Development trend of PCB industry

The technological development of PCB industry is closely related to the demand of downstream electronic terminal products. With the rapid development of electronic information technology and the acceleration of the upgrading of electronic products, the new generation of electronic products are developing in the direction of miniaturization, portability and multi-function, promoting the development of PCB products in the direction of high-density, high-performance and environment-friendly.

1. High-density

High-density puts forward higher requirements for the aperture size, wiring width, and number of layers of the circuit board. HDI is the embodiment of advanced PCB technology. Compared with ordinary multilayer boards, HDI accurately sets blind holes and buried holes to reduce the number of through-holes, save PCB wiring area, and significantly improve the density of components.

2. High performance

High-performance mainly refers to improving the performance of PCB in impedance and heat dissipation, so as to enhance the reliability of products. Modern electronic products require fast information transmission rate and large amount of information transmission, which promotes the development of digital signal technology towards high frequency. Only a PCB with good impedance can ensure the effective transmission of information, ensure the stability of the final product performance, and realize complex functions. Due to the large amount of heat generated by high-performance products, PCBs with good heat dissipation performance are required to reduce the temperature of products. In this trend, PCBs with good heat dissipation performance such as metal substrates and thick copper plates are widely used, and PCB products are characterized by high-performance development.

3. Environmental protection development

The production process of PCB industry is complex, some of which will pollute the environment, and the pollutant treatment process is relatively complex. With the improvement of environmental protection requirements of various countries, the PCB industry has formulated a series of environmental protection specifications. In consideration of the need for sustainable development, the use of new environmental protection materials and the improvement of process technology to produce energy-saving and environment-friendly new products will also become the development direction of the PCB industry.
