There are a total of 8 processes in PCB making: inner layer, pressing, drilling, electroplating, outer layer, solder mask, processing, and testing.
In the traditional sense, the process of making PCB boards adopts the method of chemical corrosion, which is only suitable for mass production, and has long production cycle, high cost, and great damage to the environment. However, in real work, a large part of PCB boards do not need mass production, and are often produced in small batches or even very small batches. In a specific environment, such as a school, students and teachers need extremely small batch production when doing design, competition, scientific research and other projects. So, the PCB CNC machine with high efficiency and low cost has good practical significance.
