What role does atmospheric plasma cleaning equipment play in the production of lithium battery pole pieces

What role does atmospheric plasma cleaning equipment play in the production of lithium battery pole pieces

What role does atmospheric plasma cleaning equipment play in the production of lithium battery pole pieces: When it comes to automotive lithium batteries, I believe everyone is no longer unfamiliar with them. The production process of automotive lithium battery pole pieces is more complicated, including slurry preparation, slurry coating, pole piece rolling, pole piece slitting and pole piece drying. It is a relatively new process to use atmospheric plasma cleaning equipment to process the pole pieces before coating. Therefore, what role does atmospheric plasma cleaning equipment play in the manufacturing process of lithium battery positive and negative plates? How does this help the product? The positive and negative electrode materials of the lithium battery are coated on the metal film to make the positive and negative electrodes of the automobile power lithium battery. Before the electrode material is coated, the metal film must be cleaned to improve the coating effect. The material of the metal film is generally aluminum foil or copper foil. In the past, the cleaning is done by wet processing. Even if the surface is cleaned with ethanol and other solutions, this cleaning method is likely to cause invisible damage to the lithium battery and other components. Will produce some residue. Due to these shortcomings, in the subsequent manufacturing process, the dry surface treatment method of atmospheric plasma cleaning equipment is gradually adopted. It can not only remove organic matter, make the surface of the film rough, improve the wettability of the metal film surface, but also improve the coating. The uniformity of the layer is conducive to improving thermal stability, safety and reliability. If you have any questions about the purchase or use of the equipment, please feel free to inquire.

Research on spraying surface modification coating of magnesium alloy plasma cleaner

Research on spraying surface modification coating of magnesium alloy plasma cleaner

Research on spraying surface modification coating of magnesium alloy plasma cleaner: Magnesium alloys have low density, high specific strength and specific stiffness, and have extremely important application value and broad application prospects in aerospace, transportation, 3C products (communication and computing) and other industries. In addition, magnesium alloy also has good biocompatibility, mechanical compatibility and degradability as a new type of biomedical implant material and has also received extensive attention. Although magnesium alloy has outstanding advantages, it has low wear resistance and poor corrosion resistance, which limits its application to a certain extent. Therefore, improving the corrosion resistance and wear resistance of magnesium alloys under different working conditions is a problem that must be solved to expand its application. The surface modification technology of plasma cleaners can increase the surface hardness, improve corrosion resistance, and enhance wear resistance by adjusting the composition and structure of the modified surface without affecting the strength of the material. Appropriate surface modification treatment of magnesium alloys is of great significance for exerting the performance advantages of magnesium alloys. Plasma cleaning machine spraying technology has the advantages of high productivity, fine coating structure, high bonding strength with substrate, low porosity, wide sources of spraying materials, and low cost, making it suitable for traditional fields such as wear-resistant coatings and corrosion-resistant coatings. The application is more extensive. Due to the differences in physical and chemical properties between the magnesium alloy substrate and the ceramic coating, residual stresses will be generated during the preparation of the coating, which will reduce the bonding strength between the substrate coatings and affect the overall performance. The metal/ceramic gradient coating sprayed by the plasma cleaner uses the metal phase as the transition layer and the ceramic phase as the surface layer, or as the thickness of the coating increases, the content of the ceramic phase gradually increases and the content of the metal phase decreases accordingly, which is a good solution. The problem of the mismatch of metal and ceramic properties. It greatly reduces or eliminates the stress in the coating and improves the bonding strength between the coating and the substrate. Plasma cleaner spraying technology prepares modified coatings on the surface of magnesium alloys, which greatly improves the surface hardness, wear resistance and corrosion resistance of magnesium alloys, and expands the application range of magnesium alloys.

What are the differences before and after processing the mobile phone shell antenna by the atmospheric rotating plasma cleaner

What are the differences before and after processing the mobile phone shell antenna by the atmospheric rotating plasma cleaner

