Polyimide Material Spray Coating Ultrasonic spraying is an efficient process for preparing polyimide films. The core is to use ultrasonic vibration to atomize the polyimide precursor solution into micrometer sized droplets, which are then uniformly deposited on the substrate surface and subjected to high-temperature imidization to form a thin film. This process is particularly suitable for fields such as flexible electronics and semiconductors that require strict performance of [...]

Flux Spraying Production Line System Flux Spraying Production Line System - Ultrasonic Spray Fluxing - Cheersonic In modern electronic manufacturing, the reliability and quality of printed circuit boards (PCBs) directly determine the performance and lifespan of the final electronic products. As a key link in the PCB production process, flux coating technology has a decisive impact on the subsequent soldering quality, including solder joint integrity, conductivity stability, and [...]

Photoresist Coverage In semiconductor manufacturing and precision photolithography, uniform photoresist coverage directly determines chip performance and production yield. Traditional coating technologies face challenges such as insufficient precision and material waste. Ultrasonic adhesive dispensers, with their cutting-edge technology, have become a revolutionary option for photoresist coating. Ultrasonic adhesive dispensers use high-frequency ultrasonic vibrations to instantly break diluted photoresist into countless small, mist-like droplets. These droplets, precisely sized according to [...]

How is PI Coated onto a Glass Substrate? How is PI coated onto a glass substrate? How is PI liquid converted into PI film? The following is a breakdown of the specific process: 1. Glass substrate cleaning: Generally, EUV cleaning is performed first, followed by brush cleaning, high-pressure water vapor spray cleaning, and finally A/K drying. EUV cleaning: By irradiating the surface of a glass substrate with 172nm [...]
