Before designing a printed circuit board, you need to decide whether
you'll use a single-layer or multi-layer PCB. Usually the complex
devices typically use multi-layer boards, while simpler ones can benefit
from single-layer. This blog is going to explain the advantages and
disadvantages of the multilayer boards.

As we all know, Multi-layer PCBs are made of three or more double-sided
boards stacked on top of each other. Theoretically, they can contain as
many boards as you can need, but this should be on the base of the
capability of a factory. For Fast Turn PCB, we can make up to 36 layers
for the rigid pcb prototype.
With the following advantages, multi-layer pcb stands ahead in the pcb industry:
1.Applied in more advanced devices
For the projects involves more circuits and components, multi-layer
board ensures there is ample room for connections, making it ideal for
more advanced devices with many different uses and advanced
capabilities.
2.Increased Durability
The multi-layer boards can withstand in harsher conditions and often last longer than the single-sided boards do.
3.High Quality
When designing the multi-layer boards, it requires more special skills
and advanced tool for it to meet its use in the advanced devices. Most
of them will contain the impedance control and special techniques like
backdrilling, laser drilling and so on for the fabrication. Thus, it
also requires the higher standard for the monitoring equipment to ensure
its quality.
4.Smaller and lighter weight
Multi-layer circuits adopted the high-tech to stack layers on top of
each other to integrate the high layer and multi-functions into a
tighter space. And this makes the circuits smaller and lighter. And
nowadays, the IC technology is becoming more and more popular for the
smaller and lighter board while containing more functions.
