Advantages of multilayer circuit boards
circuit board determines the process difficulty and processing price according to the number of wiring surfaces. ordinary circuit boards are divided into single-panel and double-panel. However, high-end electronic products are limited by product space design factors. In addition to surface wiring, multi-layer wiring can also be superimposed inside. In the production process, after a layer of circuit is completed, it is positioned and pressed by optical equipment so that the multilayer circuit is superimposed on a circuit board, commonly known as multilayer circuit board .
Multi-layer circuit board is currently the most widely used circuit board type in daily life. has the following advantages:
1. High assembly density, small size and light weight;
2. Due to the high assembly density, the wiring between components is reduced, the installation is simple, and the reliability is high;
3. Due to the repeatability and consistency of the graphics, wiring and assembly errors are reduced, and equipment maintenance, debugging and inspection time are saved;
4. The number of wiring layers can be increased, thereby increasing design flexibility;
5. A circuit with a certain impedance can be formed, and a high-speed transmission circuit can be formed;
6. A circuit and a magnetic circuit shielding layer can be set, You can also set a metal core heat dissipation layer to meet the needs of special functions such as shielding and heat dissipation.
With the continuous development of electronic technology, computer, medical, aviation and other industries are constantly improving the requirements for electronic equipment, circuit boards are developing in the direction of reducing volume, reducing quality and increasing density. Due to the limitation of available space, single-sided and double-sided boards cannot further increase the assembly density, so it is necessary to consider using multilayer circuit board with more layers and higher assembly density. Multilayer circuit board has been widely used in the manufacture of electronic products because of its flexible design, stable and reliable electrical performance, and superior economic performance.

In the graphic electroplating process method of multi-layer circuit board factory, because the circuit pattern is easy to produce side etching in the etching process, the tin-lead alloy plating part is in the air and produces a suspension layer, which is easy to fall off, resulting in a short circuit caused by bridging between wires. Multilayer circuit board factory uses infrared hot melt process method, can make the exposed copper surface get very good protection. However, when it is used for infrared thermal melting of multi-layer circuit boards, the phenomenon of delamination and foaming between layers of multi-layer circuit boards is very serious due to high temperature, resulting in a very low yield of multi-layer circuit boards. _Blind buried hole circuit board_multilayer circuit board

Before designing multilayer circuit boards, the multilayer circuit board structure must be determined according to the circuit scale, circuit board size and electromagnetic compatibility (EMC) requirements. That is to decide whether to use a 4-layer, 6-layer or higher multilayer circuit board. Once the number of layers is determined, the multilayer circuit board factory has decided to determine the placement of the electrical layers in the multilayer circuit board and how to distribute different signals on these layers. This is the choice of multilayer circuit board factory laminated structure.
