PCB manufacturers talk about the application advantages of multi-layer PCB circuit boards
Application advantages of multi-layer PCB circuit boards:
1. High assembly density, small size and light weight, meeting the needs of light and miniaturization of electronic equipment;
2, due to the high assembly density, the wiring between the components (including components) is reduced, the installation is simple, and the reliability is high;
3. Due to the repeatability and consistency of the graphics, the wiring and assembly errors are reduced, and the maintenance, debugging and inspection time of the equipment is saved;
4. The number of wiring layers can be increased, thereby increasing design flexibility;
5, can form a circuit with some impedance, can form a high-speed transmission circuit;
6. Circuit, magnetic circuit shielding layer can be set, and metal core heat dissipation layer can also be set 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 electronic equipment requirements in the computer, medical, aviation and other industries, circuit boards are 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 have been impossible to achieve a further increase in assembly density. Therefore, it is necessary to consider the use of multi-layer circuit boards with a higher number of layers and 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.
