Analysis of Ultrasonic Spraying Flux Technology: Efficient and Accurate Electronic Manufacturing Solutions

In the field of electronic manufacturing, uniform coating of flux directly affects welding quality and product reliability. Traditional spraying methods are prone to spattering, waste and uneven coverage, while ultrasonic spraying flux technology is becoming a new trend in the industry with its high precision, low loss and environmental protection characteristics. This article will explore its working principle, core advantages and typical applications in depth to help you optimize your production process.

Principle of Ultrasonic Spraying Flux Technology

Ultrasonic spraying technology uses high-frequency vibration (such as 50kHz ultrasonic system) to atomize liquid flux into micron-sized droplets (10~50μm) and achieve uniform deposition through precise control. Its core components include:

1. Ultrasonic generator: generates high-frequency electrical signals to drive the transducer to vibrate.
2. Atomizing nozzle: nozzle-free design to avoid clogging, suitable for high solid content flux.
3. Liquid supply system: Dual pump liquid supply technology is used to ensure stable flow and prevent interruption or overspraying.

Compared with traditional air pressure spraying, ultrasonic spraying does not require compressed air, reduces droplet scattering, and increases material utilization to more than 90%.

Five core advantages of ultrasonic spray flux

1. Ultra-high precision, suitable for fine pads
– It can spray extremely thin coatings (as low as 1μm), suitable for high-density PCB, BGA, QFN and other precision components, avoiding bridging or cold soldering.

2. Uniform coverage, improve welding yield
– The droplets are evenly distributed, without “orange peel effect”, ensuring the consistency of solder joints and reducing rework costs.

3. High efficiency and energy saving, reducing production costs
– Material waste is reduced by more than 50%, and long-term use can significantly reduce the purchase cost of flux.

4. Environmental protection and safety
– Reduce VOC emissions, cleaner working environment, and meet green manufacturing requirements.

5. Intelligent control, adapt to automated production lines
– Support PLC or industrial computer programming to achieve selective spraying and adapt to different pad layouts.

Typical application scenarios

1. PCB wave soldering/reflow soldering pre-treatment
– Evenly spray flux before soldering to enhance wettability and improve solder joint reliability.

2. Semiconductor packaging
– Suitable for Flip Chip and wafer-level packaging, accurately control the amount of flux to avoid contamination of non-welding areas.

3. Precision electronic component welding
– Such as 5G communication modules, automotive electronics, etc., to ensure high-quality coating of tiny pads.
