Detailed explanation on how PCB manufacturers deburr PCB

PCB manufacturers, PCB designers and PCBA manufacturers explain how PCB manufacturers deburr PCB in detail

When it comes to deburring PCB, many people immediately think of washing and grinding. Washing and grinding is the most commonly used deburring method, which is a way of deburring by friction between grinding stone and workpiece. Compared with many deburring methods, the low initial investment cost and simple operation are its advantages. However, with the continuous improvement of industrial requirements, the situation of its dominance begins to decompose, and more and more new methods are applied to the deburring field, such as electrochemical methods, electrothermal methods, sandblasting, ultrasonic, etc.

This process is a soaking process, and CULLYGRAT is a solution. This PCB product uses the difference between the base material structure and the burr, through the principle of vertical reaction, to selectively remove the burr of PCB. Compared with traditional chemical deburring, this PCB process has made great progress in all aspects, especially in reliability, repeatability, stability, environmental protection, etc. It is far superior to the traditional process. The following is a brief introduction to the process performance.

1. Improve the surface finish of circuit board products

The process 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 in various ways, its plane has a roughness in varying degrees. When it is processed by this process, this index can be well reduced. This is because this process can selectively vertically react to the product, so that the concave convex non plane gradually approaches the flat surface.

2. Efficient and time-saving

Compared with the traditional process, the treatment time of this process has been greatly improved. It usually takes only a few minutes to deburr with this process, and only tens of seconds for the shortest product. More specifically, it depends on the material of the product, the size of the burr and the customer's processing requirements. Another performance of high efficiency and time saving is that the process can be widely used in batch production. Due to the high reproducibility and reliability of the product, the processed product has high consistency in terms of precision and color size, especially in terms of size control, its precision can meet the requirements of micrometers. All these provide guarantee for its wide range of industrial applications.

3. It can enhance the corrosion resistance of products

The use of this process can better combine the antirust layer with the product, so as to better protect the workpiece. For this process, some customers have done salt spray test, and it is found that the products treated by this process can greatly extend the salt spray test time.

4. Safe and reliable, environment-friendly and economical, simple operation

The deburring process is safe, reliable and environmentally friendly. Safety mainly covers two aspects. First, product safety mainly refers to that the processed products have high quality assurance and will not change the mechanical properties and physical and chemical properties of products due to the process. In addition, it also includes the security performance of the product itself, which has MSDS security certification. Second, operation and personnel safety. This process does not require special technicians to operate, and operators can take up their posts only after simple training, and only need to pay attention to the safety of general chemical test and agent operation during operation. 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.

5. Wide application range

Whether a product can adopt this process mainly depends on the material and processing requirements of the PCB product, and is not affected by its processing method, geometric shape, etc. Its PCB materials are mainly iron, copper, aluminum and their alloy materials. Up to now, its successful application of PCB materials has reached more than 200, with more extensive application fields, especially in various machining and mechanical, electronic manufacturing fields.

6. It can improve the electroplating effect and phosphating amount of products and prevent hydrogen embrittlement

Because the product can generally improve the surface finish of the product, which is conducive to improving the electroplating adhesion of the product, thereby improving the electroplating effect. In addition, this process can prevent hydrogen embrittlement, because it will not form a confined space, which is conducive to preventing acid substances from staying inside the workpiece during electroplating, thus preventing hydrogen from entering the internal material of the workpiece and causing hydrogen embrittlement.
