PCB (Printed Circuit Board) and Integrated Circuit (IC) are two core components in electronic products. There are the following differences between them:
Different working principles
A PCB board is a plate-shaped substrate used to connect different electronic components, including wires, resistors, capacitors, and other components, for building circuits. Integrated circuits integrate multiple components from a semiconductor chip onto a single chip. It integrates many different circuit components onto a small chip through microfabrication technology, forming a complex circuit system. This integration method can significantly reduce circuit size and improve circuit reliability and efficiency.

Different structures
A PCB board is a circuit board consisting of one or more layers of printed circuits, typically containing copper foil, sterilizing agents, ink, etc. Integrated circuits, on the other hand, are chips made of semiconductor materials. Generally, circuit circuits are carved onto a very thin silicon wafer and then the entire chip is packaged.

Different application scope
PCB boards are widely used in circuit board assembly and electronic devices, commonly found in electronic products such as televisions, mobile phones, and computers. Integrated circuits are the core components applied in digital electronic products, such as computers, mobile phones, washing machines, air conditioners, automobiles, medical equipment, and so on.
The above are the main differences between PCB boards and integrated circuits, which have different application scenarios and roles in the field of electronic engineering.
