Application of low temperature plasma generator in industry

Application of low temperature plasma generator in industry

        The principle of surface treatment of atmospheric jet low-temperature plasma generator: The air flow of the cold arc plasma jet gun can produce oxygen-based active substances containing a large number of oxygen atoms. These oxygen atoms can be sprayed on the surface of the material to separate the adhered to the surface of the material. The organic pollutant element C can be converted into carbon dioxide and then removed; at the same time, it can improve the contact performance, thereby increasing the strength and reliability of the connection.Industrial low temperature plasma generator         Industrial applications of low-temperature plasma generator surface treatment technology:         (a) Pre-welding treatment Stainless steel sheet butt welding is widely used in industry. For example, the inner barrel of a solar water heater is made of 0.4mm stainless steel sheet rolled into a cylindrical shape and welded. In order to meet the welding requirements, the welding part must be cleaned. The current cleaning method is a wet method, which uses a chemical cleaning agent to scrub manually. The cleaning cost is high, the pollution is large, and it is difficult to realize automation. Low-temperature plasma generator cleaning technology is a dry cleaning technology, applied to the pre-treatment of thin plate butt welding, which can replace traditional manual chemical cleaning agents, reduce cleaning costs, improve welding quality, reduce environmental pollution, and realize welding areas Automation of cleaning. (b) Surface treatment of plastic sheets, such as wood plastic, is a new type of material that can replace wood, but the surface coating is very difficult, which greatly limits its scope of application. If chemical treatment is used, the cost is high and the pollution is large. Therefore, using low-temperature plasma air jet treatment, the surface of the material will change significantly: the color is slightly lighter, the reflectance is reduced, and the surface is in a matte state; the surface is slightly rough when touched by hand; the adhesion performance of the spray paint is greatly improved improve. The bonding force before and after plasma treatment can be tested. Test method: Use a scraper to make a scratch on the surface of the part to be tested, and use a soft brush to scrape off the debris on the surface. Use scotch tape to stick the markings, there should be no air bubbles between the tape and the sample, keep it for 1 to 2 minutes, and tear the tape at a constant speed of 60 degrees. Judge the bond strength by observing the integrity of the scribe line and the square.         In our daily life, such as door seals on cars, we often use rubber processed products. The surface should be painted or woven. If there is no plasma treatment with a low-temperature plasma generator, adhesion is not easy. If chemical cleaning is used, it will be offline and pollute the environment. The ideal solution is to use online plasma treatment.         (d) Plasma jet for glass and metal plates can treat glass and metal surfaces, not only can effectively remove organic pollutants from floating dust in the atmosphere, but also can change the surface properties to make it last long enough. Thereby improving the joint strength of the product. In addition, atmospheric pressure plasma cleaning can be applied to the surface of organic and metallic materials.         Plasma refers to a gas that is partially or completely ionized, and the sum of the positive and negative charges of free electrons and ions is completely offset, and it appears as neutral electricity on a macroscopic scale. Plasma, also called plasma, is an ionized gaseous substance. It is composed of atoms deprived of some electrons and positive and negative electrons generated after atoms are ionized. It exists widely in the universe. It is usually considered to remove solids and liquids. In addition to qi, the fourth state of matter existence.         Low-temperature plasma generators are mainly used for surface modification treatment of various materials: surface cleaning, surface activation, surface corrosion, surface grafting, surface deposition, surface polymerization and plasma-assisted chemical vapor deposition.         After being processed by a special metal low-temperature plasma generator, the surface morphology of the material undergoes microscopic changes. After the metal material is processed by Dyne’s low-temperature plasma surface processor, the bonding force of the material surface reaches 80 dynes or more, which can meet various bonding, Spraying, printing and other processes can achieve the effect of removing static electricity at the same time.

Oxygen Plasma Activation Mechanism Silicon-silicon Direct Bonding Process Research

Oxygen Plasma Activation Mechanism Silicon-silicon Direct Bonding Process Research

