The role of plasma cleaning machine equipment plasma surface treatment of tiny holes

The role of plasma cleaning machine equipment plasma surface treatment of tiny holes

The role of plasma cleaning machine equipment plasma surface treatment of tiny holes: Plasma cleaning equipment is mainly suitable for surface modification treatment of various materials: surface cleaning, surface activation, surface etching, surface deposition, surface treatment and plasma-assisted chemical vapor deposition. With the miniaturization of the diameter of HDI plates, traditional chemical cleaning processes can no longer meet the requirements of cleaning blind hole structures. The surface tension of the liquid makes it difficult for the liquid to penetrate into the holes, especially when processing laser-drilled micro blind holes. not good. At present, the hole cleaning process applied to micro-buried blind holes mainly includes ultrasonic cleaning and plasma cleaning of plasma cleaning machine equipment. Ultrasonic cleaning is mainly based on the cavitation effect to achieve the purpose of cleaning. It belongs to wet processing, and the cleaning time is longer and depends on The decontamination performance of the cleaning liquid increases the problem of waste liquid treatment. The commonly used process at this stage is mainly the plasma cleaning process. The plasma treatment process is simple and environmentally friendly, the cleaning effect is obvious, and it is very effective for the blind hole structure. Plasma cleaner equipment cleaning refers to the directional movement of highly activated plasma under the action of an electric field, and the gas curing reaction occurs with the drilling dirt on the hole wall, and the generated gas products and some unreacted particles are discharged by the air pump. Plasma is generally divided into three steps when cleaning the blind holes of HDI boards. In the first stage, high-purity N2 is used to generate plasma, while the printed board is preheated to make the polymer material in a certain activated state; the second stage is with O2, CF4 is the original gas, which produces O and F plasma after mixing, which reacts with acrylic acid, PI, FR4, glass fiber, etc. to achieve the purpose of de-drilling; the third stage uses O2 as the original gas, and the generated plasma and reaction residues Make the hole wall clean. In the plasma cleaning process, in addition to the plasma chemical reaction, the plasma also physically reacts with the surface of the material. The plasma particles knock off the atoms on the surface of the material or the atoms on the surface of the attached material, which is helpful for cleaning the etching reaction. With the development of materials and technology, the realization of the buried blind hole structure will become smaller and more refined; when the blind hole is electroplated and filled, it will be more and more difficult to use the traditional chemical desmear method , And the cleaning method of plasma treatment of plasma cleaning machine equipment can well overcome the shortcomings of wet desmear, and can achieve a better cleaning effect on blind holes and micro holes, so as to ensure that the blind holes are electroplated and filled. good effect.

Plasma cleaning equipment low-temperature plasma treatment of the surface performance of the fluorine-containing coating on the solar backplane

Plasma cleaning equipment low-temperature plasma treatment of the surface performance of the fluorine-containing coating on the solar backplane

Plasma cleaning equipment low-temperature plasma treatment of the surface performance of the fluorine-containing coating on the solar backplane: Photovoltaic power generation is a hot topic at the moment, especially the concept of distributed photovoltaics, which further makes photovoltaic power generation a clean energy that residents can afford. The use environment of solar panels is harsh, so the performance of solar backplanes is very important. As the protective layer of solar cells, the solar back sheet must have excellent weather resistance, high insulation, low water permeability and good adhesion performance. There are currently two main types of solar backplanes: 1: Coated back sheet, using fluorine-containing resin coated on the surface of the substrate PET polyester film; 2: Glue-coated composite back sheet, using a layer of fluorine film on the surface of the base material polyethylene terephthalate (PET) film.  In actual use, it can be freely combined according to the use environment, performance requirements, price and other factors. Fluorine-containing material has good weather resistance, but it also has high water and oil repellency, which is not conducive to bonding with solar encapsulation film EVA. Plasma cleaning equipment low-temperature plasma treatment of the surface of fluorine-containing materials, improve the bonding performance of fluorine-containing materials and solar packaging film ethylene-vinyl acetate copolymer (EVA), and provide stable and effective protection for solar cells. The electrons in the low-temperature plasma of the plasma cleaning equipment obtain energy from the electric field and become free high-energy electrons. They collide with atoms and molecules in the gas to produce excitation and ionization phenomena, and the excited molecules, atoms, ions and free radicals generated thereby are all The extremely unstable ones have high chemical reactivity and are prone to some reactions to generate new compounds. When the fluorocarbon coatings are processed, the surface layer can be etched to form new properties, or cause cross-linking and polymerization. Under the same processing speed, the processing power of the plasma cleaning equipment plasma processor increases, the contact angle decreases, and the surface tension increases. After reaching a certain power, the surface tension and contact angle tend to be stable. The peeling force between the backsheet and EVA is also consistent with the changes exhibited by the changes in surface tension, and tends to be stable. After low-temperature plasma treatment, the surface energy of the fluorine-containing coating increases, the contact angle decreases, and the peeling force of EVA increases, thereby improving its adhesion to EVA. With the increase of plasma cleaning equipment's low-temperature plasma processing power and time, it is conducive to the improvement of its surface performance.

