What is inside of PCBs? Smartphones have dozens of components, and they are all connected thru a vast labyrinth of wires inside the PCB! So how exactly do PCBs work?

PCBs may be incredibly complex, however, they are rather easy to design and order. For a quick turnaround and inexpensive option for buying any variety of PCB, consider PCBWay: https://www.pcbway.com/
