The plate technology has made great progress in all aspects, especially in terms of reliability, repeatability, stability, environmental protection and so on, which is far superior to the traditional process. The process performance is briefly introduced below.
1. Improve the surface finish of PCB products
Using this process to treat burrs can also improve the surface smoothness of the workpiece board to achieve a polishing effect. When the workpiece is processed in various ways, the surface of the workpiece has varying degrees of roughness. When the workpiece is processed by this process, the index can be lowered very well. This is because the process can be selectively perpendicular to the product reaction such that the uneven surface gradually becomes planar.
2. Efficient time saving
Compared with the traditional process, the processing time of the process has been greatly improved. This process usually takes only a few minutes to deburr. The shortest product takes only a few tens of seconds. More specifically, it 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 method can be widely used for mass production. Due to its high repeatability and reliability, processed products are highly consistent in terms of accuracy and color size, especially in terms of dimensional control, which meets micron requirements. All of this guarantees its wide application in the industry.
3. Enhance the corrosion resistance and corrosion resistance of the product
This process can better combine the anti-rust layer with the product to better protect the workpiece. For this process, some customers have conducted salt spray tests. The results show that the product treated by this process can greatly extend the salt spray test time.
4. Safe and reliable, environmentally friendly and economical, easy to operate
This process is safe, reliable and environmentally friendly for deburring. The main surface of safety has two aspects. First, product safety, mainly refers to the high quality assurance of processed products, and will not change the mechanical properties and physical and chemical properties of the products due to the process. In addition, it also includes the security features of the product itself, with MSDS security certification. Second, operation and personnel safety. The process does not require professional technicians to operate, the operator only needs simple training, and in operation, only pay attention to the general chemical test, and the agent operation is safe. In terms of environmental protection, this product is ROHS certified, which is also an important guarantee for its long-term application in Bosch, Germany.
When removing the deburring of the PCB board, many people immediately think of washing and grinding. Washing is one of the most common deburring methods at present. This is a method of deburring by using friction between the grindstone and the workpiece. Compared with many deburring methods, the initial investment cost is low and the operation is simple, which is one of its advantages. However, as the industrial requirements continue to increase, the unification situation begins to decompose. More and more new methods are being applied in the deburring field. More and more electrochemical methods, electrothermal method, sand blasting method, ultrasonic method and so on. The following PCB factory introduced a new deburring method: the chemical deburring method.
This process is a soaking process and CULLYGRAT is a solution. PCB products can selectively remove PCB board burrs by utilizing differences in substrate structure and burrs as well as vertical reaction principles. Compared to traditional chemical deburring, circuits
5. Wide range of applications
Whether the product can be used in this process depends mainly on the material and processing requirements of the PCB board product and is not affected by its processing mode and geometry. Its PCB material is mainly iron, copper, aluminum and its alloys. So far, PCB materials have been successfully applied to more than 200 kinds of PCB materials, and their application range is wider, especially in various fields of machining, machinery and electronics manufacturing.
6, can improve the plating effect and phosphating amount of the product to prevent hydrogen embrittlement.
Since the product generally improves the surface finish of the product, it is advantageous for improving the plating adhesion of the product, thereby improving the plating effect. Further, hydrogen embrittlement can be prevented by using the process because the process does not form a closed space, which is advantageous in preventing the acidic substance from remaining inside the workpiece during the plating process, thereby preventing hydrogen element from entering the internal material of the workpiece and causing hydrogen embrittlement.
