40 kHz OEM ultrasonic wave‑soldering flux coating is a process employing ultrasonic vibration to atomize and apply liquid flux onto target surfaces. Within the flux‑coating unit, liquid flux is fed to the nozzle. An ultrasonic transducer generates high‑frequency vibration, which atomizes the flux and distributes it evenly across welding zones. Driven by ultrasonic high‑frequency oscillation, the atomized droplets feature fine, consistent particle sizes. Droplets travel at relatively high velocity during spraying, enabling thorough coverage over target work surfaces.

It is necessary to elaborate on soldering flux itself, a critical material for electronic assembly, generally formulated from rosin blended with other chemical components. Its core purpose is to support reliable, consistent welding operations. During soldering, flux removes oxides present on solder and base‑material surfaces, keeps metal substrates clean, inhibits in‑process oxidation, lowers solder surface tension, and optimizes overall soldering quality.

Flux is available in solid, liquid and gaseous forms. Its key functions cover: facilitating heat transfer, oxide removal, reducing surface tension of workpieces, eliminating surface contaminants to expand effective bonding areas, and preventing re‑oxidation. Ultrasonic spraying systems are seeing growing adoption across the flux‑application sector.

1. Electronic Component Coating In modern digital manufacturing workflows, ultrasonic spraying technology enables precise flux deposition on circuit boards and electronic component surfaces, delivering consistent and reliable soldering quality.

2. Solder Joint Protection Flux applied via ultrasonic spraying forms a protective layer over solder joints. It effectively resists surface oxidation and external contamination throughout and after the soldering process, greatly enhancing long-term welding stability and product reliability.

3. High-precision Uniform Coating Ultrasonic spraying is ideal for scenarios requiring ultra-fine and uniform flux coverage. It produces finely atomized flux droplets with even distribution, ensuring full, consistent protection for every individual solder joint without excess or missing coating.
