Linear automatic plasma cleaning machine improves the bonding force of PI polyimide sputtering copper plating

Linear automatic plasma cleaning machine improves the bonding force of PI polyimide sputtering copper plating

Linear automatic plasma cleaning machine improves the bonding force of PI polyimide sputtering copper plating: PI polyimide material is one of the important materials in the preparation of FPC, but the surface of polyimide material has poor hydrophilicity and poor bonding strength with copper film, which greatly affects the quality of FPC products. How does the automatic plasma cleaner solve the problem of poor bonding strength between polyimide material and copper film! On the linear automatic plasma cleaner, oxygen or argon plasma can physically bombard the PI surface, changing the surface from smooth to rough, thereby increasing the surface area combined with the copper film and increasing the free energy of the polyimide surface. When bombarded with argon plasma, certain chemical bonds on the surface of the PI material can be broken, so that some of them overlap to form chemical crosslinks, and the other part is combined with metal atoms, which is beneficial to improve the bonding force of the sputtered copper film. The linear automatic plasma cleaner introduces a large number of hydrophilic compounds, and uses an oxygen plasma cleaner to treat the PI substrate. After plasma activation, a large number of hydrophilic hydroxyl groups can be generated on the surface of the PI substrate to improve the hydrophilicity of the PI substrate. When magnetron sputtering copper produces hydroxyl, it can react with copper to generate Cu-O bond, which enhances the bonding force between copper and polyimide.

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.

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 application of plasma cleaning technology in the cleaning treatment of photocathode accessories

The application of plasma cleaning technology in the cleaning treatment of photocathode accessories

The application of plasma cleaning technology in the cleaning treatment of photocathode accessories: In addition to the super-cleaning function, the plasma cleaner can also change the surface properties of certain materials under certain conditions as needed. Plasma acts on the surface of the material to recombine the chemical bonds of surface molecules and form new surface characteristics. For some special-purpose materials, the glow discharge of the plasma cleaner in the ultra-cleaning process enhances the adhesion, compatibility and wettability of these materials. Therefore, plasma cleaning, as a new type of cleaning technology, will be widely used in the fields of optics, optoelectronics, materials science, biomedicine, microfluidics, etc. Vacuum optoelectronic devices represented by low-light image intensifiers are widely used in national defense, scientific research and other industries, and are highly valued in China. The low-light-level image intensifier uses a photocathode to generate corresponding photoelectron images under the excitation of input photons from the scene, thereby converting weak or invisible radiation images into electronic images. In the ultra-high vacuum tube, the electronic optical system exerts great influence on the photoelectrons. A strong electric field is focused by an electron optical lens (or through a microchannel plate electron multiplying method), bombarding the phosphor screen with high-energy electrons to emit light, realizing the multiple increase of incident light energy, thereby producing the corresponding photon image imaging visible to the human eye Device. The low-light image intensifier is a vacuum photoelectric imaging device. Its production and manufacturing process is complex and diverse. Its production and manufacturing show two major characteristics: ultra-high vacuum, ultra-high cleanliness, especially the removal of hydrocarbons and hydrogen pollution. The stability of it is very important. Therefore, the device has very high cleanliness requirements for parts, accessories and semi-finished components in the process of circulation. Take the auxiliary parts used in the manufacture of photocathodes of image intensifiers: antimony base base and single tube base as examples. These two auxiliary parts are the main tools in the photocathode manufacturing process. The insulation performance of the ceramic terminal directly affects the photocathode. Manufacturing quality of production. The structure of the antimony base seat and the single tube seat is compact, the ceramic terminals are densely distributed, and the groove space at the metal rod is narrow. It is very difficult to scrub with tools. Previously, chemical immersion (RBS cleaning agent) and ultrasonic cleaning methods were used for the antimony base seat and single tube seat with poor insulation performance of the ceramic terminal. These cleaning methods were used to treat the antimony base seat and single tube seat with poor insulation performance of the ceramic terminal. The socket is cleaned. Although the insulation performance of the ceramic terminal of the antimony base has been improved to a certain extent, after a short period of use, excessive leakage current of the ceramic terminal will occur repeatedly, which is manifested as incomplete cleaning. The application of this method of cleaning makes the cleaning frequency of the antimony base seat and the single tube seat too high, and the frequency of use is low. At the same time, the use cost is increased, and the environmental pollution is also increased. Plasma cleaning technology is used to clean antimony base holders and single-tube holders with poor insulation performance of current ceramic terminals. When cleaning with a plasma cleaner, the entire quartz cavity of the plasma cleaner is filled with plasma, and any part of the workpiece, including small grooves, slits, and micropores that cannot be cleaned by ordinary cleaning methods, can be completely The cleanliness. At the same time, the use of plasma cleaning can fundamentally improve the insulation performance of the ceramic terminal, extend the life cycle of the antimony base seat and the single tube seat, improve production efficiency, reduce production costs, and reduce environmental pollution. Fully understand the application of new cleaning technology in the cleaning treatment of photocathode accessories, innovate the original cleaning method, improve the cleaning effect of the image intensifier accessories, and improve the product process yield and work efficiency.

It is highly efficient, environmentally friendly and reliable, and is considered to be an effective and sustainable power generation technology in the 21st century. Among various fuel cells, Renewable Fuel Cell (RFC) is a medium-to-high energy energy storage system, which is mainly composed of two parts: water electrolysis cell and fuel cell. Water electrolysis generates hydrogen and oxygen through water cell electrolysis, and then passes through The electrical energy generated by the fuel cell converts hydrogen and oxygen into water. This process is characterized by recyclable and renewable energy. Renewable fuel cells are currently mainly used in energy storage hybrid systems and portable energy systems for spacecraft and spacecraft.

It is especially suitable for mobile power sources and various portable power sources. It is an electric vehicle and other transportation tools. The ideal power supply. The development of renewable fuel cells and proton exchange membrane fuel cells is an important part of the development of new energy technologies. Conventional PEMFC chips mainly include thin-film electrodes and bipolar plates. A core component of the bipolar plate battery. Its functions are as follows: (1) Separate oxidizer and reducing agent; (2) Collect current for cooling the battery system; (3) Provide flow channels for reaction gas and water; (4) Support the membrane electrode. Therefore, the ideal bipolar plate material must be a good electrical and heat conductor with good air resistance, good corrosion resistance, low density, high strength, and easy processing and forming. The electrode plates of some batteries are plated on metal strips with positive and negative electrode materials. When the metal strips are plated on the electrode materials, the metal strips need to be cleaned and treated effectively with a plasma cleaning machine (surface treatment machine). Plasma cleaning is a kind of dry cleaning, which mainly relies on the activation of reactive ions in plasma to remove stains. The invention can effectively remove dirt, dust, etc. in the battery, prepares for pre-welding of the battery, and reduces defective products. In order to prevent battery safety accidents, it is usually necessary to externally treat the battery core to insulate, prevent short circuits, protect circuits, and prevent scratches. It can clean the end plate of the insulating board, surface dirt, surface roughness, and enhance the adhesion and adhesiveness. Several functions of plasma active particles: enhancing effects, such as bonding, bonding, welding, coating, and de-glueing. The pollutants to be removed include organic matter, epoxy resin, photoresist, oxide, particle pollutants, etc. Therefore, different plasma cleaner (surface treatment machine) processes should be used to treat different pollutants, and the corresponding Process gas. If you have any questions or want to know, please feel free to consult the plasma technology manufacturer of Chengfeng Zhizhi.
