Ultrasonic Coating of Precursor Solutions
Ultrasonic Coating of Precursor Solutions Process Principle Ultrasonic coating utilizes high-frequency ultrasonic vibrations (typically 20–120 kHz) to atomize a precursor solution into micron-sized droplets (typically in the 1–50 μm range). These droplets are then directed onto the substrate surface using a carrier gas (e.g., nitrogen, argon, or other inert gases), ultimately depositing them into a uniform thin film. Its core advantages include: – High-precision uniformity: Narrow droplet size distribution enables [...]
