In daily life, the multi-layer PCB circuit board is currently the most widely used circuit board type. With such an important proportion, it must benefit from the many advantages of the multi-layer PCB circuit board. Let’s take a look at the advantages.
5. It can form a circuit with a certain impedance, which 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 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 multilayer 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 due to their flexible design, stable and reliable electrical performance and superior economic performance.
