The 5 major pretreatment advantages of plasma treatment machine technology process realize online treatment

The 5 major pretreatment advantages of plasma treatment machine technology process realize online treatment: Plasma processor is used for cleaning and material activation. Plasma surface treatment technology can clean aluminum surface conveniently and environmentally. Composite film is usually used for beverage or food packaging because it has good barrier properties. Aluminum foil is used as a composite barrier layer during the processing of composite film. A PE film needs to be added to the aluminum foil to ensure that the aluminum foil does not Direct contact with the food in the package. In this kind of film composite equipment, the aluminum foil is plasma treated and can be closely combined with the PE film. The energy in the plasma of the plasma processor can remove various pollutants such as dust and oil on the surface of the aluminum foil. And the plasma treatment process can completely realize online treatment. In practice, some users use the annealing process to achieve the above effects, but compared with the plasma processor, it consumes time and power. Advantages and characteristics of plasma surface pretreatment of plasma processor: 1. It has complete online integration capabilities (does not affect the original process operation), saves energy and reduces consumption, and is environmentally friendly. 2. The mechanical properties of aluminum foil will not change. 3. Selective and partial cleaning can be achieved. 4. Aluminum foil can be processed on both sides. 5.

Chengfeng Zhizhi plasma cleaning technology has been widely used in many fields

Chengfeng Zhizhi plasma cleaning technology has been widely used in many fields

Chengfeng Zhizhi plasma cleaning technology has been widely used in many fields: Among IC packaging types, Quad Flat Package (QFPS) and Thin Small Outline Package (TSOP) are two types of packaging required by the current packaging density trend. In the past few years, Ball Grid Array Package (BGAS) has been recognized as a standard package type, especially the Plastic Ball Grid Array Package (PBGAS), which provides millions of them each year. Plasma cleaning technology is widely used in PBGAS and flip chip processes and other polymer-based substrates to facilitate bonding and reduce delamination. Plasma cleaning technology is usually introduced in the following steps in IC packaging: before chip bonding and wire bonding, and before chip packaging. Before epoxy conductive adhesive sheet, if the front surface of the carrier is cleaned with plasma equipment, it can improve the adhesion of epoxy resin, remove oxides to facilitate solder reflow, improve the connection between the chip and the carrier, reduce the peeling phenomenon, and improve Heat dissipation performance. When eutectic sintering the chip onto the carrier with alloy solder, if the quality of solder reflow and sintering is affected due to contamination or old surface on the carrier, cleaning the carrier with plasma before sintering is also effective to ensure the sintering quality. Before wire bonding, plasma cleaning the pad and substrate will significantly improve the bonding strength and the uniformity of the bond wire tension. Cleaning the bonding points means removing the thin, contaminated surface. When the IC is plasticized, it is required that the plastic packaging material and various materials such as chips, carriers, and metal bonding feet have good adhesion. If there is contamination or poor surface activity, it will cause the surface layer of the plastic package to peel off. Packaging after plasma cleaning can effectively improve surface activity, improve adhesion, and improve packaging reliability. After the substrate and chip are cleaned by plasma, one of the indicators for detecting whether there is a cleaning effect is the wettability of the surface. The contact angle of the pad packaging tape before and after plasma treatment is measured, and the contact angle of the sample before and after plasma cleaning is: 70° to 80° before cleaning on the solder fill paint, 15° to 20° after cleaning; contaminated gold plating The contact angle of the solder joints before cleaning is 60° to 70°, and after cleaning, it is less than 20° or lower. Of course, the contact angle measurement can only be used as an indication method to obtain the expected results. That is to say, there are also two factors: wire bond thickness and good mold adhesion. Moreover, the cleaning effects of different manufacturers, different products and different cleaning processes are different, which shows that the improvement of wetting characteristics. It is very beneficial for plasma cleaning technology to be used before the packaging process. Plasma cleaning technology has been widely used in many fields and has become an essential equipment in many precision manufacturing industries. Plasma technology combines plasma physics, chemistry, and chemical reactions at the gas-solid interface. It spans a variety of fields, including chemical engineering, materials, and energy. Therefore, it will be extremely challenging and full of opportunities. With the rapid growth of semiconductors and optoelectronic materials in the future, the application demand in this area will also increase.

In 2021, the plasma cleaning machine will sort out 8 questions and answers for customers. Don't miss it

