How to check the vacuum pump when the vacuum plasma cleaner is slow in pumping speed

How to check the vacuum pump when the vacuum plasma cleaner is slow in pumping speed

How to check the vacuum pump when the vacuum plasma cleaner is slow in pumping speed: In an article a few days ago, I introduced the effect of material infiltration on the evacuation speed of the vacuum plasma cleaning machine. Although the material infiltration is one of the reasons for the slow down of the vacuum plasma processing system, in fact, the vacuum pump It is very common for problems to cause sabotage and lower efficiency. So how do we check and maintain the vacuum pump correctly? In the vacuum plasma cleaner, when the vacuum capacity drops, it can be run under no load first. If a higher vacuum limit is tested, such as 8Pa, it can be judged that the vacuum pump is faulty. At this time, the vacuum pump needs to be Split inspection. The key inspection contents are as follows. 1. Inspection of the vacuum oil pump: The processed product itself contains a lot of impurities, and the vacuum oil is not replaced in time, the vacuum oil will become turbid and viscous. This kind of inspection is mainly to check the oil condition in the vacuum pump chamber. If the quality of the oil drops, it is necessary Replace with new oil. 2. Inspection of the filter element and filter screen of the suction filter of the vacuum pump: This inspection is mainly to check whether there is a large amount of impurities deposited in the vacuum pump filter element and filter screen of the vacuum plasma cleaner, which causes the mesh to be blocked and affects the suction speed. If it is blocked, it should be cleaned in time. 3. Check the vacuum pump chamber: This inspection is mainly to check whether there is a large amount of deposits and adhesion of impurities in the vacuum pump chamber. This is because after the vacuum pump is turned on, the impurities in the chamber will begin to flow. If there are too many impurities, the rotor of the vacuum pump will be stuck. Scratches and damages of the rotary vanes at all levels, the sealing of the oil circuit, the break of the exhaust valve, and many other situations have affected the evacuation capacity of the vacuum processing equipment, and even caused the damage of the main components of the vacuum pump. 4. Inspection of the exhaust valve plate: This inspection is mainly to check the breakage of the exhaust valve sheet. The exhaust valve acts as a one-way valve in the vacuum pump. If the one-way valve breaks, it will fail, resulting in a reduction in the evacuation capacity of the vacuum plasma processing system. 5. Inspection of rotating pieces at all levels: This project mainly checks whether there is wear and damage to the rotary vanes of the vacuum pump at all levels. If the abrasion or damage is serious, the gap between the rotary vanes will increase and the pumping capacity will be affected. 6. Check the sealing ring: If the sealing ring of the vacuum pump chamber is damaged, it is easy to cause oil leakage and affect the pumping speed. 7. Check the check valve: For example, if the check valve of the vacuum plasma cleaner is damaged, the vacuum capacity of the equipment will also be reduced.

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.

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.

Vacuum plasma cleaning technology improves the printing and bonding quality of glass cover plate coating

Vacuum plasma cleaning technology improves the printing and bonding quality of glass cover plate coating

