Automatic Single Track PCB Cleaning Machine for SMT Line

The HDY-390clean PCB Cleaning Machine is a high-performance, single-track automated cleaning system engineered for modern SMT production lines. Designed to remove dust, flux residue, and particulates from PCB surfaces before assembly or testing, it integrates electrostatic discharge (ESD) protection, spiral anti-static brushes, and a quiet high-pressure vacuum system for optimal cleaning results. With a working range of 50*50mm to 500*390mm, it supports flexible production needs. When cleaning is not required, it can function as a standard conveyor, maximizing equipment utilization. Controlled by a Yuhang PLC and Weinview touch screen, it also supports automatic step motor width adjustment and MES system connectivity for smart factory integration.

Compared to conventional PCB cleaners, the HDY-390clean offers:

Ideal for:

• Pre-reflow oven cleaning – Remove flux residue before reflow soldering.

• Post-AOI/SPI inspection – Clean PCBs after optical inspection to prevent false calls.

• Before conformal coating or potting – Ensure surface cleanliness for coating adhesion.

• High-reliability electronics – Medical, automotive, aerospace, and industrial PCBs requiring ESD-safe handling.

• Smart Factory / Industry 4.0 – Compatible with MES for traceability and OEE tracking.

Q1: Can this machine work as a normal conveyor when cleaning is not needed?

✅ Yes. The HDY-390clean features a bypass/conveyor mode – simply disable the cleaning function, and it operates as a standard left-to-right conveyor.

Q2: What is the maximum PCB size it can handle?

✅ Supports PCBs from 50*50mm up to 500*390mm – ideal for most consumer, industrial, and automotive boards.

Q3: How does the ESD protection work?

✅ It uses an automatic ion bar that detects and releases positive & negative ions to neutralize static charges on the PCB surface, ensuring product safety.

Q4: Is the cleaning speed adjustable?

✅ Yes. The stepper motor transmission speed is fully adjustable from 0 to 17.5 meters per minute, allowing customization per board type and dirt level.

Q5: Can it connect to our MES system?

✅ Absolutely. The machine supports MES integration via PLC communication protocols (RS485/Modbus TCP), enabling real-time production data upload.

Q6: What kind of brush is used? Is it safe for sensitive components?

✅ It uses spiral anti-static brushes made of conductive fiber – gentle on gold fingers, ICs, and fine-pitch components. No scratching or damage.

Q7: How loud is the vacuum fan?

✅ Engineered with quiet high-pressure technology – noise level is below 65dB, suitable for cleanrooms and operator-friendly environments.

Q8: What power supply and control components are used?

✅ Powered by Mingwei power supply, controlled by Yuhang PLC, with Weinview touch screen and Omron relays – all industrial-grade for reliability.
