Printed circuit boards (PCBs) are widely used in various electronic products, with their core function being to connect electronic components and achieve smooth transmission of electrical and signal signals.

From an application perspective, communication network infrastructure is one of the most important application areas for PCBs.

PCB products are mainly divided based on the number of circuit layers, product structure, and product usage. It can be divided into various types such as single/double-sided board, multi-layer board, HDI, packaging substrate, and flexible board.

Among them, multi-layer boards account for 38% of the PCB market. According to Prismark data, the market size of multi-layer boards reached 26.5 billion US dollars in 2023,

Multilayer boards can be further divided into midsole boards and high-rise boards, among which high-rise boards play a key role in communication equipment, high-end servers, military and other fields.

Single panel is the most basic type of PCB, mainly used in basic electronic products such as ordinary household appliances and electronic remote controllers.

Double sided panels are more suitable for complex circuits such as consumer electronics, computers, and automotive electronics due to their double-sided wiring.

In addition, the demand for products such as high multilayer boards, advanced HDI boards, and packaging substrates continues to grow.

The introduction of HDI technology further reduces the PCB wiring space and component spacing, greatly improving the integration and performance of servers.
