PCB cleaning machine processing is an efficient and environmentally friendly surface treatment technology. Plasma cleaning machines can clean, activate, and modify the surface of PCBs, thereby improving the quality and performance of PCBs.


Today, please follow the editor to learn more about the advantages of plasma cleaning technology widely used in the PCB manufacturing process, as follows:


Firstly, vacuum plasma cleaning can remove organic pollutants such as tiny oxides and particles from the surface of PCBs, achieving high cleanliness and meeting subsequent process requirements. Plasma cleaning technology can introduce active groups, such as hydroxyl groups (- OH) and carboxyl groups (- COOH), to improve surface activity, enhance adhesion between solder pads and solder, coatings and substrates, and improve welding and coating quality.


Secondly, vacuum plasma processing machines generally use gases such as oxygen and argon as cleaning media, avoiding the use of chemical solvents and reducing environmental pollution. The plasma can evenly cover the surface of the PCB, ensuring that every part can be effectively treated. Vacuum plasma cleaning is a non-contact processing method that will not cause mechanical damage to the PCB surface.


In general, virtual soldering and false soldering often occur during the PCB welding process. Using a plasma cleaning machine to clean and activate the solder pads can significantly improve the welding quality, reducing virtual soldering and false soldering by 90%. The adhesion of the PCB surface coating is insufficient, resulting in coating detachment. Using a plasma processing machine to coat the PCB surface can further improve the adhesion of the coating after treatment.

Finally, plasma cleaning equipment has great potential in the field of circuit boards due to its cleaning, activation, modification, and environmental protection characteristics. PCB plasma cleaning machines can effectively clean the surface, improve surface energy, enhance adhesion, improve welding quality, and significantly improve the performance and reliability of PCBs.

Next, the operational process and advantages of the vacuum plasma cleaning machine in the field of circuit boards will be subdivided:


1. The plasma cleaning machine uses active particles in the plasma to undergo chemical reactions with organic matter, decomposing it into volatile substances such as carbon dioxide and water, thereby thoroughly removing organic matter and providing a clean surface for subsequent processes. With the physical bombardment and gas flow effects of plasma cleaning, the cleanliness of the PCB surface is ensured.


The interaction between plasma and PCB surface introduces polar groups such as hydroxyl and carboxyl groups, which can significantly improve the surface. A high surface area is beneficial for subsequent processes such as welding and bonding, which can enhance the wettability between the solder and the PCB surface, allowing the solder to spread better and improving the welding quality.


2. Plasma cleaning is a dry cleaning process that dries the surface of the cleaned PCB and allows it to proceed directly to the next process, such as component mounting and solder resist coating, without the need for additional drying treatment. It can be well connected to various PCB manufacturing processes, improving production efficiency and product quality


3. Plasma cleaning can change the roughness of the PCB surface. Increasing the roughness appropriately can increase the contact area of the surface, enhance adhesion, and facilitate the bonding of materials such as solder resist and character ink with the PCB surface, preventing detachment and other issues.


4. During the welding process, a good intermetallic compound is formed to reduce welding defects such as virtual soldering and false soldering, improve the mechanical strength and electrical performance of the welding points, and thus enhance the reliability of the entire PCB assembly.


5. If there are pollutants on the surface of the PCB, it may cause insulation performance degradation, short circuits, and other problems. Plasma cleaning equipment can remove these impurities, help maintain good insulation performance, and ensure the stable operation of the PCB in the electrical system.


In summary, plasma surface equipment manufacturers can help achieve effective cleaning and activation treatment based on the characteristics of customer materials by adjusting process parameters, which has strong processability.