Plasma bonding process and effect analysis of PDMS matrix plasma cleaning equipment

Plasma bonding process and effect analysis of PDMS matrix plasma cleaning equipment

Plasma bonding process and effect analysis of PDMS matrix plasma cleaning equipment: PDMS is a common organic polymer material. It has the characteristics of low raw material price, short production cycle, good durability, flexible packaging method and its ability to form a good seal with a variety of materials. It has many advantages in electronic medicine and other aspects. Huge application prospects. Although PDMS is widely used, PDMS has shortcomings such as high hydrophobicity and strong adsorption of non-polar substances, making PDMS unable to bond with its own glass metal flakes and other materials under normal conditions to limit its use. PDMS is cleaned by plasma on the surface of the equipment. The above operations can be achieved after modification. Plasma cleaning equipment processing is a process in which a high-frequency generator ionizes a gas in a vacuum state to generate plasma (the fourth state of the substance) for surface activation modification. Plasma is an ionized gaseous substance composed of atoms deprived of some electrons and positive and negative electrons produced by ionization of atoms. It is the fourth state of matter existing in addition to solid, liquid, and gas. These highly active particles interact with the surface of the material to be treated, activate the surface of the inert polymer to improve its hydrophilicity, enhance the interaction of the interface and make it easier for monolayer molecules to diffuse to the surface, so that the surface of the PDMS matrix can be modified Realize its bonding with a variety of materials. There are three main process parameters that affect the PDMS bonding effect in plasma cleaning equipment processing: RF power, air flow, and modification time. At present, most of the researches using oxygen as the reaction gas have found through preliminary experiments that the bonding effect of air as the reaction gas can also meet the experimental requirements. The bonding loading pressure also has a non-negligible effect on the PDMS bonding effect after plasma treatment. The PDMS PDMS bonding effect is one of the important focuses in this field. To determine the PDMS PDMS bonding effect is mainly to measure the bonding strength. The T-peel method can be used to determine the bonding strength between two PDMS films. PDMS-PDMS bonding integrity is also one of the important indicators of bonding effect. Bonding integrity is a necessary condition for the normal use of the microfluidic chip. Part of the bonding will cause the microfluidic chip to fail. Plasma cleaning equipment processing does not produce a damage layer on the surface, it is a non-destructive processing process, and the surface quality is guaranteed; because it is carried out in a vacuum, it does not pollute the environment and ensures that the cleaned surface is not polluted again, which is effective and environmentally friendly. Chengfeng Zhizao is committed to the research and development of plasma technology, if you have any questions, please feel free to consult.

