When it comes to how to deburr a PCB circuit board, many people immediately think of washing and grinding. Washing and grinding is the most commonly used deburring method at present. It is a way to remove burrs by using the friction between the grinding stone and the workpiece. Compared with many deburring methods, low initial investment cost and simple operation are its advantages. However, with the continuous improvement of industrial requirements, the situation of dominating the world begins to break down, and more and more new methods are applied to the field of deburring , There are more electrochemical methods, electrothermal methods, sandblasting, ultrasonic and so on.
The process is a soaking process, and CULLYGRAT is a solution. This circuit board product utilizes the difference in substrate structure and burrs, and through the principle of vertical reaction, selectively achieves the effect of removing PCB circuit board burrs. Compared with the traditional chemical deburring, the circuit board process has made great progress in all aspects. Especially in terms of reliability, repeatability, stability and environmental protection, it is far superior to the traditional process. The following is the process The performance is briefly introduced as follows.
1. Improve the surface finish of circuit board productsUsing this process to deal with burrs can also improve the surface finish of the circuit board of the workpiece, so as to achieve the polishing effect. When the workpiece is processed by various methods, its plane has a roughness in different degrees. When it is processed by this process, this index can be well reduced, because this process can selectively react vertically to the product. Let the uneven plane gradually approach the plane.
2. Efficient and time-saving
Compared with the traditional process, the process has been greatly improved in processing time. Deburring by this process generally only takes a few minutes, and the shortest product only takes tens of seconds. The specific situation depends on the material of the product, the size of the burr and the processing requirements of the customer. Another manifestation of high efficiency and time saving is that the process can be widely used in mass production. Due to the high reproducibility and reliability of this product, the processed products have high consistency in terms of precision and color size, especially in terms of size control, and its precision can even reach micron requirements. . All of these provide guarantees for its wide range of industrial applications.
3. It can enhance the anti-corrosion and anti-corrosion ability of the product
Using this process can better combine the anti-rust layer and the product to better protect the workpiece. For this process, some customers have done salt spray test, and found that there are products treated by this process, which can greatly extend the salt spray test time.
4. Safe and reliable, environmentally friendly and economical, easy to operate
Using this process for deburring treatment has the characteristics of safety, reliability and environmental protection. The main surface of safety is in two aspects. The first is product safety, which mainly means that the processed products have high quality assurance, and the mechanical properties and physical and chemical properties of the products will not be changed due to the process. In addition, it also includes the safety performance of the product itself, which has MSDS safety certification. Second. Operation and personnel safety. The process does not require specialized technicians to operate. Operators only need to go through simple training to work, and when operating, they only need to pay attention to the safety of general chemical reagents and agents. When it comes to environmental protection, this product complies with ROHS certification, which is also an important guarantee for its long-term application in Bosch, Germany.
5. Wide range of applications
Whether a product can adopt this process mainly depends on the material and processing requirements of the PCB circuit board product. It is not affected by its processing method and geometric shape. The PCB materials it targets are mainly iron copper, aluminum and its alloy materials. So far, it has successfully applied more than 200 kinds of circuit board materials. The application field is more extensive, especially in various machining and mechanical and electronic manufacturing fields. Even more special.
6. It can improve the electroplating effect and phosphating amount of the product, and prevent hydrogen embrittlement
Since this product can generally improve the surface finish of the product, it is beneficial to improve the electroplating adhesion of the product, thereby improving the electroplating effect. In addition, the use of this process can prevent hydrogen embrittlement, because the use of this process will not form a closed space, which is beneficial to prevent the acidic substances during electroplating from staying inside the workpiece, thereby preventing hydrogen from entering the internal material of the workpiece and causing to helium crisp
