With the continuous progress of science and technology, the update and iteration of consumer electronic products such as computers, mobile phones, TVs, and smart watches are accelerating. The key to winning in the competition is to enhance the high-end, high-quality and differentiated products, so as to promote the consumer electronics industry to increasingly strict requirements for product parts, among which improving the surface hydrophobicity, wear resistance and corrosion resistance of parts is a key to the consumer electronics industry, and coating on the surface of parts is one of the commonly used methods to improve its performance.
As the mainstream protection technology in the electronics industry, plasma nano coating has won the favor of major electronics manufacturers for its advantages of environmental protection, high efficiency, stable film thickness and high film quality. However, compared to the overall coating of vacuum, the local coating of the atmosphere is more flexible.
For some parts that need to be coated separately, such as the buttons and earpieces of mobile phones, etcAtmospheric plasma nanocoatingLocal treatment can be realized, and there is no need to mask other parts when the coating is carried out, and it does not affect the subsequent assembly processes such as adhesive and lamination, so as to improve work efficiency and reduce production costs.
The image above shows the effect of the same PR4 plate after local plasma nanocoating, and the hydrophobic performance on the left is significantly higher than that on the right.
How plasma nano coatings work
Plasma nano coating refers to the evaporation of specific gas or liquid monomers into the plasma cavity, in the high-frequency electromagnetic field polymer monomer is ionized into plasma, the ionized polymer monomer ions polymerization reaction occurs between the polymer monomer ions to form polymer polymer, the production of polymer nanoparticles, polymer nanoparticles on the surface of the material or product to form nano films.
According to the needs of different application scenarios, atmospheric plasma nano coating can provide waterproof, oil-proof and corrosion-resistant protective film for the whole or part of electronic products, Bluetooth headset IPX7 waterproof, mobile phone button and earpiece waterproof, PCB board waterproof, medical needles and other protective film layers.
The picture above shows the network**, invaded and deleted.
Characteristics of plasma nano coating layer: Hydrophobic and oleophobic coating layer;Good temperature resistance;Nano-thick film, colorless and transparent;Partial coating is possibleThe coating stability is good.
Practical case of plasma nano coating - mobile phone button coating
As we all know, smartphones need to avoid water ingress or residual water stains as much as possible during use, so as to avoid water erosion of circuit boards and components, resulting in damaged circuits and impaired functions. But there are many holes or gaps in the phone, such as the earpiece, side buttons, speakers, charging holes, etc. Therefore, in order to avoid water or moisture in the mobile phone, a nano waterproof film can be coated on the gap between the side button and the earpiece to prevent the penetration of water or oily liquid and realize the waterproof function of electronic products.
