plasma cleaner (plasma cleaner), also known as plasma cleaner, or plasma surface treatment instrument, is a new high-tech technology, the use of plasma to achieve the effect of conventional cleaning methods can not be achieved. Plasma is a state of matter, also known as the fourth state of matter, does not belong to the common solid-liquid-gas three states. Apply enough energy to a gas to dissociate it into a plasma state. The “active” components of plasma include ions, electrons, atoms, active groups, excited nuclides (metastable), photons, etc. Plasma cleaning machine is to use the properties of these active components to treat the surface of the sample, so as to achieve the purpose of cleaning, coating, etc.
So what’s the advantage? First, the cleaning object is dry after plasma cleaning, and it can be sent to the next process without drying. Can improve the processing efficiency of the whole process line; Two, plasma cleaning enables users to stay away from harmful solvents to harm the human body, but also avoid the problem of wet cleaning is easy to wash the cleaning object; Three, avoid the use of trichloroethane and other harmful solvents, so that there will be no harmful pollutants after cleaning, so this cleaning method belongs to the environmental protection of the green cleaning method. This becomes more and more important in the context of global concern for environmental protection; Fourth, the plasma generated by the high frequency of the radio wave range is different from the direct light such as laser. Plasma is not very directional, which allows it to reach deep into the tiny holes and dents of an object to complete its cleaning task without much concern for the shape of the object being cleaned. And the cleaning effect of these difficult parts is similar or even better than that of freon cleaning; Five, the use of plasma cleaning, can make the cleaning efficiency can be greatly improved. The whole cleaning process can be completed in a few minutes, so it has the characteristics of high yield; Six, plasma cleaning need to control the vacuum degree is about 100Pa, this cleaning condition is easy to achieve. Therefore, the equipment cost of this device is not high, and the cleaning process does not require the use of more expensive organic solvents, which makes the overall cost lower than the traditional wet cleaning process; Seven, the use of plasma cleaning, avoid the transportation, storage, discharge and other treatment measures of cleaning liquid, so the production site is easy to keep clean and sanitary; Eight, plasma cleaning can be regardless of the treatment of objects, it can deal with a variety of materials, whether metal, semiconductor, oxide, or polymer materials (such as polypropylene, polyvinyl chloride, polytetrafluoroethylene, polyimide, polyester, epoxy resin and other polymers) can be used to deal with plasma. Therefore, it is especially suitable for materials that are not heat resistant and solvent resistant. It can also selectively clean the whole, part or complex structure of the material; Nine, in the completion of cleaning decontamination at the same time, but also can improve the surface performance of the material itself. Such as improving the wettability of the surface, improving the adhesion of the film, etc., which is very important in many applications.
