Ultrasonic Spray Flux Equipment for PCB Manufacturing

Cheersonic produced ultrasonic spray flux equipment for PCB manufacturing. The spray flux system can reduce the consumption of flux by up to 80%, so it quickly won praise and recognition in the industry. Over the years, Cheersonic’s ultrasonic flux system has won a reputation for performance, reliability and strong support worldwide, and has consolidated the company’s position in the ultrasonic spray flux industry.

Cheersonic continues to innovate and adds unique and innovative features of the UEC2100 series. The latest is the air-entrained molding system, which further improves the performance of spray molding. Compared with other sprayed fluxes, UEC2100 can greatly reduce flux consumption, and has better through-hole penetration and top filling. In order to solve the challenges faced by PCB manufacturers today, Cheersonic ultrasonic spray flux is not only designed for no-clean fluxes, but also for corrosive water-soluble fluxes and high-solid rosin fluxes.

Ultrasonic spray flux equipment is a high-precision industrial device specially designed for flux coating procedures in PCB manufacturing, serving as a core auxiliary unit for wave soldering and selective soldering processes. Different from traditional pressure spray and foam fluxing devices, it adopts advanced ultrasonic atomization technology to achieve efficient and uniform flux application for various circuit boards.

The equipment’s core working principle relies on piezoelectric transducers, which convert high-frequency electrical signals into 20kHz to 120kHz mechanical vibrations. These high-frequency vibrations break the liquid flux into uniform micron-sized droplets ranging from 5μm to 50μm. With the guidance of directional low-speed airflow, the tiny droplets are evenly and softly deposited on PCB pad surfaces and welding areas without damaging delicate circuit structures and micro-components.

This equipment boasts prominent industrial advantages. It features ultra-uniform coating with controllable thickness, effectively eliminating missing coating, excessive flux accumulation and dead zones common in traditional processes. The non-clogging nozzle design greatly reduces maintenance frequency, cutting daily operation costs. Meanwhile, it minimizes flux waste by precisely controlling spray volume, lowering material consumption and waste liquid discharge.

Compatible with water-based, alcohol-based and no-clean fluxes, it adapts to high-precision PCB production needs including fine-pitch boards and flip chips. It effectively avoids die float and poor soldering, stabilizes welding quality, improves production yield, and is widely integrated into automated PCB production lines for high-efficiency, eco-friendly and high-precision manufacturing.