Five types of cleaning machine alarms and troubleshooting for vacuum plasma equipment

Five types of cleaning machine alarms and troubleshooting for vacuum plasma equipment

Five types of cleaning machine alarms and troubleshooting for vacuum plasma equipment: Plasma equipment is a process equipment used for plasma surface treatment of materials or products, and vacuum plasma equipment is one of them. How to deal with failures or alarms during use? Now Chengfeng Zhizao has listed some common problems, hoping to help you. Pump thermal overload protection for vacuum plasma equipment: When the plasma processing equipment has vacuum pump thermal overload protection, check whether the parameters of the system have changed, because when the equipment is suddenly powered off, all the parameters of the system will be reset to zero, which will cause this kind of alarm of the plasma equipment. In the case of checking the system parameters unchanged, it is necessary to confirm whether the thermal relay is automatically protected, and press the reset button to start the vacuum generation system of the vacuum plasma processing system. If there is no automatic protection, check again whether the circuit is broken or short-circuited. If there are no abnormalities above, check the vacuum pump again. The air discharge pressure of the vacuum plasma equipment is too low: When this kind of failure occurs, it may be that the gas is not turned on or the gas is consumed too much. It is necessary to check whether the gas solenoid valve used to break the vacuum at the bottom of the cavity is working properly, and whether there is an open circuit or a short circuit. Countdown failure of vacuum plasma equipment vacuum pump: In case of failure, please check the pumping capacity of the vacuum pump first, and then press the reset button after troubleshooting. Material leakage and unclosed vacuum door will affect the pumping capacity of the vacuum pump. In addition, check each node in the plasma vacuum processing system one by one. See if there is a bad or damaged pipe connection. Alarm when CDA pressure is too low: This type of alarm is also known as the low breaking air pressure alarm. It is caused by insufficient compressed air pressure. It mainly occurs in plasma processing equipment equipped with high-vacuum pneumatic baffle valves. If this type of alarm occurs, it is necessary to check whether the CDA is normally supplied with air. Device side. Determine whether the air supply pressure is too high or too low, whether the alarm value of the pressure reducing gauge is set correctly, and check the electrical wiring. Alarm when the vacuum gauge fails: The vacuum gauge failure alarm may be caused by damage to the vacuum gauge. It is necessary to check the control circuit of the vacuum gauge to determine whether the vacuum gauge is faulty or short-circuited. The emergency stop of the vacuum plasma processing system cannot be reset or has been pressed, and the emergency stop switch needs to be turned on: At this time, check whether the emergency stop is suppressed. If not, check the emergency stop line. Chengfeng Zhizao focuses on the research and development and manufacturing of plasma technology.

Surface plasma treatment equipment low-temperature nitrogen plasma modified PAN film and its anti-pollution properties

Surface plasma treatment equipment low-temperature nitrogen plasma modified PAN film and its anti-pollution properties

Surface plasma treatment equipment low-temperature nitrogen plasma modified PAN film and its anti-pollution properties: With the rapid development of membrane science and technology, it is difficult for a single membrane material to meet actual needs, such as chemical stability, corrosion resistance, hydrophilicity, and pollution resistance. Therefore, it is necessary to physically or chemically modify the membrane material to improve Its comprehensive performance. Polyacrylonitrile (PAN) has become a widely used ultrafiltration membrane material because of its excellent chemical stability, thermal stability and bacterial resistance. It has entered the practical stage in the fields of food, pharmaceutical fermentation, oil-water separation, emulsion concentration, and paint recovery. 　　 However, because the polyacrylonitrile membrane has poor hydrophilicity and is easily contaminated by macromolecules such as protein solutions, it is imperative to modify the polyacrylonitrile membrane to improve its separation efficiency, performance and extend its service life. Surface plasma treatment equipment Plasma is a gaseous treatment technology that combines physics and chemistry. It acts in the nanometer range of the surface of the membrane material and does not affect the body characteristics of the membrane. The modification process is pollution-free and simple and quick to operate. It has been obtained in the society Rapid development. Surface plasma treatment equipment low-temperature plasma modified membrane, the flow of clean water increased, the Zeta potential of the membrane surface and membrane pores increased by 69.4% and 58.66%, respectively, the surface plasma treatment equipment low-temperature plasma technology surface modified polyacrylonitrile ( PAN) ultrafiltration membrane, and vapor phase grafted acrylic monomer (AA) method to improve the anti-fouling performance of the membrane. 　　Using atmospheric pressure dielectric barrier discharge plasma technology, the surface of the polyacrylonitrile ultrafiltration membrane is grafted with acrylic acid and polyethylene glycol methacrylate containing hydrophilic groups to obtain a hydrophilic ultrafiltration membrane. The ultrafiltration membrane modified by DBD plasma has good anti-biological pollution performance. 　　 Under normal circumstances, the surface of the ultrafiltration membrane contains hydrophilic groups, the better the wettability of the membrane. As the discharge power gradually increased, the contact angle also increased and showed regular changes. This may be because with the increase of the discharge power, the dissociation degree and average energy of plasma active particles (free electrons, positive and negative ions, metastable atoms, free radicals, etc.) have increased, which is caused by the interaction with the film surface. The more active sites, the enhanced modification effect. 　　Using surface plasma treatment equipment low temperature plasma modification to introduce hydrophilic groups on the surface of the membrane, the contact angle is reduced, and the hydrophilic properties of the PAN super membrane are improved. However, due to the poor timeliness of the plasma-modified ultrafiltration membrane, its hydrophilic properties will gradually decrease with time. Therefore, in order to overcome this shortcoming, gas phase grafting of acrylic monomers (AA) with hydrophilic structure is adopted, and the graft polymerization is carried out in the form of covalent bonds on the surface of the membrane, which can not only attract hydrophilic groups but also overcome the timeliness. , So that the ultrafiltration membrane can maintain its anti-pollution performance for a long time after modification.

