PCB cleaning machines with surface dust and electrostatic discharge (ESD) removal systems have become increasingly popular. Many newcomers may wonder, “Isn’t a PCB board ready for use straight away?” However, during various stages such as handling, barcoding, and placement of PCBs, dust and stains may accumulate on the surface layer, and static electricity on the PCB surface may attract dust particles. With the advancement of technology and the continuous miniaturization of components, even minor stains can directly affect soldering results, while larger stains may cause short circuits or potential defects in solder joints. Additionally, Electrostatic Discharge (ESD) and Electrostatic Overstress (EOS) phenomena have become new challenges for component manufacturers.
Fully automatic PCB surface cleaning machines are suitable for online cleaning of small debris, dust, fibers, hair, skin flakes, metal particles, and other contaminants on PCB solder pad surfaces before solder paste printing or adhesive coating. The role of fully automatic PCB surface cleaning machines is to ensure that the PCB surface layer is clean, thereby eliminating defects such as virtual soldering, voids, warping, and misalignment in advance, reducing risks, and improving product quality. These machines are specially designed equipment developed to meet the PCB cleaning needs of SMT production lines. They come standard with antistatic functionality to completely eliminate static interference. Using a contact cleaning method, these machines achieve a cleaning rate of over 99%, ensuring efficient, stable, and long-lasting cleaning results.
Advantages of PCB Cleaning Machines:
- Touchscreen control interface for easy operation.
- Feeding direction of the track can be switched freely, from left to right or right to left.
- Front-end equipped with a brush function for stronger debris and hair removal capabilities.
- Antistatic devices are installed at the entrance and exit of the PCB board to reduce patching defects and electrostatic damage caused during the patching process.
- Features counting and CNC speed display functions.
- Reminder function for replacing sticky dust roll paper.
- Antistatic cleaning brushes and vacuum dust removal devices designed and developed according to the high cleaning requirements of PCB boards ensure efficient, stable cleaning results.
In summary, PCB surface cleaning improves SMT yield. Here, the “surface layer” refers to the nodes on the PCB that provide electrical connections between electronic components or other systems to the PCB circuit, such as solder pads or contact connections. Although bare copper has good solderability, it is highly susceptible to oxidation when exposed to air and easily contaminated. Hence, surface cleaning of PCBs is essential. This concludes the content of PCB cleaning machines with surface dust and electrostatic discharge removal systems, and I hope it helps you.
