PCBs (Printed Circuit Boards) come in rigid, flexible, and rigid-flex types, with variations in thickness, materials, and layers (single-sided, double-sided, or multilayer), offering advantages like high density, reliability, design flexibility, and manufacturability for use in complex electronic systems.
The “layers” in PCB design refer to the actual physical copper layers of a circuit board, with modern designs often including multiple layers for routing and power distribution, while concepts like vias, silk screen, SMD components, and fill areas must be carefully managed to ensure a functional and manufacturable design.

To determine the number of layers in a PCB, observe the via holes and light transmission: if vias are visible on both sides, it’s likely a 4-layer board; if vias are visible only on one side or light passes through them, it could be a 6/8-layer board; multilayer boards with opaque inner cores may have many more layers.
