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.

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.
