What are the advantages of the application of multilayer PCB circuit boards

Multilayer boards are the most widely used type of board in daily life. So what are the application advantages of multi-layer PCB circuit boards:

1. High assembly density, small size and light weight, meeting the needs of light and small electronic equipment;

2. Due to the high assembly density, the connection between components (including components) is reduced, the installation is simple, and the reliability is high;

3. Due to the repeatability and consistency of the graphics, reducing wiring and assembly errors, saving equipment maintenance, debugging and inspection time;

4. Can increase the number of wiring layers, thereby increasing design flexibility;

5.Can form a circuit with a certain impedance, can form a high-speed transmission circuit;

6.Can set the circuit, magnetic circuit shielding layer, can also set the metal core heat dissipation layer to meet the special functions of shielding, heat dissipation.

With the continuous development of electronic technology and the continuous improvement of electronic equipment requirements in the computer, medical, aviation and other industries, the circuit board is shrinking in size, quality is reduced, and density is increasing. Due to the limited space available, single-sided and double-sided printed boards have made it impossible to further increase the assembly density. Therefore, it is necessary to consider the use of a multilayer circuit board having a higher number of layers and a higher assembly density. Multi-layer circuit boards have been widely used in the manufacture of electronic products due to their flexible design, stable and reliable electrical performance and superior economic performance.
