Application of plasma surface cleaning machine to toys and other commodities

Application of plasma surface cleaning machine to toys and other commodities

Application of plasma surface cleaning machine to toys and other commodities: People’s living standards, health awareness and aesthetic concepts continue to improve. Consumers have higher and higher expectations for the purchase of daily necessities. Rational consumers must make comparisons in many aspects before purchasing. They must be economically applicable and satisfy the appearance The quality of printing and painting, the environmental protection of the production process, the application of new materials, and even the requirements for anti-fingerprint, hydrophobic, antibacterial or flame retardant functional coatings. In fact, plasma surface cleaning machine treatment has unique characteristics in these process solutions. ! Chengfeng Zhizao will give you an example today. Application of plasma surface cleaning machine processing technology in toy aircraft wings: The children's toys made follow high-level safety standards, and the types of adhesives and printing inks all have considerable quality requirements. The plasma surface treatment process can not only improve the surface adhesion of the material, but also make the production process safer and more environmentally friendly. The wing of a toy airplane needs reliable bonding. The surface tension of the wing base material is less than 40 dyne, and the surface tension is above 48 dyne to meet the bonding requirements. After the toy airplane wings are processed by the plasma surface cleaning machine, the surface tension value exceeds 60 dynes, which can fully meet the bonding requirements. Plasma surface cleaning machine processing swimming goggles: The inner layer of ordinary swimming goggles with better quality is generally treated with anti-fog, that is, an anti-fog coating is applied to the PC material. The plasma surface cleaning machine can remove the release agent and increase the adhesion of the anti-fog coating. Before the plasma surface treatment, the contact angle of the water droplets was 82.5 degrees, and the coating quality was not good. Plasma surface treatment is used, and the contact angle of water droplets is 11 degrees, which ensures the quality of the coating. The above are some cases of plasma surface cleaning machine processing technology applied in daily life.

Plasma cleaner is used for wafer-level packaging surface treatment to improve product reliability

Plasma cleaner is used for wafer-level packaging surface treatment to improve product reliability

Plasma cleaner is used for wafer-level packaging surface treatment to improve product reliability: The purpose of the pre-treatment of wafer-level packaging is to remove surface inorganics, reduce oxidation, increase copper surface roughness, and improve product reliability. In industry, plasma cleaners are generally used for ultra-clean cleaning and surface roughening treatment. Wafer Level Package (WLP, WaferLevelPackage) is an advanced chip packaging method, which refers to packaging and testing directly on the wafer after the production of the entire wafer is completed, and then the entire wafer is cut into one Die; the electrical connection part uses a copper bump (CopperBump) instead of wire bonding (WireBond), so there is no need for wire bonding or glue filling process. What are the advantages of using a plasma cleaner for wafer-level packaging surface treatment? The editor will introduce to you. Due to production capacity requirements, vacuum reaction chamber, electrode structure, air flow distribution, water cooling device, uniformity and other factors, there are obvious differences in the design of plasma cleaning machines. Why do we have to choose a plasma cleaner for wafer-level package surface treatment? The reason is simple: the remaining photoresist after the chip is manufactured cannot be cleaned by wet cleaning, but can only be removed by plasma. In addition, since the thickness of the photoresist cannot be determined, it is necessary to adjust the corresponding process parameters through a number of experiments to achieve a very good processing effect.

Application research on plasma treatment technology of plasma cleaner in microwave printed circuit board

Application research on plasma treatment technology of plasma cleaner in microwave printed circuit board

