With the continuous upgrading of precision standards in the optoelectronic, semiconductor and precision machinery industries, the requirements for surface protection, optical performance, insulation and wear resistance of components have been constantly improved. Traditional processes such as spraying and dip coating rely on physical adhesion for forming, resulting in loose and uneven coatings with weak adhesion, which are prone to peeling, color difference, pinholes and other defects. Meanwhile, they may damage the reference precision of precision workpieces and fail to meet the thin film preparation standards for high-end components. With the vacuum precision deposition process, the
Wafer Coatering Machine has become the core processing equipment for surface modification of precision parts.
Adopting a sealed vacuum coating operation mode, the equipment isolates the interference of external impurities such as dust, moisture and oxygen, providing a highly clean and stable process environment for thin film deposition. Different from traditional surface treatment methods, the machine forms nano-to-micron functional thin films layer by layer on the surface of workpieces based on physical or chemical deposition principles. It can prepare various functional coatings including anti-reflection films, protective films, insulating films and hard wear-resistant films according to processing needs, suitable for various workpieces such as semiconductor wafers and ceramic components.
Equipped with an intelligent full-automatic control system, the whole machine can accurately control core parameters such as vacuum degree, deposition rate, process temperature and coating time. The whole process can be stored and reproduced, effectively solving the problems of uneven film thickness and large performance differences in batch processing. The coating process involves no strong contact or cutting damage, which can completely retain the original flatness precision and surface texture of workpieces. The formed film is dense and uniform with high bonding strength and excellent stability.
Components processed by the equipment have comprehensive improvements in wear resistance, oxidation resistance, corrosion resistance and optical performance, effectively extending the service life of products and reducing later operation and maintenance losses. Capable of both sample proofing and large-scale mass production, the equipment features high automation and stable yield, adapting to the standardized coating production of precision workpieces in multiple industries.
Relying on the core process advantages of high cleanliness, high precision and stable film layers, the Wafer Coatering Machine effectively breaks through the technical bottlenecks of traditional coating processing and has become an indispensable core process equipment in optoelectronic manufacturing, semiconductor packaging and the production of new energy precision parts.
