Printing Circuit Board ("PCB") is a bridge that carries electronic components and connects the circuit. Function is to make various electronic components form a connection of predetermined circuits to play a transmission effect. As a key component of electronic products, PCB is applied to almost all electronic products. It is an indispensable electronic component in modern electronic information products and is known as the "mother of electronic products". The manufacturing quality of PCB does not directly affect the reliability of electronic products, and affects the integrity of signal transmission between chips and chips. Essence

The global PCB market presents the attribute of "cycle+growth", and the electronic trend of downstream terminals has promoted the long -term space of PCB. On the one hand, PCB, as a basic electronic component, continues to increase with the trend of downstream terminal electronicization. On the other hand, PCB is influenced by the macroeconomic demand for electronic products. With the transfer of the PCB industry, the market size of PCB is also expanding. According to PRISMARK statistics, the global PCB industry market space is US $ 61.34 billion, and the compound growth rate of industry compounds in 2019-2024 is 4.3%.

The important substrate of PCB is the copper covering plate. From a cost perspective, the copper-covering plate of important substrates accounts for about 30%-40%of the entire PCB manufacturing.

The main raw materials of the copper -covered plate are glass fiber cloth, wood pulp paper, copper foil, epoxy resin and other materials. Among them, copper foil is the main raw material for making copper -covering plates, accounting for 80%of the proportion of materials. The copper -covering industry is an industry with a large demand for funds and a relatively high concentration.

According to PRISMARK's survey data, the global copper -covered board industry CR10 reaches 75%and CR5 is 52%, which has a high concentration. Among them, the market share of Shengyi Technology is 12%. The CR10 of the PCB industry on the downstream of the copper plate is 26%, which is a complete competitive industry. In recent years, the PCB industry has developed rapidly. Whether it is the number and scale of upstream service companies, the timely delivery, or other supporting services, it can meet the needs of the industry. The upstream has formed a relatively concentrated and stable supply pattern.

The downstream application field of PCB has been wide. In recent years, industry has become more diversified. Product applications have covered communication electronics, consumer electronics, computers, automotive electronics, industrial control, medical equipment, national defense and aerospace and other fields. Among them, the three major areas of communication, automotive electronics and consumer electronics account for 60%. The acceleration of the construction of 5G base stations will drive the rapid development of the PCB industry chain. The corporate revenue of the PCB industry is mainly determined by downstream demand. For PCB manufacturers, its profit margin is closely related to its own product structure, production scale, yield and production line automation level in addition to the downstream demand and upstream supply. High -level PCB products such as HDI and flexible circuit boards are usually higher than traditional PCB products; large -scale production is conducive to PCB manufacturers to dilute fixed costs to increase profit margins.
