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.

Plasma treatment makes polymers stick more tightly

Plasma treatment makes polymers stick more tightly

(a) polytetrafluoroethylene/polydimethylsiloxane /Cu, (b) polytetrafluoroethylene/polydimethylsiloxane /SUS430, (c) polytetrafluoroethylene/polydimethylsiloxane/glass. Polydimethylsiloxane treated with plasma technology can be used as a substitute for strong adhesives to adhere fluoropolymers to other types of materials. Polymer has the characteristics of light weight, high strength and good stability, and has become an essential material in modern life. However, most polymers do not naturally adhere to other materials. Therefore, it needs to be surface treated with adhesive or corrosive chemical treatment. This has caused great trouble in the food and medical fields, where pollution must be strictly controlled. It is urgent to realize clean bonding of industrial polymers. According to Scientific Report, a team of researchers at Osaka University in Japan has found a breakthrough. They developed a plasma treatment that not only made vulcanized rubber and polytetrafluoroethylene (PTFE) adhere to each other, but also to other materials. "PTFE is sprayed by a helium plasma at 200 ° C and sticks to unvulcanized rubber," says Yuji Ohkubo, author of the paper. This problem has been solved in our earlier research. But vulcanized rubber is more challenging. To this end, we have developed a novel plasma treatment for vulcanized silicone rubber that is tightly bound to PTFE. The silicone rubber mentioned by Nkubo Yuji mainly refers to polydimethylsiloxane (PDMS). The key to the adhesion of PTFE is thermo-assisted plasma treatment. For PDMS, the trick is to bombish the surface with a plasma jet, breaking the silicon-carbon bonds on the surface and converting them into silanols. The newly produced silanols are more surface active and can bind to PTFE. Then, under high pressure conditions, silanols form hydrogen bonds with oxygen-containing functional groups in the treated PTFE, thus forming a strong bonding effect. By bonding the two materials together, the new material combines the chemical resistance, scale resistance and slip resistance of PTFE with the elasticity of silicone rubber. PTFE can be replaced with perfluorane, which is more transparent, if the material transparency is required. More significantly, when the back of the PDMS is also treated with plasma technology, it can bond with copper or even glass. Plasma-treated PDMS act like double-sided tape, allowing the polymer to adhere "cleanly" to other material surfaces. Co-author Katsuyoshi Endo explained: "The new adhesion effect could make PTFE and PDMS more versatile in medical and food technologies. We hope that this non-binder bonding technology will broaden the range of polymer applications in high-tech fields."

The application prospect of plasma technology

The application prospect of plasma technology

Plasma is the fourth state of matter different from solid, liquid and gas. Matter is made up of molecules, which are made up of atoms, which are made up of positively charged nuclei and negatively charged electrons. When applied at a high energy, the electrons leave the nucleus, and the matter becomes a plasma of positively charged nuclei and negatively charged electrons. Seemingly "mysterious" plasma is actually not rare, the most common plasma is high temperature ionized gas, such as arc, neon lights and fluorescent light gas, as well as the sun, lightning, aurora, and so on. Plasma has been widely used in mobile phone industry, semiconductor industry, new energy industry, polymer film, material anti-corrosion, metallurgy, coal chemical industry, industrial three waste treatment, medical industry, LCD display screen assembly, aerospace and other fields, with a potential market value of nearly 200 billion US dollars per year. The interaction between charged particles in plasma is very active, and the surface modification of various materials can be realized by using this characteristic. The application of plasma technology in surface technology is mainly used in the following aspects. 1. Plasma surface treatment: In order to improve the performance of cutting tools and moulds, the metal surface can be permeated with nitrogen, carbon, boron or carbon nitrogen by plasma. The characteristic of this method is that instead of adding a covering layer to the surface, the material structure and properties of the matrix surface are changed. In the process of processing, the workpiece temperature is relatively low, do not make the workpiece deformation, which is very important for precision parts. This method can be applied to a variety of metal substrates, including glow discharge nitriding, nitrocarburizing and boriding. 2. Plasma for material surface modification: Change wettability (also known as wettability). The surface wettability of some organic compounds has great influence on the adhesion of pigments, inks and binders, as well as on the surface flashier voltage and surface leakage current and other electrical properties. The measure of wettability is called the contact Angle. Different treatments of materials have different effects on the contact of antennae. 3. Application of plasma in the electronics industry: In the past, the production process of LSI chip core was replaced by chemical method and plasma method, which not only reduced the temperature in the process, but also changed the chemical wet method of gelatinizing, developing, etching and removing gelatinizing into plasma dry method, making the process simpler, facilitating the realization of automation and improving the yield of finished products. The resolution and fidelity of the chip core processed by the plasma method are both high, which is beneficial to the improvement of integration and reliability. Plasma-deposited films can be used to protect electronic components. Plasma-deposited conductive films can be used to protect electronic circuits and equipment from damage caused by static charge accumulation. Plasma-deposited films can also be used to manufacture capacitor elements. In addition to the above part of the application of plasma technology, plasma technology in the mobile phone industry, semiconductor industry, new energy industry, polymer film, anti-corrosion materials, metallurgy, industrial "three wastes" treatment and health care industry, LCD assembly, aerospace and other fields has wide application, the prospects of the vast, impressive!
