Vacuum plasma surface cleaner for special purpose applications

Vacuum plasma surface cleaner for special purpose applications

Vacuum plasma surface cleaner for special purpose applications Vacuum plasma surface cleaning machine is specially used for IC chips and other materials surface treatment to increase adhesion, with a layer of vacuum plasma corrosion with a few atom thickness of the material, some IC chips only produce 10nm between electronic components, and there are manufacturers plan to reduce it to 5nm. Vacuum plasma surface cleaner What is the special application way of vacuum plasma surface cleaner? Vacuum Plasma Surface Cleaner deals with whether a clean surface will allow a binder to bond to a different surface. For example, when rubber parts are bonded to plastic tools. Plastic and rubber usually use different binders. Therefore, the approach of using the same binder for both materials is to ensure the cleaning and activation of each surface. Plasma activates the free radicals left on the surface of plastic or rubber material, making the bond between the material surface and the adhesive more tightly. This free radical occurs on the surface of the material and is chemically unstable; They are extremely strong in binding to adhesives. The production of these free radicals is also useful when printing surfaces, which usually do not accept ink. If printing is done on a bright or smooth surface, the plasma must be activated so that the printing surface can accept ink and produce a stain resistant effect. A vacuum plasma surface cleaner can be used to coat surfaces to enhance their luster, a process called plasma polymerization. Vacuum plasma is used to etch a layer of material several atoms thick to make small integrated circuit chips. Is the vacuum plasma surface cleaner used for cleaning other than activating the surface? Examples of plasma bonding: The shift registers can be glued together during assembly, and printing on smooth surfaces such as plastic or PTFE can result in poor finished product quality and a large amount of ink that does not adhere to the surface. It is difficult to bond other materials on smooth plastic products because different polymers require different adhesives, so the vacuum plasma surface cleaner can be used to improve the adhesion effect after cleaning.

Introduction of plasma surface treatment technology for three dimensional objects

Introduction of plasma surface treatment technology for three dimensional objects

Introduction of plasma surface treatment technology for three dimensional objects In plasma surface treatment technology, the energy of the particles is usually around a few to a dozen electron volts, which is much larger than the bonding energy of polymer materials (a few to a dozen electron volts), which can break the chemical bonds of organic macromolecules, thus generating new bond energy; However, it is far lower than high-energy radiation, which only involves the surface of the material and does not affect the performance of the matrix. Electrons in the plasma surface treatment technology in the thermodynamic equilibrium state, has the very high energy, can damage the material surface molecular bonds, and improve the particle chemical reactivity heat plasma (strong), and the temperature close to room temperature neutral particles, this for heat-sensitive provides favorable conditions of surface modification of polymers. After low temperature plasma surface treatment, the surface of the material will undergo many physical and chemical changes, or corrosion roughness phenomenon, or the formation of dense crosslinking layer, or the introduction of polar oxygen-containing groups, respectively improve the hydrophilicity, bonding, absorbability, biocompatibility and electrical properties. The surface morphology of the material can be obviously changed by using the appropriate process conditions, and the introduction of a variety of oxygen-containing groups makes the surface from non-extremely difficult to stick to a certain polarity, easy to stick and hydrophilic, which is conducive to bonding, coating and printing. Introduction to plasma surface treatment technology Plasma surface treatment of the material has the following effects: 1, activity: significantly improve the wetting, the formation of active surface; 2, cleaning: remove dirt and oil, fine cleaning and static electricity; 3, coating: through the surface coating treatment, provide functional surface, 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 and metal can be obtained by constant pressure plasma treatment. Adopts this kind of treatment technology, can improve the product surface tension performance, accords with the industry respect to the coating, the adhesive and so on treatment request. Such as: 1, liquid crystal display coating processing, casing and buttons and other junction surface of the oil injection screen printing, PCB surface in addition to the glue cleaning, cleaning before film paste, wire, cable before the processing of code injection and so on. 2. The processing of lampshade, brake pad and door seal tape before pasting in the auto industry; 3, in the mechanical industry, the metal parts for the small, harmless cleaning treatment, lens coating treatment, a variety of industrial materials between the connection and sealing before the treatment. 4, in the printing packaging pasting box machinery, the edge of the sealing position of the pre-gluing treatment. 5, in the medical device industry, before the needle and plastic catheter bonding treatment and so on. Plasma surface treatment technology is used to modify the surface of a three-dimensional object. High-frequency AC high voltage is applied to both ends of the electrode to make the air between the two electrodes produce plasma area to produce gas arc discharge. The plasma reaches the surface of the treated object under the airflow, thus realizing the modification of the three-dimensional object surface. Ion surface treatment technology is an economical, safe and thorough cleaning method. Contaminants are removed from the treated substrate surface without affecting the properties of the host material. Plasmas are widely used in the circuit board industry, including for conformal coating before PCB cleaning and for cleaning lead frames during packaging. Compared with other surface cleaning technologies, plasma treatment has significant advantages. Widely used in metal, plastic, glass, ceramics and other materials. And this approach is environmentally friendly, plasma cleaning does not need to use dangerous chemical solvents, do not need to worry about environmental pollution problems greatly save costs.

Application of low temperature plasma surface modification machine technology and equipment on materials

Application of low temperature plasma surface modification machine technology and equipment on materials

Application of low temperature plasma surface modification machine technology and equipment on materials Low-temperature plasma surface modification machine technology equipment can be used to prepare hydrophilic substances, change the product surface value for printing use, after treatment and then use adhesives or ink can be very good to achieve the bonding effect, usually called plasma surface modification, this method is used to make the object become hydrophilic (wettability). A hydrophobic surface repels water and is considered non-wettable. Duck feathers, for example, are hydrophobic, and water flows over the surface rather than over the feathers. Low-temperature plasma surface modification machine technology equipment PTFE or plastic is often treated with low-temperature plasma surface modification machine technology equipment, so that the surface is more "wet-able", thus improving the adhesion and printing performance. This is a common purpose when we perform plasma cleaning. The low-temperature plasma surface modifier technology device actually changes the surface of the material by several layers of monolayer film, leaving free radicals on the surface and binding with glue or ink. This is especially useful when bonding different surfaces, such as plastic or metal. The surface is different, the binder is different; This makes it difficult to find a suitable adhesive. Look for connections that use plasma to change the surface, leaving extra electrons on the plastic or rubber surface. This can make the surface adhesion, strength greatly improved. Plastic surface is smooth, usually printed or adhered to other materials, such as plastic or metal bonding treatment is not strong. When these smooth surfaces are treated with plasma, the added surface allows for direct printing without coating. This effect is quite brief, ranging from a few hours to a few days, and there is enough time to complete the process of processing the material. Low-temperature plasma surface modification machine technology, such as vacuum plasma treatment, has more advantages than pneumatic plasma technology. Negative pressure plasma system makes the action of plasma longer and provides excellent surface improvement treatment. Atmospheric plasma systems are usually easier to install on assembly lines, or to handle large products in small areas.
