Multi -layer PCB generally refers to a circuit board above 3 слои. It has a multi -layer conductive material and insulating layer sandwiched together to form a complex circuit design.
As the leading PCB manufacturer in China, LST Technology has rich experience and professional knowledge in multi -layer PCB manufacturing. We can make up to 48 -layer circuit boards, and we provide EMS solutions for different customers.

Advantages of multi-layer circuit boards

1. Increased signal transmission speed and data processing capability. Multilayer circuit boards can realize high-speed serial communication and high-frequency digital signal processing by increasing the number of line layers.

2. Improve the system’s anti-interference ability and power stability. Multilayer circuit boards can use more ground and power supply layers, but also by adding shielding layers to reduce electromagnetic interference.

3. High flexibility. Multi-layer circuit boards can be layered according to different functional requirements to achieve a high degree of modularity and reusability, which helps to reduce design costs and shorten the development cycle.

4. Reduced power consumption and improved thermal performance. Multi-layer circuit boards can reduce power consumption by optimizing signal paths and reducing unnecessary connections, while metal-core heat dissipation layers can also be set up on multi-layer circuit boards to meet the requirements of shielding, heat dissipation and other special functions.

5. High assembly density and high size requirements. As electronic products become smaller and smaller, the electrical performance of the PCB also puts forward higher requirements, the demand for multilayer circuit boards is also growing. В то же время, the choice of multi-layer PCB circuit board laying line convenient, laying line length greatly shortened, electronic components between each other to reduce the laying line, but also to enhance the rate of data signal transmission.

6. High-frequency circuit performance. For high-frequency circuits, into the grounding layer, the signal line to the ground to produce a stable low characteristic impedance, the power circuit characteristic impedance is greatly reduced, the interception effect is obvious.
