Ultrasonic Spray Coating Technology

Ultrasonic
Spray Coating System

Completely replaces traditional compressed air spraying methods that waste materials. Ultrasonic technology uses high-frequency vibrations to atomize liquids into ultra-fine, uniform mists.

Vietsonic pioneers the development of industrial-grade automated spray coating systems (system-level), meeting the strict standards of the electronics, medical, and advanced materials industries.

✦ Technological Breakthrough

The Revolution in Material Savings & Surface Optimization

Our system solves the toughest challenges in high-precision industrial surface coating.

01
 

Eliminate Overspray

Low-velocity mist particles adhere directly to the target instead of floating into the environment. Save up to 80% on expensive chemicals.

0%material savings
 
02
 

Uniform Coating Thickness

Precisely control coating thickness at the micrometer or nanometer level, leaving no streaks, drips, or air bubbles on the product surface.

✦ Multi-Industry Applications

Customized Applications for Diverse Industries

Designed with a flexible modular structure, Vietsonic systems are ready to meet all specialized factory requirements.

Electronics & Semiconductors

Requires extremely precise thin-film coating on components, circuit boards, and semiconductor wafers — where traditional methods completely fail to meet the required resolution.

  • Flux Spraying — Precise pattern coating on each SMT solder pad, strictly controlling flux volume.
  • PCB Conformal Coating — Protective coating against moisture, chemicals, and vibration for PCBs/PCBAs to IPC-A-610 standards.
  • Photoresist Spraying — Coating photo-resist, perovskite, and functional layers for photovoltaic cells.
PCB Conformal Coating
 

Medical Devices

Demands absolute precision and strict sterile conditions. Vietsonic systems meet Class 10000 cleanroom standards and are biocompatible.

  • Blood Collection Tubes (Vacutainer) — Uniformly and stably spray anticoagulants (EDTA, heparin) into the tubes at pL/sec flow rates.
  • Cardiovascular Stents — Ultra-thin, uniform drug-eluting coating on metal stent surfaces, controlling drug release rates.
  • Biomedical Dressings — Antibacterial, collagen, and stem cell material coating on medical scaffolds.

Energy & Advanced Materials

Advanced applications in R&D and manufacturing of next-generation renewable energy devices, requiring nano-level material structure control.

  • Fuel Cells — Spraying catalyst ink (Pt/C) onto proton exchange membranes (PEM/MEA) with optimal uniform catalyst density.
  • Anti-Reflective (AR) Coating — Coating SiO₂/TiO₂ nanoparticles onto displays, automotive glass, and industrial glass.
  • Perovskite Solar Cells — Coating active perovskite and HTL/ETL layers for next-generation photovoltaic modules.
