Plasma cleaner, all you want to know is here

Plasma cleaner, all you want to know is here

In view of the current support and purchase of our chengfeng intelligent plasma cleaning machine customers, in the process of daily use of the problems encountered, CRF Sing Fung Intelligent Manufacturing engineer with text to summarize the following points (for reference only) : Q: What should I do if I find the test effect is not good? A: Please check whether the color of the pump oil is dull and dirty, and replace the pump oil in time. Q: What if the device doesn't glow? A: 1. Rf lamps do not provide RF; 2. There may be air leakage in the sealing. Q: How do I troubleshoot RF lamps? A: Use the standard test lamp tube of the equipment, put it into the main body cavity, turn on the "RF" switch to "Hi", and judge the RF lamp problem by observing the status of the lamp tube (vacuum is not required in this process). Q: How to solve the sealing problem? A: 1. Ensure that the vacuum pump used can achieve or exceed the minimum pumping speed of 1.4 cubic meters per hour and the ultimate negative pressure is not greater than 200mTorr; 2. Then check whether the vacuum hose, all hose clamps and gas inlet pipe connection parts are correct and tighten, whether the plasma cleaning hatch door is closed correctly, and whether the sealing ring of the door is clean and free of defects. Q: Are there any recommended cleaning process parameters? A: The RF power level should be set to medium or high. 600-800 millitotor pressure and 1-3 minute treatment time are the initial values of the better process parameters. The optimum process parameter values will depend on the sample material and the intended application, and some experiments will be required to determine these optimum values. Q: How to measure the vacuum negative pressure? A: You can ask us to buy corresponding measuring equipment, such as vacuum monitoring unit or gas flow mixer. Q: Why does the pump oil return? A: If the auxiliary pump is an oil pump, the oil may return from the vacuum pump to pollute the system if the internal pressure of the equipment cabin is not reduced immediately after the process is completed. We suggest using A vacuum pump with anti-return suction function. Q: How to clean the inner wall of the vacuum chamber? A: The inner wall, door and O-ring of the vacuum chamber should be cleaned regularly. Please refer to the standard laboratory glassware cleaning method. For example, the surface of the plasma chamber can be soaked with alcohol, acetone or isopropyl alcohol or gently wiped. Plasma has the following major effects on the surface treatment of materials: Activation: greatly improve the surface infiltration performance, form an active surface; Cleaning: dust and grease removal, fine cleaning and static removal; Coating: To provide a functional surface by surface coating treatment; Improve the surface adhesion ability, improve the reliability and durability of surface adhesion. The surface energy of all kinds of polymer plastics, ceramics, glass, PVC, paper, metal and other materials can be improved by atmospheric plasma treatment. Through this treatment process, the surface tension properties of the products can be improved, more suitable for industrial coating, bonding and other treatment requirements.

The application effect of plasma processing technology on the housing

The application effect of plasma processing technology on the housing

Mobile phone is one of the indispensable tools in people's life. It is a headache that after a period of time, you will find that the shell of the phone will lose paint, wear, or the logo will become more and more blurred, seriously affecting the appearance of the phone. And the application of plasma surface treatment technology, to help mobile phone manufacturers to solve the above problems. Plasma technology can be said to be a new environmental technology in the market, instead of the traditional chemical treatment of mobile phone shell surface. The shell of the mobile phone treated by the plasma surface equipment has more wear resistance, which can ensure that the paint will not fall off or grind after a long time of use. Because the plasma surface treatment technology can clean the dust impurities or oil stains left by the mobile phone shell during production, a larger program can improve the activity of the plastic surface, so that the coating effect is very uniform, the coating adhesion effect is better, and the connection between the coating is stronger. Now almost all mobile phone cases will be glued or printed with the brand LOGO or decorative strips, which can make the appearance of the phone more sophisticated. The previous mobile phone shell is composed of ABS, its surface tension is high, generally do not need to deal with. But as PC, nylon, fiberglass and other materials are widely used, the surface tension of the substrate cannot be increased to the required value of glue. The surface tension of the materials to be bonded can be increased to the required value of the glue by the high efficiency of the low-temperature plasma. Plasma treatment can improve the adhesion of plastic surface, remove organic pollutants, interpose polar organic functional groups on the surface, improve surface hydrophilicity and surface wettability. A clean surface and surface wettability are critical to a strong bond between two surfaces. And with the development of plasma technology, as well as the emergence of many companies such as Sing Fung Intelligent Manufacturing specializing in the production of plasma processing equipment, plasma technology has been widely used in the mobile phone industry.

Plasma has high conductivity and strong coupling effect with electromagnetic field. As an important basis for measuring the development level of high and new technologies of a country or a region, new energy industry is also the strategic commanding height of a new round of international competition. Developed countries and regions as well as China have taken the development of new energy as an important measure to conform to the trend of science and technology and promote the adjustment of industrial structure. In addition, China put forward the policy of regional specialization and industrial agglomeration, vigorously planned and developed the new energy industry, and issued a series of supporting policies successively, making the new energy industrial parks spring up like bamboo shoots after a spring rain. New energy is developing rapidly and its production technology is also being improved constantly. In the process, if plasma technology is used, the production process will be better optimized. To give us a better understanding of plasma technology, let's illustrate the application of plasma technology in solar energy. Glass substrate: By using plasma technology, the surface of the material can be blasted, the surface pollutants can be effectively removed, and the surface hydrophilicity of the workpiece can be greatly improved. The included Angle of water droplets after cleaning is less than 5 degrees, which lays a good foundation for the next process. Anodic surface modification: The surface modification of ITO anode by using isotherm technology can effectively optimize its surface chemical composition, greatly reduce the block resistance, and thus effectively improve the energy conversion efficiency and photovoltaic performance of the device. Protective film pretreatment: The surface of the silicon chip is very bright and reflects a lot of sunlight. Therefore, it is necessary to deposit a silicon nitride protective film with very low reflection coefficient. By using plasma technology, the surface of silicon wafer can be activated and its surface adhesion greatly improved.

Atmospheric pressure plasma cleaning machine for mobile phone glass panel processing

Atmospheric pressure plasma cleaning machine for mobile phone glass panel processing

The process of cleaning the glass panel of mobile phone before chemical toughening is very complicated. The non-equilibrium Ar/O2 atmospheric plasma jet generated by the pre-ionization of the needle electrode is a simple cleaning process. The contact Angle between oil and stearic acid on the glass panel was determined with a contact Angle instrument. After 1~2min of plasma jet cleaning, the contact Angle of water was significantly reduced. Scanning electron microscope observation also verified the cleaning effect. In recent years, international famous mobile phones are made of glass as the panel, in order to improve the strength and hardness of the glass panel, chemical toughening is usually used, and before chemical toughening needs to be cleaned, if the cleaning is not good, it will affect the enhancement effect. The traditional cleaning method is to scrub with detergent first, then ultrasonic cleaning with acid solution, alkali solution and organic solvent, which is complicated, time-consuming and easy to cause pollution. Atmospheric pressure low temperature plasma is the rise in recent years, with a variety of cold gas generated by glow discharge plasma, with low breakdown voltage, and metastable molecular ions concentration is higher, electronic high temperature, low temperature neutral molecules, producing plasma even part of the larger, good controllability, do not need to vacuum, can continuous surface cleaning. The higher the concentration of chemical active components in plasma, the better the cleaning effect. Lubricating oil and stearic acid are the most common contamination substances on the glass surface plate of mobile phones. After contamination, the contact Angle of the glass surface to water increases, which affects ion exchange. Traditional cleaning methods are complicated and easy to pollute. Atmospheric pressure plasma cleaning machine generator structure is simple, do not need to vacuum, room temperature can be cleaned, the generated excited oxygen atoms are more active than ordinary oxygen atoms, can be contaminated lubricating oil and stearic acid in the hydrocarbon oxidation, carbon dioxide and water. At the same time, the plasma jet also has mechanical impact force, which plays a role in cleaning, so that the pollutants on the glass surface can be quickly removed from the surface, achieving the purpose of efficient cleaning. Atmospheric pressure plasma cleaning machine features: Optional with a variety of types of plasma nozzle, suitable for different occasions to work, meet a variety of different products and treatment environment; Small plasma equipment, easy to carry; In-line can be installed In the production Line of customer equipment to reduce input cost; Plasma cleaning machine long service life, low maintenance cost.