Application research on plasma treatment technology of plasma cleaner in microwave printed circuit board: PTFE has excellent dielectric properties in a wide frequency range, as well as good temperature and wear resistance and chemical resistance, so it is widely used in high-frequency components and seals, such as microwave printed board substrates coated with fluorine Sealing ring, etc. However, due to the low surface energy of PTFE and its very stable chemical properties, it brings great difficulties to the production process of parts, such as metalized surface coating and bonding, and other processing operations must be surface treated first. , Otherwise it is difficult to process or poor reliability after processing. Plasma cleaner plasma is an ionized material, it is a state of matter containing ionic electrons and free radicals. Plasma includes high-temperature plasma and low-temperature plasma, and low-temperature plasma is generally used in plasma processing technology. When polymer materials undergo plasma treatment with plasma cleaners, the surface activation process can actually include two parts. On the one hand, gas particles accelerated by an electric field hit the surface of the material at a high speed, causing plasma etching to make the polymer material The crystal morphology of the surface has changed, which is a physical aspect. On the other hand, the impact of gas on the surface of the material causes a chemical reaction, which generates free radicals on the surface of the material, introduces unsaturated bonds of polar groups and a cross-linked layer, and changes the molecular structure of the surface layer of the material. This is a chemical effect. Both effects can activate the surface of polymer materials to increase wettability, thereby improving the adhesiveness, dyeability and printability of polymer materials. But according to analysis, the effect of chemical action on the surface condition of the material is higher than that of physical action. The characteristic of the plasma treatment technology of the plasma cleaner is that the treatment is concentrated on the superficial layer of the material, so it does not change the bulk properties of the material to be treated. The quality of the hole wall and the pull-out strength of the metallized holes of the PTFE microwave printed board after the plasma treatment technology of the plasma cleaner meets the requirements of the relevant standards. The PTFE microwave printed board is attached after the three-proof coating The focus test is less than level 2, and the film layer is uniform and continuous. These show that the plasma treatment technology has unique advantages in the hole metallization pretreatment and the three-proof coating pretreatment of the PTFE microwave printed board, and it has the advantages of flexible construction, pollution-free, low cost, short treatment cycle, and application. It has the advantages of wide range and low requirements for operators, and is suitable for mass production. Therefore, it has good application prospects in the manufacture of PTFE microwave printed boards.

What are the control valves often used in the process gas control of the vacuum plasma surface treatment machine

What are the control valves often used in the process gas control of the vacuum plasma surface treatment machine: There are many types of gas channel control valves. The gas channel control valves widely used in vacuum plasma surface treatment machines can be divided into manual and automatic according to the operation mode. According to the control mode, they can be divided into pneumatic control valves and solenoid valves, such as According to the working pressure, it can be divided into vacuum valve and low pressure and medium pressure control valve. In the vacuum plasma surface treatment machine, the air path control mainly includes two parts: the process air path control and the vacuum path control. In the process gas control part, commonly used control valves include vacuum solenoid valves, check valves (check valves), and pneumatic ball valves. The following is a detailed introduction to the control valves commonly used in the process control of vacuum plasma surface treatment machines. Commonly used control valves for process gas control: Vacuum solenoid valve: It is necessary to ensure that the working vacuum in the vacuum chamber is within the design range, so the valve connected to the vacuum chamber must meet the requirements of high vacuum sealing, so vacuum solenoid valves are used for conventional process gas control. Since the process gas adopts single-channel control, the selected vacuum solenoid valve is two-position two-way. Pneumatic ball valve: Because the pneumatic ball valve has the characteristics of high vacuum sealing, corrosion resistance, and large diameter, it is used for air circuit control when the vacuum plasma cleaning needs to lead to a special monomer. Choose two-way or three-way, you can choose according to actual needs. Check valve: In the gas circuit control, the check valve is also called the check valve. It mainly plays a role in preventing the backflow of gas, protecting other equipment in the gas circuit control part, and preventing the confluence of reacting gases. Pay attention to the direction of the airflow when using it. There are many types of gas circuit control valves. Its normal operation needs to ensure its vacuum, air tightness and prevent gas backflow. It is very important to choose a suitable control valve. The above is the introduction of the process gas control valve commonly used in the vacuum plasma surface treatment machine, I hope it will be helpful to everyone!