In 2021, the plasma cleaning machine will sort out 8 questions and answers for customers. Don't miss it: Many customers do not know what the functions of the plasma cleaning machine are, and what can be handled. Next, I will answer your questions about the plasma cleaning machine. Is the atmospheric pressure or vacuum plasma cleaner processing time as long as possible? Not necessarily. The cross-linking, chemical modification, corrosion and other effects produced by plasma treatment on the polymer surface are mainly due to the action of plasma, which causes a large number of free radicals to be generated on the surface of the polymer. The results show that with the extension of the plasma treatment time, the discharge power increases, and the intensity of the generated free radicals increases. After reaching a large value, it enters a dynamic equilibrium state; when the discharge pressure reaches a certain value, the free radical intensity will appear a large value That is, under certain conditions, the low-temperature plasma has a deep reaction to the polymer surface. Does the plasma cleaner have a chance to generate ozone? A small amount will be produced. Plasma surface treatment is a "clean" treatment process. Due to the existence of ionized air (O3), an exhaust system can be configured to discharge ozone when needed. Can the plasma cleaner replace the primer? Adopting plasma surface treatment technology, it can completely replace the primer and frosting processes in bonding, coating, flocking, pad printing or coding. The application of this technology not only reduces the scrap rate to a low level, but also achieves continuous environmental protection through the use of solvents. At the same time, it greatly improves the production capacity of the production line, reduces production costs, and meets environmental protection requirements. How long can the activity of the material surface remain after plasma treatment? It is difficult to answer this question, because it is difficult to determine the time that the surface can be retained after treatment, because of the nature of the material itself, secondary pollution after treatment, recurrence of chemical reactions, and so on. In theory, vacuum packaging can delay the plasma treatment time. Generally speaking, we recommend that customers proceed to the next step immediately after the low-temperature plasma treatment reaches high surface energy to avoid the impact of surface energy attenuation. Can the plasma cleaner be used online? The answer is yes, whether it is the bonding of mobile phones, the coating of the casing, the flocking of the sealing strip, the spraying of the sealing strip, or other, the online use of plasma surface treatment systems has become a reality. And according to the specific requirements of the production line of the user unit, the system can be matched with the production line, which can meet the needs of the new line and the transformation of the old line. If the user has general product requirements, the atmospheric online plasma processing system can be integrated into the production line. If the user has higher product requirements or special processing materials, it can also be made into an online vacuum plasma processing system. Meet the various requirements of customers. What special gas is needed for plasma cleaning machine processing? Except for compressed air, on-line processing does not require other special gases. However, if you are using a sub-atmospheric glow discharge device, you can fill it with inert gas such as argon and helium, and perform surface treatment under the condition that the atmosphere is different from air. The reaction gas can produce different treatment effects on the surface of the material, which belong to the process formula.

What are the advantages of plasma cleaning technology What materials can be processed

What are the advantages of plasma cleaning technology What materials can be processed

What are the advantages of plasma cleaning technology What materials can be processed: There are three forms of matter existing around us: solid, liquid and gaseous. Plasma is usually called the fourth state of matter. Ordinary gas is composed of electrically neutral molecules or atoms. Ionized gas is a collection of electrons, ions, atoms, molecules or free radical particles. The total number of positive and negative charges is always equal in value. Based on this plasma composition, ionized gas exhibits the following two properties: 1. Ionized gas is a conductive fluid that can maintain electrical neutrality on a macro scale comparable to the volume of gas. 2. There is a Coulomb force between the charged particles of the ionized gas, which causes the various overall motion behaviors of the charged particle swarm to be affected and dominated by the magnetic field. There are many ways to generate plasma. Natural methods exist between celestial bodies in the universe and the upper atmosphere. Artificial methods-generally discharge methods, radiation methods, vacuum ultraviolet light, lasers, combustion, shock waves, field ionization, etc. Discharge methods include DC discharge, low-frequency discharge, high-frequency discharge, microwave, and induction methods. We use 13.56MHz high-frequency power supply to generate glow discharge in the equipment, and realize various reaction mechanisms in different reaction chamber conditions, thereby producing different process effects. The important advantage of plasma cleaning technology lies in its versatility. It can be used for surface activation, cleaning, etching and deposition of a variety of materials. Why use plasma cleaning technology? This process directly applies a high-energy plasma stream to the surface to be cleaned to achieve the purpose of plasma cleaning. Choosing different gas types and ratios can meet many plasma cleaning requirements. For example, oxygen plasma can be used to oxidize organic deposits; inert argon plasma can be used to mechanically wash away particle contamination; hydrogen plasma can eliminate metal surface oxidation and so on. The application of plasma cleaning technology to clean organic matter on the surfaces of metals, ceramics and plastics greatly enhances the adhesion and bonding force on the surfaces of these materials. With the deepening of the research on this technology, its application has become more and more extensive. In the electronics field, this technology can be used for cleaning and etching of hybrid circuits, PCB boards, SMT, BGA, lead frames and flat panel displays; in the medical field, this technology should also be used to improve various catheters, ultra-fine catheters, and filters. Key indicators such as smoothness and wettability of medical devices such as sensors. In the large-scale integrated circuit and discrete device industries, plasma cleaning technology is generally used in the following key steps: 1. De-glue, treat the silicon wafer with oxygen plasma to remove the photoresist; 2. Plasma cleaning of the device substrate before metallization; 3. Plasma cleaning before bonding the hybrid circuit; 4. Plasma cleaning before bonding; 5. Plasma cleaning before capping the metalized ceramic tube; 6. The controllability and repeatability of the plasma cleaning technology process is reflected in the advantages of economy, environmental protection, high efficiency, high reliability and easy operation in the use of equipment.
