♦ What's 4 Layer PCB?
A 4-layer PCB is a type of multilayer printed circuit board that consists of four conductive copper layers laminated together with insulating material (typically FR-4). These layers are interconnected through vias (plated holes) to form a complete circuit.
♦ Structure of a 4-Layer PCB:
A standard 4-layer PCB stack-up usually includes:
