      There are many kinds of vacuum coating machines, different products and different application models. According to the industry, it can be divided into seven categories: optical vacuum coater, decorative vacuum coater, winding vacuum coater, hard coating vacuum coater, stainless steel vacuum coater, lamp lighting vacuum coater, continuous line vacuum coater, etc. If it's subdivided, then there are more types. The following is a brief introduction to the difference between sputtering by vacuum coater and evaporation by vacuum coater, hoping to help you:

      The surface component of the target is evaporated in the form of free radicals or ions and treated on the substrate surface. The film is formed in the process of film formation (layer growth of vagus nerve structure with scattering island structure). It is not easy to guarantee the uniformity of the composition of the evaporation coating, which can be controlled with specific factors. However, due to the limited principle, the uniformity of the composition of the evaporation coating is not good for the non single component coating. Sputtering can be simply understood as the use of electronic or high-energy laser bombardment targets, which makes the surface components sputtering in the form of free radicals or ions, and deposition on the substrate surface in the film-forming process, experience, and finally form the film. The equipment sputtering of vacuum coater is divided into many types. At different sputtering rate and evaporation will become a main parameter. The composition uniformity of laser sputtered PLD coating is easy to maintain, and the thickness uniformity of atomic scale is poor (because of pulse sputtering), and the control of crystal orientation (external) growth is more general.

      Maintenance of vacuum coating machine is an important part of daily use of vacuum coating machine, so how to maintain the vacuum coating machine correctly?

1、Do not disassemble blindly. Mechanical problems with the vacuum part are difficult while many companies do not leak detectors and will gradually find out. Why not vacuum may have the following points: perhaps the leakage rate, which is often referred to as leakage; maybe the pumping capacity of the vacuum unit is not enough, pollution or oxidation; maybe a vacuum chamber is too dirty air.

2、A bad sign is found in the routine maintenance of the production equipment, which shall be solved immediately. Do not think that the oil is replaced regularly, waiting for maintenance time, and the rotor pump may be severely worn. For example, it is a big problem to replace the bearing and then wait until it is completely broken, which may lead to the burning of the bogie motor.

3、Regular maintenance, someone will ask a daily maintenance also need regular maintenance? In fact, each equipment has its own life, such as the service life of 2-year oil diffusion pump, which is replaced in advance, and there is no problem in the production stage. As long as you put routine maintenance and regular maintenance, the service life of the equipment is prolonged at the same time, the failure probability in the production process is greatly reduced, and the production efficiency is improved.

4、Develop good hygiene habits. Dust removal equipment and peripheral equipment, petroleum equipment itself is quite large. Dust can produce static electricity and damage electronic components. The oil can make the conduit quench and crack, causing some unexpected problems. We use vacuum coating machine, vacuum equipment and its own particularity. Vacuum equipment, pay attention to sanitation is a vacuum, vacuum is poor, deflation is more.