What are the differences before and after processing the mobile phone shell antenna by the atmospheric rotating plasma cleaner: In today’s smart phone market, whether it’s a high-end smart phone or a cost-effective, affordable smart phone, many of its components will use the surface treatment process of an atmospheric rotating plasma cleaning machine, just to name a few, such as touch screens, PCBs, speakers , Buttons, shells, batteries, etc., their mobile phone shells have insufficient adhesion and poor wear resistance; mobile phone antennas are not firmly bonded, and are prone to delamination and cracking. These components will use atmospheric rotating plasma during production, processing and assembly. Cleaning machine processing technology, next we use the mobile phone shell and mobile phone antenna to understand what effect the surface treatment process of the atmospheric rotary plasma cleaning machine has on it. The plasma surface treatment technology of the plasma cleaner can not only clean the surface organic matter of plastic, metal, glass, ceramics and other materials, but also remove the plasma surface activation on the surface of the mobile phone shell, effectively improving the bonding of the mobile phone shell during the printing and coating process. The effect is that the coating between the shell and the substrate can be firmly bonded, thereby solving the problem of weak bonding. In addition, after plasma treatment, the coating of the mobile phone shell will be very uniform, and the appearance will be more beautiful and beautiful. The wear resistance will also be greatly improved, and the paint will not be rubbed for a long time. After the mobile phone antenna is treated with an atmospheric rotary plasma cleaner, the reliability of the bonding is improved, and the problem of delamination or cracks in the bonding of the mobile phone antenna is solved. The bonding of mobile phone antennas is realized between two or more different materials. The general process is to glue glue to the surface of the substrate, and then glue the FPC to solidify it. Due to the large amount of dirt on the surface of the substrate, there are fine particles before bonding and curing, or the surface energy of the substrate itself is low, so the bonding effect is not ideal and the reliability is difficult to guarantee. In the actual production process, delamination and Crack phenomenon. The plasma surface treatment process of the atmospheric rotary plasma cleaning machine can effectively clean and activate the surface of the substrate, improve the bonding performance, improve the reliability of bonding, and solve the problem that the mobile phone antenna is not easy to bond and fall off.

The camera module products involved in vacuum plasma surface treatment equipment cleaning include many products, such as infrared cut-off filters, Mobile phone cameras, car cameras, and vacuum plasma surface treatment equipment are how to clean these products to prepare for the next process. Plasma treatment of infrared cut filter: The infrared cross-section filter makes full use of the precision optical coating technology. The optical substrate is alternately coated with high and low refractive index optical films, which can achieve high light transmission and near-infrared cross-section filters in the visible light region. By adding in the imaging system The infrared cross-section filter can block some of the infrared rays that will affect the imaging quality, thereby improving the imaging quality and obtaining a better visual presentation. Why does this kind of optical filter adopt plasma surface treatment process? In order to remove impurities and residues on the surface of the infrared cut-off filter, ultrasonic cleaning and centrifugal water washing are usually used, but this method alone cannot form an ultra-clean substrate surface. At this time, it is necessary to introduce vacuum plasma surface treatment equipment.

Research on the improvement of interlayer separation defects by the de-drilling process of plasma cleaning equipment

Research on the improvement of interlayer separation defects by the de-drilling process of plasma cleaning equipment

Research on the improvement of interlayer separation defects by the de-drilling process of plasma cleaning equipment: With the continuous upgrading of the electronic information industry, especially the advent of the "Internet +" era, higher requirements have been placed on printed circuit boards (PCB) for signal transmission, and higher requirements have also been placed on PCB processing technology. Interlayer separation (ICD) is a common defect in the copper immersion process. ICD defects have a significant impact on the reliability of PCB products.  The low Dk characteristics of high-speed materials have extremely high advantages in signal transmission. This characteristic is very consistent with the needs of 5G products. Therefore, it is increasingly applied to 5G products. However, due to the physical and chemical properties of the material during the processing process, after drilling, the excess slag in the hole is difficult to be removed by the traditional chemical de-drilling method, which brings great hidden dangers to the product functionality, and the product needs to be further improved. Reliability. Plasma cleaning equipment Plasma cleaning is to use the ionization effect of a strong electric field to form a fourth state of plasma through the ionization of a mixture of CF4 and O2 through the radio frequency power of the electric field under vacuum conditions. The epoxy resin residue is converted into volatile organic fluoride, so as to achieve the effect of removing drilling dirt. Plasma cleaning equipment not only has a strong drilling dirt removal ability, but also has a great advantage in the long-term reliability of the product. The plasma cleaning equipment is dry processing, and it is done under the directional action of the electric field, so it avoids the traditional way of drilling pollution. The fluffing agent attacks the position of the glass fiber on the hole wall, which can greatly reduce the whitening and whitening of the glass fiber. Abnormal stratification also has great advantages in preventing CAF. The processing temperature affects the effect of drilling dirt removal. Because the Plasma processing process is mainly a chemical change, in a chemical reaction, temperature is one of the important factors affecting the chemistry. Increasing the temperature can increase the reaction rate, and vice versa, the de-drilling rate will decrease. In the same way, in the process of Plasma de-drilling, increasing the reaction temperature can improve the ICD. In the process of de-drilling, we need to obtain a clean surface of the hole wall for post-process processing. The hole wall is the part that participates in the reaction during the processing of the plasma cleaning equipment. The size of the exposed area is related to the effect of the de-drilling . If the cavity of the equipment is regarded as a whole, in the same constant cavity, the resin area of ​​the hole wall affects the amount of bite for removing dirt. During Plasma processing, power directly affects the amount of plasma generated. The more plasma ionized by the electrode, the better the effect of de-drilling the hole wall, and vice versa; We know from the knowledge of physics that the electric field ionizes the gas, and it needs enough energy to make the gas appear in an excited state, and the energy is expressed as processing power in the plasma cleaning equipment. The greater the processing power of the plasma, the more sufficient the ionization effect of the plasma, and the better the effect of de-drilling.
