MEMS and sensor precision coating technology: empowering high-performance iteration of precision devices

In the current era of rapid iteration of intelligent sensing, precision manufacturing, and biological detection technology, the performance accuracy, service life, and operational stability of MEMS devices and various precision sensors directly determine the user experience and core quality of terminal devices, and precision coating technology is the key core process for optimizing device performance. In response to the precision and miniaturization characteristics of sensors and MEMS devices, specialized ultrasonic spraying technology can be customized to prepare various functional coatings and protective coatings, fully adapting to the diversified application needs of precision devices.

This process can achieve precise preparation of various functional coatings, covering mainstream application categories in the industry, including catalytic metal oxide films, conductive and dielectric functional layers, enzyme and biometric functional material coatings, as well as hydrophobic and silicone protective layers. Different coatings have their own functions. Metal oxide catalytic films can enhance the sensitivity of device sensing response, while conductive and dielectric layers ensure stable electrical transmission performance of the device. Biometric coatings are suitable for precision scenarios such as biosensing and medical detection. Hydrophobic and silicone protective layers can effectively isolate water vapor, dust, and corrosive media, building a reliable protective barrier for the device.

Compared to traditional spraying processes, ultrasonic low-speed atomization technology has extremely strong precision adaptability, perfectly adapting to the sensitive device characteristics of MEMS and sensors. The entire process involves low-pressure non-contact operation, which will not damage micro precision structures and fragile chip substrates. At the same time, it can achieve precise control of coating thickness and porosity, completely solving problems such as uneven coating thickness, material agglomeration, and coating defects in traditional processes, greatly improving coating uniformity and adhesion.

In addition, the coating process has strong adaptability to different scenarios and can achieve full process technology implementation. It can meet the needs of laboratory small-scale research and development, sample testing, as well as panel level batch processing and roll to roll continuous production mode, achieving seamless process migration from research and development to mass production. After coating optimization, MEMS and sensor devices have significantly improved coating adhesion, making them less prone to detachment and peeling, effectively extending device lifespan. At the same time, stable optimization of electrical performance, sensing accuracy, and environmental tolerance helps precision sensor devices achieve high-performance and large-scale applications in consumer electronics, industrial testing, biomedicine, smart wearables, and other fields.
