Atmospheric pressure plasma processor for processing metal material welding and surface oil pollution application

Atmospheric pressure plasma processor for processing metal material welding and surface oil pollution application

 Atmospheric pressure plasma processor for processing metal material welding and surface oil pollution application: Atmospheric pressure plasma treatment machine is a type of plasma treatment machine. Due to its own characteristics, it has a wide range of applications in the treatment of many materials, such as electronics, textiles, plastics, polymers, etc., to obtain ideal plasma surface treatment effect. But for the treatment of metal materials, such as aluminum, copper, steel and other materials, atmospheric pressure plasma treatment machines also have great industrial application value. Improving the welding effect and removing surface oil are two application directions. 1. Atmospheric pressure plasma processor is used to improve the welding effect of the weld joint: In general, if you need metal materials to achieve a certain welding quality, you can clean the weld before welding, such as wiping with artificial cotton cloth, cleaning with detergent, etc., but the above methods often fail to achieve the ideal welding effect or Environmental protection requirements, after the introduction of atmospheric pressure plasma cleaning machine, the surface treatment is more clean and thorough, and the welding effect is better. 2. Remove oil and other substances on the surface of metal wires: The surface treatment of metal materials by atmospheric pressure plasma treatment machine can remove nano-scale oil, oxide, scale and other substances on the surface of the material. Because atmospheric pressure plasma cleaning machine has the advantages of high efficiency and easy operation, it is more commonly used in this regard. For the processing of wires, DBD atmospheric dielectric barrier atmospheric plasma processing machine can be used for processing.

The influence of low-temperature plasma generator on the electrical conductivity and biocompatibility of materials

The influence of low-temperature plasma generator on the electrical conductivity and biocompatibility of materials

The influence of low-temperature plasma generator on the electrical conductivity and biocompatibility of materials: Polymers usually have good material properties, but due to their own material reasons, hydrophilicity, adhesion, conductivity and biocompatibility may be poor. Plasma treatment of the material can maintain the excellent performance of the material itself. At the same time, the above-mentioned performance has also been significantly improved. The following focuses on the application of low-temperature plasma generators in material conductivity and biocompatibility. The improvement of the conductivity of the surface of the polymer material by the low-temperature plasma generator: Improving the conductivity of polymer materials is one of the application directions of plasma. Through the graft polymerization treatment of low-temperature plasma generators, PET conductive films with better conductivity can be prepared. Plasma induced grafting technology can also be used to prepare conductive films on the surface of the material. Polymer improves its antistatic performance and improves product utilization. The effect of low-temperature plasma generator on the biocompatibility of materials: When polymer materials are used in the biomedical field, in addition to strength and elasticity requirements, they should also meet biocompatibility standards. The impact on the biocompatibility of materials can be understood from the following aspects. 1. Using a low-temperature plasma generator to treat the surface of HPPA can produce —NH2 groups on the sodium polyhydroxyphosphate HPPA, so that the biological activity of HPPA can be fully exerted. 2. Using argon plasma and oxygen plasma to process polymethyl methacrylate can improve the wettability of the material surface and increase the adsorption capacity. 3. Avoid non-specific protein adsorption on the surface of the material, and keep the surface of the material clean for a long time. It is often used in contact lenses, wound healing materials, urinary catheters, biosensors, etc. 4. Treating the PET film can prolong the retention time of albumin after adsorption and improve the anticoagulant property. 5. The low-temperature plasma generator is used to improve the positioning and fixation of bone and artificial joints, and improve the wear resistance and biocompatibility of joint joints. I believe that with the continuous development and application of science and technology, the application of low-temperature plasma generator plasma surface treatment technology can not only improve the performance of polymer materials in special environments, but also indirectly expand the application range of polymer materials, so that Its application range in processing polymer materials, especially in biomedical materials, is continuously expanding.

After processing the PET film by the plastic plasma processor, observe the processing effect through the contact angle

After processing the PET film by the plastic plasma processor, observe the processing effect through the contact angle

After processing the PET film by the plastic plasma processor, observe the processing effect through the contact angle: Polyester film PET has many excellent material properties, but due to its low surface free energy, poor wettability and viscosity, which limit the production and application of polyester film, plastic plasma processors are often used to process polyester film .  Since the processing process of the plastic plasma processor is microscopic, the SEM scanning electron microscope and contact angle tester are usually used to observe the effect of plasma treatment, and the SEM scanning electron microscope is used to test the treatment effect of the plastic plasma processor on the PET film. Introduce you to use the contact angle tester to test the processing effect of PET film. The PET film is tested before processing: Select the PET film before processing by the plastic plasma processor, measure the surface water contact angle at 6 different positions of the film, and take the average value of the surface water contact angle, and the surface water contact angle of the PET film is 80.7°, which is poor Hydrophilicity. Measure the contact angle of the PET film after 10 seconds and 60 seconds on the plastic plasma processor: Plasma treatment is used for 10 seconds, and then the average value of 6 points is taken to obtain a water contact angle value of 49.1°, compared with 30.9° when the treatment time is 60 seconds. With the help of the change of contact angle, we can understand that the plastic plasma processor can effectively improve the hydrophilicity of the PET film, increase the surface energy and free energy of the material, thereby improving its performance, such as surface wettability and tackiness And printability.

