1.0  Advantages of multilayer PCB

1.1 Smaller size

How amazing that the biggest advantage of multilayer PCB is the smaller size. What is to deserve to be mentioned, multilayer PCBs can reduce the size while retaining full functions, which makes them often used in powerful, small and convenient electronic devices (for example: Smart phones, Smart wearable devices, Laptops and so on).

1.2 Lighter weight

As the removal of multiple connectors that exist between single-layer board and double-layer PCBs in the interconnection and the adoption of multilayer design patterns. This greatly reduces the weight of the multilayer PCB. This advantage greatly improves the mobility, portability, and comfort of a wide variety of portable devices.

1.3 Higher quality

When starting to create a multilayer PCB, more complex processes and designs are required. This also makes the structure of multilayer PCBs more complex than that of single-layer and double-layer PCBs, resulting in better quality.

1.4 Longer durability

As for withstand greater heat and pressure, multilayer PCBs are made of better materials than other PCBs. In addition, the multilayer PCB also has multilayer insulation between each circuit layer. It makes the heat resistance, compression resistance and stability of multilayer PCB higher than that of single-layer and double-layer PCBs.

1.5 Stronger performance

Multilayer PCB is a circuit board with extremely high density. Not only does this allow for more layers to fit into a single PCB, but it also allows for tighter connections between layers. In this way, although there is a smaller size, it can have a faster response time and a larger capacity.

1.6 Single Connection Point

Because a multilayer PCB does not concatenate multiple PCB components, it simply designs a single unit. It appears to reduce the number of connection points, but it is beneficial for multilayer PCBs. There is only one connection point, but this optimizes the size and weight of the PCBs yet. This optimization is perfect for smaller electronic devices.

2.0 Conclusion

These advantages make multilayer PCBs extremely useful in a variety of devices, especially in mobile devices and Multi-functional electronics. Conversely, as many industries move to mobile solutions, multilayer PCBs are finding their place in a growing number of portable devices.

3.0 Suggestion

These advantages of multilayer PCBs make designers more willing to use them in more portable devices. However, multilayer PCBs are much more expensive to produce than single-layer and double-layer PCBs, and they also take more time to produce. Therefore, designers should analyze their own target product before using a multilayer PCB. The designer's target product meets the requirements before deciding whether to use a multilayer PCB，which is a suitable way to avoid unnecessary expenses.