Vacuum plasma cleaning technology improves the printing and bonding quality of glass cover plate coating: Glass covers are widely used in the display industry, and everyone is familiar with the glass covers used for LCD panels and touch panels. In terms of materials and applicable parts, the glass cover uses the glass layer on the surface of the liquid crystal and TP. In order to ensure the quality of its products, that is, to improve the printing effect, bonding effect and coating effect, ultrasonic cleaning is often used for surface treatment in the past. In the industry's trend toward precision, do you also feel that the coating, printing and bonding of glass cover plates are also difficult to achieve the desired results? In the next step, you may want to learn about the processing technology of low-pressure vacuum plasma cleaning technology. 1. Limitations of ultrasonic cleaning methods: The ultrasonic cleaning method uses its multiple effects in the liquid to disperse and peel off the dispersion and peeling of large-particle contaminants on the surface of large particles, so as to achieve the purpose of cleaning. Since the ultrasonic cleaning method can only remove large-particle contaminants, only Using the ultrasonic cleaning method, some organic substances and particles invisible to the naked eye are often left on the surface of large-particle contaminants. Due to the existence of these substances and particles, the subsequent coating, printing, bonding and other processing effects are not ideal. The vacuum plasma cleaning technology can not only remove organic substances and particles that are difficult to distinguish by the naked eye, but also activate and etch the glass surface, greatly improving the coating, printing, and bonding effects, thereby improving the production efficiency of the glass cover. 2. An example analysis of the actual treatment of the glass cover by the vacuum plasma cleaning machine: In actual customer cases, the customer's requirements for the plasma treatment of the glass cover plate are: the glass printing area is clean, the surface is free of oil stains or black spots, and the surface is smooth. Without the effect of plasma treatment, its surface will have some contaminants and particles before it is plasma cleaned. At this time, the effect of subsequent treatment is not ideal. Using a vacuum plasma cleaning processor for plasma treatment, the effect of plasma treatment can be clearly seen. At this time, the next process is carried out, the effect is up to the requirements, and the product yield is improved.

Application of atmospheric pressure plasma cleaner surface treatment technology in microelectronics industry

Application of atmospheric pressure plasma cleaner surface treatment technology in microelectronics industry

Application of atmospheric pressure plasma cleaner surface treatment technology in microelectronics industry: At present, the surface treatment technology of atmospheric pressure plasma cleaners has gradually become an indispensable type of technology in the production and processing process of the microelectronics industry. However, in the fields of microelectronics and automobile manufacturing, people often call plasma surface treatment equipment "plasma cleaning machine". With the development of process technology, plasma treatment equipment is more and more widely used, and plasma treatment technology is gradually becoming Familiar to the public. On this day, we would like to communicate with you about the application of atmospheric pressure plasma cleaner plasma surface treatment technology in the microelectronics industry. If you encounter problems in the manufacturing process, I hope this article can help you. Traditional cleaning methods, such as mechanical cleaning, water cleaning, solvent cleaning, etc., are not thoroughly cleaned, and the surface of the processed material will still have a thickness of several nanometers to tens of nanometers, which affects the welding and bonding properties of the device. In industrial production, the reliability requirements of products are not strict, and there is a certain amount of cleaning residues during use. However, with the gradual improvement of the requirements for precision and reliability, more and more microelectronics manufacturers Looking for new surface cleaning methods, and atmospheric pressure plasma surface treatment technology can achieve ultra-clean and thorough cleaning of the device surface, improve product reliability, increase product yield, and reduce production costs. In terms of pollution sources, the pollutants on the surface of microelectronic devices are mainly the adhesion of foreign molecules and the two kinds of oxide layers formed naturally on the surface of the device in contact with the environment. The surface treatment technology of the plasma cleaner can effectively treat these two types of surface contaminants, but the appropriate treatment gas must be selected first. Oxygen and argon are more common in the surface treatment of electronic components. Therefore, how do oxygen plasma cleaning equipment and argon plasma cleaning equipment achieve efficient cleaning? 1. Oxygen can be ionized under the action of alternating electric field to form a large number of oxygen-containing active groups, which can effectively remove organic pollutants on the surface of the component, and at the same time can adsorb the groups to the surface of the component, effectively improving the component For example, in microelectronic packaging technology, plasma treatment before plastic packaging is also a typical application. The surface of the component after plasma treatment has a higher surface energy, which can be combined with the molding compound, and reduce the delamination and pinholes that occur during the molding process. 2. Argon gas can form argon ions, and can use the self-biased sputtering generated on the surface of the material to eliminate foreign molecules adsorbed on the surface and effectively remove surface metal oxides. Plasma treatment before wire bonding of microelectronics is a typical process. On the surface of the pad after plasma treatment, organic pollutants and oxides are removed, which can effectively improve the reliability of the welding line and the welding line, and improve the yield rate. In addition to the selection of process gas, various factors such as plasma power supply, electrode structure, reaction pressure, etc., will have different effects on the treatment effect during the surface treatment process of the atmospheric pressure plasma cleaner.