What are the advantages of domestic plasma cleaning equipment plasma equipment

What are the advantages of domestic plasma cleaning equipment plasma equipment: Plasma cleaner is also called plasma cleaner, or plasma equipment surface treatment. It is a new high-tech technology that uses plasma to achieve effects that cannot be achieved by conventional cleaning methods. Plasma is a state of matter, also called the fourth state of matter, and it is not the common three states of solid, liquid and gas. Apply enough energy to the gas to ionize and become a plasma state. The "active" components of plasma include: ions, electrons, atoms, active groups, excited nuclides (metastable states), photons, etc. Plasma cleaners use the properties of these active components to treat the surface of the sample to achieve cleaning, coating and other purposes. As far as the current plasma cleaning equipment is concerned, the plasma equipment has reached the domestic and foreign technical level. Of course, this still depends on the strength of the plasma equipment manufacturer. At present, in China, there are still few with independent R&D and production capabilities.

Which automobile plastic parts can be sprayed with small plasma spraying equipment

Which automobile plastic parts can be sprayed with small plasma spraying equipment

Which automobile plastic parts can be sprayed with small plasma spraying equipment: Plastic products not only reduce the weight of the car body, reduce energy consumption, but also ensure function and safety; through different surface treatment processes, the comfort and decoration of the products are continuously improved. Before silk-screening, bonding, coating and other processes on plastics, the traditional surface treatment methods are manual polishing, flame burning and spraying primer. Now let’s discuss the application of small plasma spraying equipment in the surface treatment of automotive plastic parts. . Small plasma spraying equipment is widely used in the surface treatment of automotive plastic parts. Plastic parts account for more than 1/3 of the total automotive materials, most of which are composite materials, such as PP, ABS, PA, PVC, EPDM, PC, EVA, respectively Processed into bumpers, dashboards, central control panels, door panels, protective panels, engine covers, sealing panels, lamps, shockproof pads, etc. The composite material is made of a combination of multi-physical materials, which can complement each other's strengths and obtain excellent properties that a single material cannot achieve, such as polypropylene (PP) + glass fiber (GF20), polypropylene (PP) + EPDM rubber (EPDM) + Talc (TD20), etc., are widely used in automotive interior parts. Materials similar to PP, EPDM, and ABS+PC have low surface energy and poor wettability, which will affect the quality and surface performance of the screen printing, bonding, coating, and flocking of the material. After using small plasma spraying equipment to process the above materials, it is found that under the action of plasma active particles, the surface performance of the material has been greatly improved, and the tearing ability has also been greatly improved. From the analysis of the results, it can be seen that there are two main reasons: 1. The plasma discharge generated by the small plasma spraying equipment can introduce hydrophilic groups on the surface of the material, such as the hydroxyl group (OH) of the phenol group, the carboxyl group (-COOH) and the carbonyl group (C=O) of the carboxylic acid, thereby improving the surface of the material. The wettability greatly improves the adhesion and bonding strength of the substrate surface. 2. The plasma generated by the small plasma spraying equipment promotes the opening of the molecular bonds of the material, and the cross-linking effect and low molecular weight contaminants are removed. The surface of the material forms a clean and strong contact surface layer, which can also improve the bonding of the contact surface. Strength and binding power. Automotive plastic parts of various shapes and materials can be surface treated with small plasma spray equipment for flocking plastic parts. Not only can the quality control of flocking be guaranteed, but also adhesives that are harmless to the human body and the environment can be selected to reduce the health risks of the operator. Use vacuum plasma spray equipment to perform surface treatment before covering plastic door panels made of polypropylene (PP) + talcum powder (TD20) to enhance the bonding performance of the water-based polyurethane adhesive and plastic parts and improve the tearing force. Plastic products after surface treatment by small plasma spraying equipment, their bonding strength and bonding strength are the same as the electrode structure of the vacuum chamber of plasma surface treatment, discharge vacuum degree, gas type and ratio, gas flow size, treatment time, power supply, etc. The parameters are closely related; the plasma surface treatment has a certain timeliness, so the relevant production should be completed as soon as possible.
