ABS material pen tongue hydrophilic special vacuum plasma cleaning machine application field :
Note :
The left pen tongue is treated by vacuum plasma, while the right pen tongue is not treated by plasma. You can see that the plasma-treated pen tongue on the left is already hydrophilic and can absorb water well. The right side of the pen tongue without vacuum plasma cleaning, water quickly dripping, not hydrophilic.
The Applications in Plasma Cleaner :
1. Plasma Treatment In the pre-fabrication process of integrated circuits or MEMS, the wafer surface is coated with photoresist, and then photoresist and developed.However, photoresist is only a medium for circular transformation. When the photoresist machine forms nano-graphics on the photoresist, the next step of growth or etching process is needed, and then the photoresist needs to be removed by some method.Plasma degumming machine can achieve this function.It USES radio frequency or microwave mode to produce plasma, at the same time through oxygen or other gases, plasma and photoresist reaction, forming gas is pumped away by vacuum pump.
2. In the production process of microelectronic packaging, due to fingermarks, flux, various cross-contamination and natural oxidation, the surface of devices and materials will form a variety of contamination, including organic matter, epoxy resin, solder, metal salt, etc.These fouling will obviously affect the packaging production process in the relevant process quality.Using plasma cleaning can easily remove these molecules formed in the production process of levels of pollution, ensure the workpiece surface precision contact between atoms with the attached material, effectively improve the bonding strength, lead to improve chip bonding quality, reduce packaging leak rate, improve the performance of components, yield, and reliability.
3. LED point before the silver glue: silver substrate pollutants can cause gum balls, does not favor the chip paste, and easy to cause the chip manual sting a little damage, plasma cleaning can make work surface roughness and hydrophilicity is greatly increased, for silver glue paste tile and chip, and can greatly save the use of silver sol, reduce the cost.
Before LED bonding: improve bonding strength and tensile uniformity of bonding lead.The pressure of the bonding cutter head can be low (in case of pollutants, the bonding head needs to increase the force to penetrate pollutants), and in some cases, the bonding temperature can also be reduced, thus increasing the output and reducing the cost.
Before LED packaging: in the epoxy adhesive injection process of LED, pollutants will lead to high bubble formation, which will lead to low product quality and service life. After plasma cleaning, the chip and substrate will be more precise and colloid combination, the formation of bubbles will be greatly reduced, and the heat dissipation rate and light emission rate will be significantly improved.
4. Plasma Cleaning System for Petri dish/enzyme plate: improve adhesion of cells and biomaterials to clinical diagnostic platforms. Most platforms for cell culture media and other clinical diagnosis are made of synthetic polymer materials.These materials have good inertia, mechanical stability and low manufacturing cost, but at the same time their surface properties have inherent limitations.In particular, they do not provide enough junctions for cells and biologically active molecules to bind effectively to their surfaces.Strong, uniformly distributed junctions are critical for immobilization of biomaterials and in vitro cell culture.For cell propagation and biomolecular adsorption, the surface of synthetic polymer platforms must be modified to improve their performance.It is very reliable and environmentally friendly to use low-temperature plasma technology to solve the adhesion problem of biomaterials to the medium.
5. Plasma Cleaning System Microfluidic devices: microfluidic devices require hydrophilic surfaces so that analytes can flow continuously and gently through microchannels to the detection and processing locations on these devices.This flow can be achieved by various suction, electric osmosis, heat, mechanical and other methods.Microfluidic devices are made of hydrophobic polymeric materials (acrylic acid, polystyrene, polydimethylsiloxane (PDMS)).One of the major problems with these materials due to their hydrophobicity is that crowded bubbles in the microchannel inhibit the flow of the liquid.Plasma treatment oxidizes the surfaces of microchannels, making them hydrophilic and preventing bubbles from forming.The surface charge density during electric pumping also affects the flow rate.Plasma can effectively promote the electroosmotic flow on the surface of charge meter, which is another advantage of plasma treatment of microfluidic devices.
6.Plasma Cleaning System Camera module: in the production process of COMS camera, lens cleaning, circuit welding, packaging and other procedures are involved.The presence of organic pollutants or oxidation layer on the surface of products in these processes will have an impact on the performance and reliability of products. The addition of plasma cleaning process in these processes can remove pollutants from the surface of products, improve the welding and packaging strength, and thus obtain more reliable products.
7. Plasma Cleaning System for Stealth aircraft coating pretreatment, modern advanced aircraft stealth is an indispensable function.However, in order to achieve the stealth effect, the aircraft surface must be coated with a layer of special material that can absorb radar waves. Plasma is used to pretreat the surface of the aircraft shell before the coating, so that the coating binding force is better and it is not easy to fall off, which increases the flight time and reduces the maintenance cost.
8. Plasma Cleaning System for Hole slag removal: hole slag removal is the current plasma technology in the PCB field more applications of the process.Hole inside glue slag refers to in the circuit board drilling process (machine drilling and laser drilling) due to high temperature caused by molecular material melting in the hole wall metal surface glue slag, rather than mechanical drilling processing caused by rough edges, burrs, must be removed before gold plating.This gel residue is also dominated by carbon oxides, which can easily react with ions or free radicals in plasma to generate volatile hydrocarbon oxides, which are finally taken out by the vacuum system.
9. Plasma is used to clean the surface of the circuit board (FPC/PCB) before it is shipped.Generally, downstream customers of PCB will inspect the products with supplied materials, such as Wire Bonding Test, Wire Pull Test, etc., some contamination often leads to failure of the Test when the surface is not cleaned.To avoid the above problems, surface plasma cleaning before shipment has become a standard process.
10. Application in plastic industry

17. Electrical connectors of Plasma Surface Treatment for aerospace
The bonding effect between insulator and wire sealing body in electrical connector has been influencing the development of electrical connector.The adhesion effect is very poor without surface treatment. Plasma cleaning can not only remove oil stains on the surface, but also enhance its surface activity. In this way, it is very easy and uniform to apply glue to the connecting parts during adhesion, so that the adhesion effect can be significantly improved.After the test of many large domestic production plants, the tensile strength of the electrical connectors after plasma treatment has increased exponentially, and the pressurization value has been significantly improved.
18. Plasma Surface Treatment for Kevlar handles
