Simply put, PCB routing is the process of using a PCB cutting machine to create a predetermined pattern or trace on a circuit board using a pre programmed milling cutter. This process is similar to carving patterns on wooden boards with woodworking tools, except that the tools are replaced with high-precision milling cutters and the materials are replaced with circuit boards.
Specifically, the routing machine can accurately process various shapes and sizes of holes, grooves, and other structures on the circuit board. These structures may be used for installing components, connecting circuits, or to meet specific design requirements. Compared with V-CUT (cutting V-shaped straight shallow grooves on both sides of the circuit board), the routing has better accuracy and flexibility. Although V-CUT is easy to operate, its accuracy is relatively low, and the connection interface after board separation may be rough; The routing can create various complex puzzle shapes on the board according to the program, with high dimensional accuracy and smooth interface.
According to its working principle and degree of automation, the routing machine can be divided into two types: manual type and mechanical type.
Manual routing, as the name suggests, is a tool that relies on workers manually adjusting the position of holes and using a drill bit to drill holes. Although this method is flexible, its efficiency is low and accuracy is limited by the level of operation of workers.
The mechanical routing is a device that uses mechanical principles to automatically complete the drilling process. It controls the motion trajectory of the milling cutter through a preset program, quickly and accurately completing machining tasks such as drilling and groove making.
The working process of a mechanical routing is roughly as follows: first, place the PCB board to be processed on the workbench of the gong board machine and fix it in place; Then, input the designed processing program into the control system of the gong board machine; Next, start the machine and the milling cutter will process on the circuit board according to the programmed path; Finally, after processing, remove the circuit board for further processing. The entire process is highly automated, greatly improving production efficiency and processing accuracy.
In the production process of PCB boards, the routing is an indispensable link. It is widely used in the processing of various circuit boards, whether it is single panel, double-sided board or multi-layer board, specific processing tasks need to be completed through a PCB. For example, in the PCB board of communication equipment, in order to install various chips, resistors, capacitors and other components, corresponding holes and grooves need to be machined on the circuit board; In computer motherboards, in order to connect core components such as CPUs, memory, and graphics cards, high-precision slots and interfaces also need to be machined through PCB.
In addition, the routing is also commonly used in the process of dividing circuit boards. In the production of PCB boards, in order to save materials and improve production efficiency, multiple circuit boards are usually spliced together for processing. After processing, they need to be separated by a routing machine. This process not only requires high precision, but also ensures that the edges of the segmented circuit board are smooth and free of burrs, so as not to affect subsequent installation and use. With the continuous development of electronic technology, the functionality and complexity of PCB boards are also constantly increasing. This poses higher requirements for routing technology. In order to meet market demand, routing machines are constantly developing towards high precision, high efficiency, and automation. For example, modern routing machines have been able to achieve multi axis linkage processing, which can produce more complex panel patterns in one go; Meanwhile, by introducing advanced control systems and sensor technology, the machining accuracy and stability of the gong board machine have also been significantly improved. In the future, with the rise of intelligent manufacturing and industrial Internet, routing technology will pay more attention to the integration with digitalization, networking and intelligence.
By building intelligent factories and digital production lines, comprehensive monitoring and optimization of the routing processing process can be achieved; By introducing big data and artificial intelligence technologies, deep mining and analysis of processing data can be conducted to provide strong support for production decision-making. All of these will drive the development of gong board technology to a higher level, providing more reliable, efficient, and flexible solutions for the manufacturing of electronic devices.
