The high degree of customization is the most important characteristic of PCBs. There are significant differences in the usage scenarios, products, performance, materials, areas, and other aspects of PCBs, resulting in significant changes in the types of components used, the thickness of connecting wires, and the density of wiring. This requires PCB companies to have strong customized production capabilities.

　　Although the PCB industry has some common basic processes, the most important thing is to determine different production processes and equipment based on the accuracy requirements of substrate thickness and material, line width and distance, design structure and production scale, as well as other specific requirements specified by customers, resulting in significant differences in production prices. So, do you know what the cost components of PCB circuit boards are?

　　The production process of PCB is relatively complicated, usually involving more than 40 processes such as inner layer production, blackening, pressing, drilling, electroplating, etc. For example, rigid circuit boards typically include processes such as exposure, development, etching, copper plating, and film removal. Although PCBs have strong customization characteristics, these most basic processes are necessary, but there may be differences in specific parameters.

　　Although the process is cumbersome, in fact, each process of PCB is already a relatively mature process, so the technological differences between PCB companies are not significant, and it is difficult to achieve high profits through technological differences. Due to the small differences in technology, cost control ability has become the most critical factor in the profitability of PCB enterprises. Cost control is reflected in all aspects of a company's operations, which directly depends on the company's management level and needs to start from details.
