Product Detail:

Generally speaking, multi-layer PCBs are used for more complex devices, but 1 or 2 layer PCBs are used for simple devices. Undoubtedly, electronic engineers prefer to choose a multilayer PCB because it can provide high signal strength. A 2-layer PCB is the most common of all PCB types because it can accommodate interconnections on both sides. Therefore, we will explain the difference between a 2-layer PCB and a 4-layer PCB, and how to choose the right type for your project.