Process optimization of plasma cleaning in IC packaging process of plasma industrial cleaning machine

Process optimization of plasma cleaning in IC packaging process of plasma industrial cleaning machine: IC packaging forms vary widely and are constantly evolving, but the production process can be roughly divided into more than a dozen stages, such as wafer cutting, wire bonding in the chip placement rack, and sealing and curing. Only the packaging that meets the requirements can be put into practical application. , Become a terminal product.  The quality of packaging will directly affect the cost and performance of electronic products. In IC packaging, about 1/4 device failures are related to contaminants on the surface of the material. How to solve the contaminants such as micro particles and oxide layers in the packaging process , Improving the quality of packaging has become particularly important. The problems in IC packaging mainly include solder delamination, virtual soldering or insufficient wire bonding strength. The culprit of these problems is the pollutants on the lead frame and chip surface, mainly microparticle pollution, oxide layer, organic residues, etc. These existing contaminants make the wire bonding between the chip and the frame substrate incomplete or there is a false solder. Plasma industrial cleaners mainly use active plasma to physically bombard the surface of the material or chemical reactions and other single or dual effects, so as to achieve the removal or modification of contaminants at the molecular level of the surface of the material. Plasma cleaners are effectively used in the IC packaging process to effectively remove organic residues, microparticle contamination, and thin oxide layers on the material surface, improve the surface activity of the workpiece, and avoid bonding delamination or virtual welding. The application of plasma industrial cleaning machines and processes in the field of IC packaging will become more and more extensive, and with their excellent performance, they will become a key production device in the field of IC packaging in the 21st century, and become a means of improving the yield and reliability of products in the mass production process. Important technological measures will be indispensable in the future. The cleaning technology of plasma industrial cleaning machines will also continue to develop and expand the scope of application. As far as the current situation is concerned, it is imperative to promote its process technology to the LED packaging and LCD industries.

Plasma surface modification machine pet film plasma treatment SEM scanning electron microscope observation effect

Plasma surface modification machine pet film plasma treatment SEM scanning electron microscope observation effect

The plasma surface modifier can realize the surface modification of PET film materials, so what is the treatment effect? Next, we will understand it through SEM scanning electron microscope. Polyester film materials have been widely used in many industries and fields due to their good fatigue resistance, strong toughness, high melting point, good heat insulation, solvent resistance and excellent anti-wrinkle performance. However, due to the low surface free energy of PET film materials and poor processing properties such as wettability, tackiness and printability, it is necessary to use a plasma surface modifier to modify the surface of the PET film materials. Next, we mainly Observe through the SEM scanning electron microscope to understand the changes of the PET film before and after the plasma surface modifier treatment. Before processing by the plasma surface modifier, observe the PET film material, select the appropriate PET film material, and through the image of the SEM scanning electron microscope, we can know that the surface of the PET film is relatively smooth in the SEM photo with a magnification of 10000× , And some impurities adhere. In the next step, we use the atmospheric jet spinner to process the PET film material in different lengths. Through the comparison of the data, we can see that as the processing time of the plasma surface modifier increases, the surface of the PET film material has different lengths. Regular flake-like structure, and the surface roughness of the PET film has increased, and as the processing time is extended again, a large number of white fine lines composed of nano-sized particles appear on the surface of the PET film. The reason is that the plasma surface modifier treatment has a certain etching effect on the PET film. It can be seen from the microscopic observation of SEM scanning electron microscope that the effect of surface modification treatment on PET film is very obvious.

The skin ports and electrical connectors in the aerospace manufacturing industry are two of them. Low-pressure plasma machines are required for surface treatment to improve The performance of the product meets the needs of users. Let's take a look at this aspect of aerospace plasma technology. Low-pressure plasma machine treatment before aluminum alloy skin coating: In the aviation plasma technology manufacturing industry, the selected skin cover is usually made of aluminum alloy. In order to improve its sealing performance, the fastening part of the cover generally adopts an apron made of NBR vulcanization process. However, after the vulcanization of the rubber material, the phenomenon of glue overflow is likely to occur, which will contaminate the surface of the product to be coated, resulting in insufficient coating adhesion and easy to fall off after coating. After treatment with a low-pressure plasma machine, the adhesion of the coating will be improved to meet the requirements of aviation coating. Low-pressure plasma machine processing for aerospace electrical joints: The aerospace industry has very strict requirements on electrical connectors. If the bonding between the insulator and the sealing body is not ideal, there will be a risk of leakage, which will affect the voltage resistance of the electrical connector. After plasma surface treatment on the low-pressure plasma machine, it can not only remove the oil on the surface of the device, but also enhance the surface activity of the device, make the coating more uniform, help improve the bonding effect, and increase the voltage resistance of the electrical connector, and it can significantly Improve the tensile strength of the device.Low-pressure plasma machine aerospace plasma technology to clean the electrical joints of the skin cover: Aerospace manufacturing should belong to the high-tech field, which has high requirements for the performance and quality of many products.