Oxygen plasma activation mechanism silicon-silicon direct bonding process research:         As a packaging and manufacturing technology in the semiconductor manufacturing field, silicon direct bonding (SDB) is playing an increasingly important role. SDB bonding allows polished semiconductor wafers to be joined together without the use of adhesives. Oxygen plasma activation mechanism         This technology can be widely used in many fields such as microelectronics, micromechanics, and optoelectronics. Therefore, in-depth study of this technology is of great significance for advancing the application of wafer bonding in the semiconductor industry.         The current silicon wafer bonding technologies mainly include: anode bonding, interposer bonding, and direct bonding. Anode bonding requires that the silicon wafer to be bonded is connected to the positive electrode of the power supply, the glass is connected to the negative electrode, and the glass silicon wafer is heated to a certain temperature, so it cannot be used for direct silicon-silicon bonding. The interposer bonding uses an interposer to bond the two wafers.         Among them, the intermediary is generally formed on the surface of the wafer to be bonded in advance through methods such as deposition and growth, and the two wafers are re-used to form a reliable connection during the bonding. The high annealing temperature required for the bonding of the interposer is prone to large thermal stress, and some undesirable chemical reactions occur, resulting in device damage or defects and pollution.         The silicon-silicon direct bond has good compatibility at low temperature, rarely generates stress, and has good electrochemical properties, which has important research value. The silicon-silicon direct bond is closely related to its surface energy. Wet and dry activation techniques are usually used to increase the surface energy of silicon. Among them, dry methods such as oxygen plasma activation techniques have less pollution and can better improve the bonding quality.         The influence of oxygen plasma activation process parameters on bonding. The activation process parameters include the effect of oxygen plasma activation time, activation power (ie RIE power) and oxygen flow rate on the bonding result, so as to optimize the activation process parameters in process applications select.         The activation power plays a decisive role in the concentration and energy of the oxygen plasma, and has a huge contribution to changing the chemical characteristics of the flow of the silicon wafer surface, which is the focus of process research.         Although the range value corresponding to the oxygen flow rate is smaller than the activation power, it also has an important effect on the oxygen plasma concentration. According to the process principle of activating the surface of silicon wafer by oxygen plasma, oxygen plasma oxidizes the surface of silicon wafer when treating the silicon wafer to improve hydrophilicity and generate a large number of hydroxyl groups, which plays a vital role in bonding.

The plasma cleaning machine can remove the dirt on the surface of the magnetic steel to improve the bonding effect

The plasma cleaning machine can remove the dirt on the surface of the magnetic steel to improve the bonding effect

The plasma cleaning machine can remove the dirt on the surface of the magnetic steel to improve the bonding effect:         There are many types of small magnetic steel products, which have a wide range of uses. They have high requirements for the cleanliness and bonding strength of the product surface. How can plasma cleaning machines effectively remove surface contaminants and improve bonding effects? Plasma cleaning machine         The main types of small micro-magnetic steel sheets are aluminum-cobalt magnetic steel, rare earth strong magnetic (neodymium iron boron) bonded rare earth permanent magnetic steel, ferrite magnetic steel, etc., which have been widely used in smartphone acoustic devices, such as speakers, earphones, Microphones, etc., as well as micro-motors, air-conditioning motors, computer-driven motors, magnetic therapy products, etc. Most small magnetic steel sheets have higher requirements for product surface cleanliness, and are generally produced in dust-free workshops. In addition, there are certain requirements for product surface adhesion strength. Therefore, is there a more reliable method to remove the contaminants on the surface of the magnetic steel, so as to improve the effect of bonding products?         Different from cleaning in the traditional sense, the surface treatment process of the plasma cleaning machine is dry cleaning throughout the entire process, without waste water and other waste gas pollutants. The plasma cleaning machine can remove the contaminants on the surface of the magnetic steel, and at the same time form active groups on the surface of the magnetic steel to improve the morphological characteristics of the surface of the magnetic steel.         After the plasma cleaning machine is used to treat the miniature magnetic steel sheet, the surface energy of the magnetic steel sheet will change significantly, which can be assisted by the contact angle tester. In general, the smaller the water drop angle, the higher the surface energy. Conducive to obtain better bonding effect. The following is the comparison before and after plasma surface treatment of small magnet steel.         The angle of water droplets before treatment is 110.99 degrees;         The angle of the water droplets processed by the plasma cleaning machine is 32.5 degrees;         The main reasons for the different angles of water droplets before and after plasma surface treatment:         1. The cleaning function of the plasma cleaning machine, which can remove organic pollutants on the surface of the magnetic steel to form a clean surface;         2. The activation effect of the cleaning equipment produces a large number of hydrophilic active groups on the surface of the magnetic steel, which improves the surface energy. At this time, the bonding is carried out as soon as possible to obtain better results.         If you want to know more, please feel free to inquire at any time, free of charge to answer your questions about the dirty surface of the material.
