Ultrasonic Spray Coating for Electronic
Ultrasonic spraying technology has a wide range of applications in the electronics industry, mainly used for coating and protecting precision electronic components such as chips, circuit boards, and display screens.
In the electronics industry, this technology can accurately control the distribution of coatings, avoid performance problems caused by coatings that are too thick or too thin, reduce pollution, and improve product reliability and service life
Photoresist
Photoresist is a corrosion-resistant thin film material used in semiconductor manufacturing, optical device manufacturing, and optoelectronic fields. As a key material, photoresist coating quality directly affects the performance and reliability of the final product. Ultrasonic spraying technology has revolutionized the photoresist coating process.
Photoresist plays an important role as a corrosion-resistant coating material in photolithography processes. When semiconductor materials undergo surface treatment, the high uniformity of photoresist spraying enables precise images to appear on the material surface. Photoresist has been widely used in tasks that require extremely high precision graphic processing, such as display panels, integrated circuits, and semiconductor discrete devices.
Semiconductor
In the semiconductor manufacturing process, surface treatment directly affects the performance and reliability of the product.
Due to the precise and efficient spraying effect of ultrasonic spraying, it has been widely used in semiconductor processing
- Chip packaging: Through ultrasonic spraying technology, coatings with thermal conductivity, insulation, moisture resistance and other properties are evenly sprayed on the surface of the chip, effectively improving the reliability and service life of the chip.
- Chip processing: Cleaning and protective agents are sprayed onto the surface of the chip through ultrasonic spraying, effectively removing impurities and pollutants from the chip surface while providing protection against damage during processing
- Thin film preparation: The corresponding coating is sprayed onto the substrate through an ultrasonic spraying system, and then subjected to high temperature treatment to prepare uniform and dense functional thin films, which improve the performance of semiconductors such as metal thin films, insulating thin films, etc.
PCB Fluxing
PCB soldering flux is a chemical substance used in the soldering process, whose main function is to help solder better wet, spread, and adhere to metal surfaces, reduce soldering resistance, improve soldering quality, reduce soldering defects, and effectively prevent oxidation, protecting solder joints from environmental erosion.
Ultrasonic spraying process has become the standard process for PCB soldering flux and is replacing traditional air spray and foam spray processes to provide high-precision, high-uniformity, low-VOCs emission flux solutions.
Flip Chip Fluxing
In the flip chip packaging process, ultrasonic spraying technology is a high-precision and high-efficiency flux coating method, which is mainly used to form a uniform, ultra-thin flux layer between the chip bumps and the substrate pads to ensure welding quality and reliability.
