What are the application advantages of multi-layer PCB boards?
In daily life, multi-layer PCB circuit boards are currently the most widely used type of circuit boards. Such an important proportion must benefit from the many advantages of multi-layer PCB circuit boards. Let's take a look at the advantages.
Application advantages of multi-layer PCB circuit boards:
1. Mixed Assembly has high density, small size and light weight, meeting the needs of light and miniaturization of electronic equipment;
2. Due to the high density of the Mixed Assembly, the wiring between the components (including components) is reduced, the installation is simple, and the reliability is high;
3. Because the graphics are repeatable and consistent, errors in wiring and assembly 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. Characteristic impedance PCB can form a circuit with a certain impedance, which can form a high-speed transmission circuit;
6, ceramics base copper-clad laminates and metal base printed board can be equipped with circuit, magnetic circuit shielding layer, and metal core heat dissipation layer can be provided to meet the needs of special functions such as shielding and heat dissipation.
With the continuous development of electronic technology and the continuous improvement of the requirements for electronic equipment in the computer, medical, aviation and other industries, the circuit board is developing in the direction of shrinking volume, reducing quality and increasing density. Due to the limitation of available space, single and double-sided printed boards cannot achieve further increase in assembly density. Therefore, it is necessary to consider the use of HDI PCBs with more layers and multi-layer circuit boards with higher assembly density. Multilayer circuit boards have been widely used in the manufacture of electronic products with their flexible design, stable and reliable electrical performance and superior economic performance.
