is the realization of target evaporation and ionization in the arc ion coating must rely on the arc power supply to provide energy. In the actual coating process, the power supply must be able to automatically detect the arc extinguishing phenomenon and automatically start the arc to ensure the continuity and film quality during the coating process. layer uniformity

When the buyer purchases the vacuum coating machine, the manufacturer Shengchang equipment will generally be equipped with a machine maintenance manual. Both the buyer and the manufacturer attach great importance to the maintenance of the vacuum coating machine.

Why does the evaporation coating machine coat under vacuum conditions

2023-03-11

If the pressure is not low enough (or the vacuum degree is not high enough), good results cannot be obtained. For example, if aluminum is deposited on the order of 10 2 Torr, the obtained film is not only not bright, but even gray and black. And the mechanical strength is extremely poor.

What is the difference between PVD vacuum coating machine and CVD coating machine?

2023-03-11

Thin film deposition technology is mainly divided into three major processes: physical, chemical, and epitaxy. Physical vapor deposition is referred to as PVD vacuum coating machine. Chemical vapor deposition is referred to as CVD coating machine for short.

In the vacuum chamber, when the particle concentration in the gas phase and the pressure of the residual gas are low enough, these particles can keep flying in a straight line from the evaporation source to the substrate, otherwise, they will collide and change the direction of motion.

Common problems of PVD evaporation process and sputtering process

2023-03-02

Vacuum coating equipment uses two common coating processes, evaporation and sputtering. These two processes are currently the most popular and widely used, and their attention is naturally much higher than other processes.
