(Summary description)Application of plasma surface treatment equipment in camera modules such as infrared cut-off filters: In the past decade or so, the surface treatment technology of plasma surface treatment equipment has been widely used in the camera module industry. The camera module products involved in vacuum plasma surface treatment equipment cleaning include many products, such as infrared cut-off filters, Mobile phone cameras, car cameras, and vacuum plasma surface treatment equipment are how to clean these products to prepare for the next process. Plasma treatment of infrared cut filter: The infrared cross-section filter makes full use of the precision optical coating technology. The optical substrate is alternately coated with high and low refractive index optical films, which can achieve high light transmission and near-infrared cross-section filters in the visible light region. By adding in the imaging system The infrared cross-section filter can block some of the infrared rays that will affect the imaging quality, thereby improving the imaging quality and obtaining a better visual presentation. Why does this kind of optical filter adopt plasma surface treatment process? In order to remove impurities and residues on the surface of the infrared cut-off filter, ultrasonic cleaning and centrifugal water washing are usually used, but this method alone cannot form an ultra-clean substrate surface. At this time, it is necessary to introduce vacuum plasma surface treatment equipment. Cleaning treatment, vacuum plasma surface treatment equipment can achieve surface cleaning, surface activation, surface etching, surface coating, so that it can not only remove some organic residues on the infrared cut filter that are difficult to see with the naked eye, but also achieve Surface activation and etching functions to improve the quality and yield of the coating. Application of plasma treatment process for mobile phone camera module: The mobile phone camera module was also mentioned in the previous introduction, which is actually the camera and camera module built into the mobile phone. Its composition is more sophisticated and complex, mainly including the lens, imaging chip, PCB and FPC circuit board, as well as several parts of the camera module of the mobile phone, that is, the connector that connects to the motherboard of the mobile phone. With the development of smart phone multi-camera technology, mobile phone camera modules are developing rapidly in a positive direction. Process application of plasma processing technology in mobile phone camera modules: In fact, plasma processing technology is widely used in mobile phone camera modules. There are many products that can be processed, such as filters, brackets, circuit board pads, etc., and infrared rays. The cut-off filter has the same treatment effect. The plasma surface treatment process can remove organic contaminants on the surface of the above-mentioned material, and can also activate and roughen the surface of the material, which can improve the bonding performance between the bracket and the filter, and improve Reliability of wire bonding, and product yield, etc. Application of plasma technology for on-board camera module: The application of plasma surface treatment machine equipment in vehicle camera module, compared with the application of mobile phone camera module, the main processing products are vehicle lens, vehicle camera module bracket, etc., which can improve the reliability of the product, enhance the bonding ability, and improve the product Yield rate, reducing production costs.