Rejecting the secondary pollution of products handled by vacuum plasma cleaners should standardize this operation

Rejecting the secondary pollution of products handled by vacuum plasma cleaners should standardize this operation

Rejecting the secondary pollution of products handled by vacuum plasma cleaners should standardize this operation: During the use of the vacuum plasma cleaner, the product was contaminated by oil. What caused it? In fact, with regard to the secondary contamination of the product during the treatment process, it is likely that the following operation is not standardized. In other words, after the plasma cleaning equipment alarms, part of the oil and gas generated by the vacuum pump is sucked back into the vacuum chamber due to improper operation of the equipment. Have you ever made such a mistake during the operation? Let's continue to watch. Improper operation mainly means that when the plasma equipment fails and stops, the operator does not perform the operation of breaking the vacuum and starting the vacuum pump in a timely and standardized manner, but directly clicks the start button on the automatic interface. At this time, if there is residual oil and gas at the end of the vacuum pump, it will be sucked back into the indoor vacuum under the action of the negative pressure of the indoor vacuum, causing the pollution of the vacuum products. Since the vacuum plasma cleaner will automatically close its high-vacuum flapper valve after the alarm is stopped, but the vacuum chamber is still in a high-vacuum state at this time, and the high-vacuum to the vacuum pump end is in a normal pressure state, there is a pressure difference, if this Press the start button for a moment, the high-vacuum pneumatic baffle valve will open, and the oil and gas will be sucked backwards, contaminating the vacuum chamber, and then contaminating the product. Therefore, how should we perform correct and standardized operations when equipment alarms and shutdowns occur? When the vacuum plasma cleaner has an alarm and shutdown, the vacuum breaking action should be carried out in time at this time to confirm whether the vacuum pump has stopped due to the alarm. If the vacuum pump stops, you need to start the vacuum pump before you can continue to use it. The interlock function of the control circuit has been added. This method fully considers the mobility of the operator and the execution of the operating procedures and other factors, and optimizes the equipment control. Improved the interlocking function between the start of the vacuum pump and the start of the high-vacuum baffle valve, which can ensure that the vacuum pump will not open when the high-vacuum pneumatic baffle valve is not started, thereby preventing misoperation from returning oil to the vacuum chamber. The above are two relatively simple and practical methods of prevention and transformation, which are simple, effective, safe and reliable. However, in order to ensure product quality, it is still necessary to standardize the operation process of vacuum plasma cleaning equipment, that is, when the equipment fails and shuts down, it should be entered in time The manual interface performs the vacuum breaking action, because if the equipment is down for a long time, the product is always in a high vacuum state, and the indoor vacuum will also affect the processing effect of the vacuum plasma cleaner on the product.
