Multi-layer circuit boards are actually made by laminating and bonding several etched single or double-sided boards. So, what are the advantages of multilayer circuit boards compared with single and double-sided circuit boards?

1. Multilayer circuit boards have high assembly density and small size; as the volume of electronic products becomes smaller and smaller, the demand for multilayer circuit boards is also increasing.

2. The multi-layer circuit board is convenient for wiring, the wiring length is greatly shortened, and the connection between components is shortened, thereby increasing the speed of signal transmission.

3. For high-frequency circuits PCB, after adding the ground layer, the signal line will form a constant low impedance to the ground layer, the circuit impedance is greatly reduced, and the shielding effect is better.

4.For electronic products with high heat dissipation requirements, multilayer circuit boards can be equipped with a metal core heat dissipation layer, which is convenient to meet the needs of special functions such as shielding and heat dissipation.

In terms of performance, multi-layer circuit boards are better than single and double panels, but the higher the number of layers are, the greater the production cost will be, the processing time will be long relatively, and the quality inspection will be more complicated .

Generally, multi-layer circuit boards have been widely used in the manufacture of electronic products due to their design flexibility, economic superiority, stable electrical performance and reliability. At present, Honlynn Circuits can produce 1-40 layers of circuit boards, and has the ability to quickly serve the entire industry chain from design to delivery.
