What are the Advantages of Using Multilayer PCB?

Nowadays, PCBs are very diversified in the electronics industry. Although the structural design and technology manufacturing requirements of general multilayer PCBs are relatively high, and the higher the number of layers, the greater the difficulty of manufacturing. But the multilayer PCB is particularly popular, because many complex electronic devices need to use it to realize their functions. Do you know the advantages of using multilayer PCB?

 

 

 

1. Smaller size

Because electronic products are developing towards the trend of small and precision, the size of PCB is getting smaller and smaller. One of the most prominent and acclaimed benefits of using multilayer printed circuit boards is their size. Due to the layered design of the multilayer PCB, the size of the multilayer PCB is reduced by increasing the number of layers, so it is smaller than other PCBs with similar functions. This has brought huge benefits to modern electronic products such as smartphones, laptops, tablets and wearable devices.

 

 

2. Lighter weight

As the PCB size is getting smaller and smaller, the size of the components is getting smaller and smaller. In the multi-layer PCB design, multiple connectors required for the interconnection of single-layer and double-layer PCBs are eliminated, thereby reducing weight. So it is a good choice for small electronic devices whose weight need to be considered.

 

 

3. More durable

The multi-layer PCB can not only bear its own weight, but also can be designed with a metal core heat dissipation layer, which is convenient to meet the functional requirements such as shielding and heat dissipation. Multi-layer PCBs can also use multiple insulating layers between circuit layers, combining them with prepreg adhesives and protective materials.

 

 

4. More convenient routing

The use of multi-layer PCB not only facilitates routing, but also shortens the routing length and the wiring between electronic components, and improves the speed of signal transmission.

 

 

5. Better shielding effect

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