30kHz Low Power Custom Ultrasonic Atomizing Scattering Spray Nozzles These nozzles use low-pressure air/gas to produce uniform, wide spray patterns. The maximum spray width of each single nozzle reaches 9.8 inches (25 cm), depending on the distance to the substrate. Air flow velocity is adjustable to achieve low or high impact of atomized spray on parts or substrates. Multiple nozzles arranged in series can provide unlimited coating width. The scattering nozzle design delivers large spray coverage with high repeatability while keeping a compact nozzle profile.

 

Typical applications of the 30kHz low-power custom ultrasonic atomizing scattering nozzles include photoresist coating for semiconductor chips, where photoresist material is sprayed onto semiconductor wafers. Thanks to the rotational diffusion of mist generated by the scattering-type ultrasonic nozzle, uniform photoresist films can be formed not only on the wafer surface, but also on sidewalls and corners of wafer microstructures. Besides, scattering ultrasonic nozzles are also suitable for thin-film solar cell coatings, calcium titanate solar cell coatings, AR transmission & reflection coatings, insulating coatings, superhydrophobic coatings, PCB flux coating and other processes.

10. High-precision controllable spraying

 

 

 

1. Ultrasonic Frequency

Low-viscosity corrosion inhibitor:

Frequency setting:

Higher frequencies (e.g. 40 kHz or above) can be selected to achieve fine atomization.

High-viscosity corrosion inhibitor:

Frequency setting:

Lower frequencies (e.g. 30 kHz) are required to increase the liquid vibration amplitude and improve atomization performance.

 

2. Nozzle Air Pressure

Low-viscosity corrosion inhibitor:

Pressure setting:

The liquid atomizes easily, so low nozzle air pressure (0.1–0.3 MPa) is generally adopted.

High-viscosity corrosion inhibitor:

Pressure setting:

Higher nozzle air pressure (0.3–0.5 MPa) shall be applied to overcome high liquid viscosity and guarantee proper spraying results.

 

3. Spray Travel Speed

Low-viscosity corrosion inhibitor:

Speed setting:

The spray travel speed can be appropriately increased to avoid over-coating and dripping.

High-viscosity corrosion inhibitor:

Speed setting:

The spray travel speed shall be reduced to ensure uniform coating and prevent dripping or sagging.

 

4. Coating Thickness

Low-viscosity corrosion inhibitor:

Thickness setting: Relatively thin coatings can be applied, normally at the level of several micrometers.

High-viscosity corrosion inhibitor:

Thickness setting:

Slightly thicker coatings can be configured, typically ranging from several micrometers to more than ten micrometers.

 

5. Ambient Temperature & Humidity

Temperature:

Higher temperature generally reduces the viscosity of the inhibitor and benefits spraying. However, the temperature must not exceed the heat resistance limit of the corrosion inhibitor.

Humidity:

Humidity should be kept within a suitable range. Excessive humidity may impair the curing performance of the corrosion inhibitor.

 

6. Coating Duration

Low-viscosity corrosion inhibitor:

Good fluidity allows shorter coating duration.

High-viscosity corrosion inhibitor:

Longer coating duration is required to achieve uniform coating.
